摘要：
A (t, n) threshold authenticated encryption scheme allows more than t signers to generate an authenticated cipher-text for a message and only the designated verifier can verify the message. Recently, Chung et al. [1] proposed a (t, n) threshold authenticated encryption scheme by applying a division-of-labor signature technique. However, we showed that the scheme has a design flaw. Then, we proposed a new authenticated encryption scheme based on elliptic curve cryptosystem. The new authenticated encryption scheme is more efficient.
