Cryptanalysis of Two-party Explicit Authenticated Key Agreement Protocol
نویسنده
چکیده
In 2015, Zheng et al. proposed an efficient protocol for two-party explicit authenticated key agreement(2EAKA). Zheng et al. claimed that their proposed 2EAKA protocol does not need any fixed public key infrastructure and is provably secure in the random oracle under the Computation Gap Diffie-Hellman assumption. However, this paper points out that Zheng et al.’s 2EAKA protocol still suffers from impersonation attacks based on off-line password guessing attack.

Cryptanalysis of an efficient certificateless two-party authenticated key agreement protocol
Recently, He et al. (Computers and Mathematics with Applications, 2012, 64(6): 1914-1926) proposed a new efficient certificateless two-party authenticated key agreement protocol. They claimed their protocol was provably secure in the extended Canetti-Krawczyk (eCK) model. In this paper, we will show that their protocol is insecure. A type I adversary, who obtains one party’s ephemeral private k...
متن کاملCryptanalysis of Two ID-based Authenticated Key Agreement Protocols from Pairings
Recently, a number of ID-based two-party authenticated key agreement protocols which make of bilinear pairings have been proposed [3, 8, 12, 11, 14]. In this paper, we show that the Xie’s protocol [14] does not provide implicit key authentication and key-compromise impersonation resilience. Also, we point out the vulnerability of the Choi et al’s protocol [3] against signature forgery attacks.
متن کاملCryptanalysis and improvement of two certificateless three-party authenticated key agreement protocols
Recently, two certificateless three-party authenticated key agreement protocols were proposed, and both protocols were claimed they can meet the desirable security properties including forward security, key compromise impersonation resistance and so on. Through cryptanalysis, we show that one neither meets forward security and key compromise impersonation resistance nor resists an attack by an ...
متن کاملCryptanalysis of Efficient Unlinkable Secret Handshakes for Anonymous Communications
Several unlinkable secret handshakes schemes have been proposed in recent years. As performing the successful secret handshakes is essentially equivalent to computing a common key between two interactive members of the same group. Therefore secret handshakes scheme is a key agreement protocol between two members of the same group. So it is necessary for a secret handshakes scheme to fulfill sec...
متن کاملCryptanalysis of Al-Riyami-Paterson's Authenticated Three Party Key Agreement Protocols
Recently, Al-Riyami and Paterson [1] proposed four authenticated tripartite key agreement protocols which make use of Weil pairing. In this paper, we show that the protocols are insecure against the man-in-the middle attack, key compromise impersonation attack and several known-key attacks.
