摘要: This paper proposes new efficient and secure three-party token-based authenticated key establishment (3TAKE) protocols based on symmetric cryptosystem to minimize the complexity of encryption/decryption operation among all users fit communication. In 3TAKE, number exponentiations three parties is same or reduced by about 34 - 60% operations 67% compared with related protocols, respectively. Furthermore, rounds one round smaller than asymmetric do not need establish a session authenticate between two server.
