| description | We revisit the SM2 protocol, which is widely used in Chinese
commercial applications and by Chinese government agencies. Although
it is by now standard practice for protocol designers to provide security
proofs in widely accepted security models in order to assure protocol implementers
of their security properties, the SM2 protocol does not have
a proof of security. In this paper, we prove the security of the SM2 protocol
in the widely accepted indistinguishability-based Bellare-Rogaway
model under the elliptic curve discrete logarithm problem (ECDLP)
assumption. We also present a simplified and more efficient version of
the SM2 protocol with an accompanying security proof. |
