A Hyperelliptic Curve Cryptosystem Based Proxy Promised Signcryption Scheme
Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 Signcryption is the method of combining a digital signature with encryption in a single logical step to get the cryptographic primitives of a public key. However, in addition to signcryption, we sometimes require anonymity and delegation of rights. In this paper, we propose a scheme called proxy promised signcryption to address all of these objectives ...
