Sigsaly'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.

UnverifiedSigsaly and modern E2EE share the same principle: security depends on the weakest link—the generation, distribution, and destruction of keys.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.76% 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.74% similarVerifiedKerckhoffs's principle holds that the strength of a secure system should not depend on the secrecy of its design, but on the secrecy of the key.74% similarUnverifiedThe security of modern cryptographic systems is built on the assumption that certain mathematical problems are 'computationally infeasible,' such as large integer factorization and discrete logarithm solving.71% similar
