Sigsaly and modern E2EE share the same principle: security depends on the weakest link—the generation, distribution, and destruction of keys.

UnverifiedSigsaly's unconditional security depended on the absolute secrecy and one-time use of keys, whereas modern E2EE is mostly based on computational complexity assumptions (such as the difficulty of factoring large numbers) and is not information-theoretically secure.77% similarUnverifiedThe security of E2EE is highly dependent on the quality of key management implementation, including details such as device pairing methods, key derivation algorithms, and whether forward secrecy is supported.73% similarUnverified优雅降级（graceful degradation）与故障安全（fail-safe）是安全关键系统工程中的两个核心设计原则66% similarUnverifiedSigsaly's deployment exposed the contradiction between security and convenience: the equipment was bulky and complex to operate and was restricted to the highest levels, and any encryption system must find a balance between security and usability.66% similarUnverifiedModern E2EE systems rely on asymmetric cryptography (such as Diffie-Hellman key exchange) and digital signatures for key synchronization, whereas Sigsaly achieved key synchronization through the physical distribution of one-time key paper tapes.65% similar
