Cryptanalysis of Two Password-Authenticated Key Exchange Protocols
نویسندگان
چکیده
In large-scale client-client communication environments, Password-Authenticated Key Exchange (PAKE) based on trusted server is very convenient in key management. For enhancing the efficiency and preventing various attacks, Wang and Mo proposed a three-PAKE protocol, Yoon and Yoo proposed a C2C-PAKE protocol. However, in this paper, we show that the Wang-Mo protocol and the Yoon-Yoo protocol exist impersonation attack.

Cryptanalysis of Two PAKE Protocols for Body Area Networks and Smart Environments
Password-authenticated key exchange (PAKE) protocols enable two or more entities to authenticate each other and share a strong cryptographic key based on a pre-shared human memorable password. In this paper, we present several attacks on two recent elliptic curve-based PAKE protocols that have been suggested for use in body area networks and smart environments. A variant of the first PAKE proto...
متن کاملCryptanalysis of a Three-party Password-based Authenticated Key Exchange Protocol
Key exchange protocols allow two or more parties communicating over a public network to establish a common secret key called a session key. Due to their significance in building a secure communication channel, a number of key exchange protocols have been suggested over the years for a variety of settings. Recently, Lo et al. proposed a three-party password-based authenticated key exchange (3PAK...

Password-Authenticated Key Exchange (PAKE) protocols allow parties to share secret keys in an authentic manner based on an easily memorizable password. Recently, Nam et al. showed that a provably secure three-party passwordbased authenticated key exchange protocol using Weil pairing by Wen et al. is vulnerable to a man-in-the-middle attack. In doing so, Nam et al. showed the flaws in the proof ...
