Modern 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.

UnverifiedIn end-to-end encryption (E2EE), each user holds a key pair—the public key is used for encryption and the private key for decryption—and the private key never leaves the user's device.80% 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% similarUnverifiedThe core of envelope encryption is a two-layer key division of responsibilities: the Data Key directly encrypts the actual sensitive data, while the Master Key (KEK, Key Encryption Key) is used to encrypt and decrypt the Data Key.72% similar
