Summary To circumvent using of multiple single servers, the theory of multiserver communication exists and numerous authentication protocols put forward for providing secure communication. Very recently, Amin‐Biswas proposes bilinear pairing–based multiserver scheme by describing some security pitfalls of Hsieh‐Leu protocol and claims that it is secured against related security threats. However, this paper claims that Amin‐Biswas protocol is still susceptible to off‐line identity and password guessing attack, user untraceability attack, and server masquerading attack. The cryptographic protocol should be attacks‐free for real‐time application. To achieve attacks‐free security, we put forward smart card–based multiserver authentication protocol by using the concept of bilinear pairing operation. The formal method strand space model has been used to prove the correctness of the proposed scheme. Additionally, rigorous security analysis ensures pliability of common security threats. The performance and security features of our scheme are also compared with that of the similar existing schemes. The comparison results show that our protocol achieves more security features with less complexity.
