メッセージングの耐量子暗号とは何か、いつ重要になるのか?
PQCと「今保存し、将来復号する」脅威を理解し、アルゴリズム、プロトコル、製品の安全性の主張を区別します。
Post-quantum messaging guides covering ML-KEM-768, hybrid keys, FIPS 203, offline prekeys and performance trade-offs.
Quantum-related security claims deserve careful questions. This collection looks at hybrid key agreement, ML-KEM-768 and what post-quantum cryptography means in the everyday design of a messenger.
Explore offline prekeys, group-key distribution, algorithm choices and Android performance. The articles distinguish a cryptographic primitive from the complete system around it.
