Understanding Binding in TR-31 Protocols
The payments industry is undergoing a critical transition. Financial institutions are moving away from outdated key management methods and adopting TR–31–compliant protocols to meet PCI PIN requirements and strengthen cryptographic security. While much of the conversation around TR-31 focuses on compliance deadlines and migration strategies, one critical concept often flies under the radar: binding.
At Trusted Security Solutions, we’ve seen firsthand how a lack of understanding about binding can slow projects, create security gaps and put compliance at risk. So, let’s break it down.
What Is Binding?
In simple terms, binding is the process of securely linking two components in your ATM environment—most often the Encrypting PIN Pad (EPP) and your key management system (such as the TSS A98).
When binding is performed correctly, it ensures that cryptographic keys exchanged between these systems are unique to that pairing and cannot be intercepted or reused elsewhere. Without binding, attackers could potentially manipulate or substitute devices, undermining the integrity of your entire ATM network.
Why Binding Matters in TR-31 Migrations
We’ve noticed a recurring trend: many institutions don’t realize they need to account for binding until they’re already mid-project. By then, delays and complications often arise. As institutions migrate to TR-31 protocols, binding becomes a foundational step in securing the key exchange process, and unfortunately, it’s also one of the most misunderstood.
Here’s why binding is essential:
- It prevents security gaps. Binding ensures that the EPP and the A98 are cryptographically linked, protecting against unauthorized key injection or substitution
- It reduces migration risk. Skipping or mishandling binding can derail your transition to TR-31 compliance
- It’s a compliance requirement. Regulators expect institutions to properly bind devices and document the process
Common Challenges With Binding
Institutions that overlook binding often encounter:
- Unexpected downtime. Maintenance becomes complicated if devices aren’t properly unbound before servicing
- Data mismatches. Binding data must match between the EPP and the A98—if it doesn’t, operations grind to a halt
- Vendor confusion. Different ATM manufacturers handle binding differently, making interoperability a challenge without expert guidance
How TSS Helps Simplify Binding
Binding doesn’t have to be a barrier. At TSS, our team of experts works with all major ATM manufacturers to ensure the A98 remains interoperable and ahead of evolving standards. We guide institutions through the binding process step by step—ensuring it’s done correctly the first time and minimizing disruption to operations.

What the 2025 ATM Security Trends Report Reveals About the Future of Key Management
The ATM ecosystem is experiencing one of its most significant shifts in decades. Between regulatory deadlines, new encryption standards and the rise of more sophisticated cyberattacks, financial institutions face a complex security environment that demands both awareness and action.
To help industry leaders prepare, we’ve released the 2025 ATM Security Trends Report—a comprehensive look at what’s happening now, what’s on the horizon and how banks, credit unions and processors can take proactive steps to secure their ATM networks.
The Current Landscape: Why ATM Security Is at a Crossroads
For years, the ATM industry has relied on traditional cryptographic methods and manual processes to manage keys. While these systems have been foundational, they’re increasingly vulnerable to evolving attack vectors and out of step with modern compliance mandates.
Here’s what’s changing:
- Regulatory bodies are enforcing change. PCI PIN mandates require migration to TR-31 and TR-34 standards, which modernize how institutions exchange and protect cryptographic keys
- Threat actors are growing more sophisticated. Logical attacks and PQC (post-quantum cryptography) risks expose weak points in legacy systems
- Institutions need operational efficiency. Manual key loading is no longer scalable, and inefficiencies add unnecessary risk and cost
The 2025 report highlights how these trends converge, creating risk and opportunity for organizations willing to act now.
Key Insights From the 2025 Report
While the full report goes deep into security protocols and technology shifts, here are a few critical themes worth noting:
- TR-31 and TR-34 compliance will shape the next decade. These standards move the industry away from insecure, manual processes and toward automated, asymmetric key exchanges. Early adopters will avoid the last-minute scramble that has plagued previous compliance transitions.
- Post-quantum cryptography can’t be ignored. Quantum computing is no longer theoretical—it’s advancing rapidly. Institutions must begin exploring PQC strategies now, or risk finding themselves unprepared for a cryptographic landscape that could shift overnight.
- Remote Key Loading (RKL) is no longer optional. RKL solutions enable institutions to securely and efficiently load keys across large ATM fleets without manual intervention. The efficiency gains alone are substantial, but the security and compliance benefits make it essential.
- Vendor partnerships are critical. The ecosystem is complex. Banks and credit unions must ensure their solutions are interoperable across different ATM manufacturers, processors and vendors. Trusted partners can help avoid costly missteps.
Why Institutions Should Act Now
ATM security is not a “wait until next year” challenge. Delaying migration or ignoring looming threats can lead to rushed projects, budget overruns and compliance violations. Proactive institutions are already investing in scalable key management strategies, assessing their networks for vulnerabilities and creating roadmaps for TR-31, TR-34 and PQC readiness.
The 2025 ATM Security Trends Report offers a roadmap for navigating this complexity. It doesn’t just highlight risks, it provides practical steps for institutions to strengthen their security posture while optimizing operational efficiency.

From MKL to RKL: When and Why to Make the Switch in ATM Security
The way you manage cryptographic keys is no longer just an IT detail—it’s a core business decision. ATM fleets, processors and financial institutions are under pressure to deliver secure, seamless customer experiences while protecting against increasingly sophisticated threats. In this environment, your approach to key management can make the difference between resilience and risk.
For decades, Manual Key Loading (MKL) has been the default. Teams meet at ATMs in pairs, enter keys manually and follow cumbersome procedures to remain compliant. But as technology evolves and threats multiply, relying solely on MKL is like running your business on dial-up in a fiber-optic world.
That’s why institutions are asking: When should I upgrade from MKL to RKL? The answer is simple: now.
The Security Imperative
MKL exposes institutions to one unavoidable truth: every manual touchpoint increases risk. Each key ceremony involves people, paper and physical presence—all of which are vulnerable to human error.
By contrast, Remote Key Loading (RKL) automates the process. Keys are securely transmitted and injected using asymmetric cryptography, drastically reducing exposure to clear-text keys or mishandling.
For CISOs, compliance officers and security leaders, the benefits are clear:
- Stronger protection against fraud and insider risk
- Built-in compliance with PCI PIN standards such as TR-31 and TR-34
- Future-proofing as regulators push toward eliminating outdated methods
When auditors arrive, RKL speaks for itself: a hardened, automated process that leaves less room for error and more confidence in your compliance posture.
The Operational Advantage
Ask any COO or operations leader about MKL and you’ll hear the same pain points: scheduling two-person teams, driving to locations and taking ATMs offline for key ceremonies. Each visit costs time, labor and—most critically—downtime for your customers.
RKL changes the equation. With keys delivered electronically, institutions can:
- Reduce truck rolls and in-person key ceremonies
- Minimize ATM downtime and disruption for cardholders
- Free up staff to focus on higher-value work instead of routine key management
For operations leaders, this isn’t just an upgrade in security. It’s an upgrade in efficiency.
The Business Case for Leadership
From the CEO’s perspective, every technology decision is based on ROI, reputation and resilience. RKL delivers on all three.
- Cost Savings: Less downtime and fewer truck rolls mean lower operating costs over time
- Customer Trust: A single compromise can tarnish your institution’s reputation. RKL shows proactive investment in security
- Scalability: As your ATM fleet grows or consolidates, RKL ensures your cryptographic infrastructure can keep pace
In short, RKL is a strategic investment in protecting your business and brand.
Why the Time Is Now
Every day that passes with MKL as your standard is another day of unnecessary risk, inefficiency and added cost. The move to RKL is no longer a matter of if—it’s a matter of when.
For financial institutions, processors and OEMs, the smartest move is to transition before regulatory mandates or security incidents force your hand. Early adopters aren’t just compliant—they’re confident, efficient and better prepared for the future.
Ready to Upgrade?
At Trusted Security Solutions, we’ve helped institutions of every size move seamlessly from MKL to RKL. Our A98 ATM Key Management System is designed to meet you where you are today and scale with you tomorrow.

TR-31 vs. TR-34: What’s the Difference?
In the world of ATM security and key management, compliance with industry standards is essential to ensure secure operations and maintain customer trust. Two commonly discussed standards are TR-31 and TR-34, each addressing distinct aspects of encryption key management and distribution. While both are vital to financial institutions, understanding their differences can help you determine how they apply to your operations.
This article provides an overview of TR-31 and TR-34, their primary functions, differences and how they benefit financial institutions in enhancing encryption key management and compliance.
What Is TR-31?
TR-31, short for Technical Report 31, governs the secure storage and transmission of symmetric cryptographic keys during their operational life cycle. It provides a framework for managing symmetric cryptographic keys in a standardized format, focusing on:
1. Key Block Format:
TR-31 defines how encryption keys are arranged within a key block to ensure secure storage and transfer. These key blocks contain metadata that specifies how the key is intended to be used, aiding in clear identification and management of each key.
Common metadata includes:
- Algorithm information
- Usage information
- Distribution information
2. Operational Key Management:
It ensures the secure handling of cryptographic keys as they perform functions like encrypting PINs or facilitating secure communications. Learn more about TR-31 and how the TSS A98 Key Management System simplifies ATM key management.
3. Compliance with Standards:
TR-31 enhances institutions ability to comply with regulatory requirements by protecting keys during their entire lifecycle, from generation to eventual retirement.
What Is TR-34?
TR-34, or Technical Report 34, focuses on the initial distribution and injection of asymmetric crytographic keys into secure devices like ATMs and payment terminals. This standard facilitates:
1. Remote Key Distribution:
TR-34 supports the secure generation and delivery of keys from a central key management system to an endpoint, such as an ATM’s secure cryptographic module.
2. Public Key Infrastructure (PKI):
Unlike TR-31, TR-34 utilizes PKI for key delivery, utilizing certificates to ensure that both the sender (key management system) and receiver (ATM) are authenticated and trusted.
3. Key Initialization:
TR-34 is specifically designed for key injection, ensuring that secure devices begin their operations with the necessary encryption keys already in place.
Key Differences Between TR-31 and TR-34
| Characteristic | TR-31 | TR-34 |
|---|---|---|
| Primary Focus | Secure management of operational encryption keys | Initial distribution and injection of keys |
| Technology Used | Private Shared Symmetric Key | Public Key Infrastructure (PKI) |
| Purpose | Securely stores and transmits data | Establishes secure initial key relationships |
| Encryption | Symmetric encryption | Asymmetric encryption |
How They Work Together
TR-31 and TR-34 are not competing standards but complementary ones. While TR-34 ensures that cryptographic keys are securely distributed to devices, TR-31 takes over once those keys are in use, ensuring their secure handling throughout their lifecycle. Together, they form a robust framework for end-to-end encryption key management.
Why Understanding These Standards Matters
For financial institutions and ATM management companies, compliance with TR-31 and TR-34 is more than a regulatory requirement—it’s a critical step in protecting sensitive customer data and maintaining trust. Adopting solutions that support both standards ensures that your organization is prepared for the evolving landscape of digital security.

How ATM Key Management Systems, Like the A98, Help Reduce Fraud and Enhance Security
In today’s financial landscape, where cyber threats are evolving rapidly, securing ATM networks is more critical than ever. Financial institutions, from large banks to credit unions, must protect their ATMs from fraud while meeting stringent compliance requirements. One of the most effective tools for achieving this is a robust ATM Key Management System like the A98 from Trusted Security Solutions (TSS).
ATM key management is the cornerstone of secure ATM operations, ensuring that sensitive data remains encrypted and protected from malicious actors. In this blog, we’ll explore how the A98 Key Management System helps reduce fraud, enhance security and streamline operations. We’ll also highlight the benefits of Remote Key Loading (RKL) and the Comvelope System, for ATMs that don’t support RKL, showing why the A98 is the gold standard in ATM security.
Why ATM Key Management is Essential
ATM key management refers to the process of securely generating, distributing and installing encryption keys that protect communications between ATMs and a financial institution’s host network. Without proper key management, ATMs are vulnerable to:
- Fraudulent Attacks: Unauthorized access can lead to stolen funds or compromised customer data.
- Cyber Threats: Outdated or poorly managed keys create security gaps that hackers can exploit.
- Compliance Violations: Failing to meet security standards (such as TR-31) can result in penalties and reputational damage.
Robust key management ensures that encryption keys are securely handled and updated, maintaining the integrity of ATM networks and protecting against fraud.
The Challenges of Traditional Manual Key Loading (MKL)
Manual Key Loading (MKL) has long been the standard for ATM key management. In an MKL process, encryption keys are split into multiple components and entered manually by two or more authorized technicians. While this method is the minimum requirement for ATM compliance, it comes with significant complexities and challenges:
- Human Error: A single mistake during key entry can invalidate the key, causing downtime and security vulnerabilities.
- Logistical Complexity: MKL requires the presence of multiple technicians on-site, which increases labor expenses and adds logistical challenges due to the need for secure coordination, storage and management of key components for ATM repairs or updates.
- Scalability Issues: Managing keys for a large ATM fleet is time-consuming and inefficient.
While secure, MKL is resource-intensive and prone to errors, making it less suitable for modern, large-scale ATM operations.
