Post-Quantum Security of Key Encapsulation Mechanism against CCA Attacks with a Single Decapsulation Query
Abstract
Recently, in post-quantum cryptography migration, it has been shown that an IND-1-CCA-secure key encapsulation mechanism (KEM) is required for replacing an ephemeral Diffie-Hellman (DH) in widely-used protocols, e.g., TLS, Signal, and Noise. IND-1-CCA security is a notion similar to the traditional IND-CCA security except that the adversary is restricted to one single decapsulation query. At EUROCRYPT 2022, based on CPA-secure public-key encryption (PKE), Huguenin-Dumittan and Vaudenay presented two IND-1-CCA KEM constructions called
