ePrint Report: A note on ``a multi-instance cancelable fingerprint biometric based secure session key agreement protocol employing elliptic curve cryptography and a double hash function''

Zhengjun Cao, Lihua Liu

We show that the key agreement scheme [Multim. Tools Appl. 80:799-829, 2021] is flawed. (1) The scheme is a hybrid which piles up various tools such as public key encryption, signature, symmetric key encryption, hash function, cancelable templates from thumb fingerprints, and elliptic curve cryptography. These tools are excessively used because …
