Authenticated Encryption Scheme with Dynamic (t,n) Shared Verification
Lu Jian · Mini-micro Systems · 2004
A new authenticated encryption scheme with dynamic (t,n) shared verification is presented, the security of which is based on the factoring and discrete logarithm problem. While the system's parameter and the secret keys of every user in the scheme are kept unchanged, each user can be either a dealer of message or a message's verifier, and a different message with different threshold value t can be encrypted, hence the scheme is practical. Moreover, the efficient solutions against multiform cheating are proposed, therefore the scheme is highly security.
