Flaws of a Password-Based Three-Party Authenticated Key Agreement Protocol in Post-quantum Environment
摘要
Recently, Islam and Basu presented a password-based three-party authenticated key agreement protocol for mobile devices in post-quantum environment and claimed that the protocol is resistant to several attacks in order to satisfy the demands of three-party communication secure. After examining Islam and Basu’s protocol, we find that the PB-3PAKA protocol is vulnerable to dishonest user’s attack, signal leakage attack (SLA).
