Stolen-Smart Card Attack Sample Clauses

Stolen-Smart Card Attack. Suppose that an attacker steals a legal smart care of a patient and could read the stored parameters {E, P, F, KA-TS/KB-TS,H(), ê() }. The attacker could try to impersonate A or B to successfully login to TS. However, in the proposed protocol, the attacker cannot guess any candidate’s identity and password at the same time and compute V1 and V2. The way for the attacker to learn password is to find out the correct pair (XXX, PWA) such that V2 = H(WA). In the proposed protocol, we assumed the probability of guessing XXX composed of exact l characters and PWA composed of exact m characters is approximately 1/(26l+6m). This probability is negligible, and the attacker has no feasible way to derive XXX and PWA in polynomial time. Xxxxxxx, the proposed protocol is safe from the stolen-smart card attack.
