sectors. Cryptography's ubiquitous presence makes it difficult to track assets that organizations may not even be aware of. Although not subject to the May deadline, Enterprises must also identify and proactively manage their cryptographic assets. It is crucial for all organizations to follow a structured approach for transitioning to a post-quantum world. Consider the following steps: Step 1: Inventory The first step is to inventory all cryptographic systems, including certificates and algorithms, and prioritize them based on their level of criticality. This process entails understanding the crypto assets within an organization's environment, including the algorithms certificates used, their issuers, expiration dates, the domains they protect, and even the software signed with specific keys. Additionally, organizations must investigate whether their software packages or devices automatically download updates, connect to backend servers, or operate on websites or portals managed by third parties or cloud providers. Establishing these details requires extensive communication with various providers and backend entities. While identifying an organization’s digital footprint may seem daunting, it is essential in today’s interconnected world. Understanding crypto assets is the key to protecting them effectively. Step 2: Prioritize The next step involves prioritizing the replacement of encryption algorithms that generate signatures requiring long-term trust. This includes securing the roots of trust, firmware for long-lived devices, and other critical components. The urgency arises from the fact that encrypted data can be recorded now and decrypted later by operators of future quantum computers, a practice known as “harvest now, decrypt later.” Therefore, any encryption intended for long-term use should be the first priority for replacement. Step 3: Test Furthermore, organizations need to explore and test the incorporation of post-quantum cryptography algorithms. The National Institute of Standards and Technology (NIST) has already selected the final algorithms for PQC standardization, but the development of standards, documentation, and secure implementation methods is still underway. It may take up to two years before these algorithms become widespread. However, implementers of cryptographic libraries and security software should start integrating these algorithms into their products now. Organizations can also begin exploring how to incorporate the selected PQC algorithms, as there will be a certain level of effort required to accommodate them. While the deadline for federal agencies to submit their inventories of cryptographic systems has passed, the need for all organizations to identify and manage their crypto assets proactively remains. The transition to quantum-resistant cryptography is a significant undertaking, but by understanding and Cyber Defense eMagazine – August 2023 Edition 118 Copyright © 2023, Cyber Defense Magazine.
