An Efficient MQV Key Agreement SchemeKey Agreement Protocol • May 8th, 2014
Contract Type FiledMay 8th, 2014Menezes et al. proposed the first key agreement protocol (MQV) that employs a signature to sign Diffie-Hellman public keys without using a one-way hash function. The IEEE Standard Committee adopted the MQV protocol as a standard. In order to establish multiple common secret keys between two parties, Harn and Lin proposed a new protocol based on the MQV protocol. However, this pro- tocol has a limit that only n2-1 keys out of n2 keys for can be used avoiding the known key attack. Afterwards, Tseng proposed a protocol that can use n keys to avoid the known key attack. In this article, we shall extend Tseng’s protocol and make it able to generate (n2 + 1) keys in one session, and all the keys can be used against the known-key attack.
