“…We show our scheme can provide mutual authentication, session key security, known‐key security, and perfect forward secrecy 44 . We also show our scheme can resist the man‐in‐the‐middle attack, the derivation of the signer's private key, the key‐compromise impersonation attack 30,42,44‐46 . The detailed security analysis is described in following subsections.…”

“…In 2011, Junru 41 has also suggested an enhanced scheme to reduce the computational time of ECDSA tout while keeping the same security level of the standard ECDSA. In 2016, Chande and Lee 42 suggested an improvement in Junru ECDSA 41 following the same principal of Liao and Shen ECDSA 40 to reduce the risk of exposure of the private key by an adversary. In 2019, Mehibel and Hamadouche 43 analyzed the variants proposed in the literature, and proposed a new improvement technique for ECDSA of Liao and Shen and ECDSA of Chande and Lee by introducing the unknown parameters used during the verification of the signature.…”

Elliptic curve Diffie‐Hellman (ECDH) scheme is the basic key exchange used in elliptic curve cryptography. ECDH is a public key cryptosystem based on the discrete logarithm problem, but is vulnerable to man‐in‐the‐middle attack because it does not authenticate the secret session key. The integration of the elliptic curve digital signature allows authenticating the secret session key of the ECDH scheme (A‐ECDH). However, it is a technique (A‐ECDH) that uses a single random variable and it has been shown in the literature that a single random variable does not make the system secure. Therefore, the use of two random variables has been suggested to secure an authentication scheme. In this paper, a new authentication scheme using the elliptic curve digital signature algorithm is proposed. The performance analysis of the proposed authentication protocol is performed. The comparative results from the perspective of security and computation time showed that the proposed authentication protocol is more efficient in terms of computation time compared to the related works and it provides all the security features.
