Deniable Encryption Key
Deniable encryption is an important that allows a user (a sender and/or a receiver) to escape a coercion attempted by a coercive adversary. Such an adversary approaches the coerced user after transmission forcing them to reveal all their random inputs used during encryption or decryption. Since traditional encryption schemes commit the user to their random inputs, the user is forced to reveal the true values of all their random inputs (including the encrypted/decrypted messages and the encryption/decryption keys) which are verifiable by this coercer using the intercepted cipher text.
