In 2013, Dehkordi and Alimoradi proposed a certificateless identification scheme using supersingular elliptic curves. This proposal came independent of the parallel work of Chin et al. in proposing the first known security models for certificateless identification with provable security. In this paper, we show that there are some design flaws in the Dehkordi-Alimoradi scheme, which lead one to conclude that their scheme is insecure.
- Certificateless identification
- Supersingular elliptic curves
