We revisit Shin et al.’s leakage-resilient password-based authenticated key establishment protocol (LR-AKEP) and the security model used to prove the security of LR-AKEP. By refining the Leak oracle in the security model, we show that LR-AKE (1) can, in fact, achieve a stronger notion of leakage-resilience than initially claimed and (2) also achieve an additional feature of traceability, not previously mentioned.
