Abstract

Given the importance of cryptography to modern security and privacy solutions, it is surprising how little attention has been given to the problem of \textit{cryptographic agility}, or frameworks enabling the transition from one cryptographic algorithm or implementation to another. In this paper, we argue that traditional notions of cryptographic agility fail to capture the challenges facing modern enterprises that will soon be forced to implement a disruptive migration from today’s public key algorithms (e.g., RSA, ECDH) to quantum-safe alternatives (e.g., CRYSTALS-KYBER). After discussing the challenge of real-world cryptographic transition at scale, we describe our work on enterprise-level cryptographic agility for secure communications based on orchestrated \textit{cryptographic providers}. Our policy-driven approach, prototyped in service mesh, provides a much-needed re-envisioning for cryptographic agility and highlights what’s missing today to enable disruptive cryptographic change at scale.
