This IBM research proposes an intent-based cryptographic API that decouples key creation from specific algorithm identities, significantly enhancing agility for the transition to post-quantum cryptography. By implementing principles like abstraction and temporal flexibility via Protocol Buffers patterns, this design allows organizations to update security algorithms without disruptive application rewrites or extensive code changes. The work directly addresses a critical bottleneck in deploying future-proof cryptographic standards by turning complex migration tasks into manageable operational processes.

IBM Team Designs Intent-Based Cryptographic API for Algorithm Transition

Quantum ZeitgeistJune 15, 20265 min read

Six widely used cryptography APIs, including those from OpenSSL, Java and AWS, currently demand explicit algorithm specification during key creation. This architectural inflexibility hinders migration to newer algorithms essential for post-quantum security and necessitates disruptive code changes across deployments. A new design decouples key creation from algorithm identities, enabling transparent substitution and simplifying cryptographic updates.

A new cryptographic API design, developed by Navaneeth Rameshan and Grégoire Messmer at IBM, addresses software engineering challenges in the transition to post-quantum cryptography. The current cryptographic APIs limit flexibility because of their algorithm-specific design and lack of support for policy-based selection. The design identifies key architectural principles, Abstraction, Stability, Temporal Flexibility, Separation, and Extensibility, and implements them using Protocol Buffers API design patterns. Decoupling key creation from specific algorithms with an intent vocabulary and using stable key identifiers with evolution tracking enables…
