Practical Challenges with AES-GCM and the Need for a New Cipher

October 3, 2023


Panos Kampanakis - AWS


AWS is pleased to see the Third NIST Workshop on Block Cipher Modes of Operation 2023 which plans to address limitations of block cipher modes (SP 800-38 series). We also welcome NIST's interest in discussing wide-block encryption techniques.

AWS has a few cloud encryption use-cases that could benefit from efficient new wide-block ciphers and new quantum-safe key transport techniques. This submission presents some of these use-cases and tries to explain the challenges in detail
