Abstract: In this paper we show that two potential security vulnerabilities exist in the strong password-only authenticated key exchange scheme due to Jablon. Two standardised schemes based on Jablon's scheme, namely the first password-based key agreement mechanism in ISO/IEC FCD 11770-4 and the scheme BPKAS-SPEKE in IEEE P1363.2 also suffer from one or both of these security vulnerabilities. We further show that other password-based key agreement mechanisms, including those in ISO/IEC FCD 11770-4 and IEEE P1363.2, also suffer from these two security vulnerabilities. Finally, we propose means to remove these security vulnerabilities.
