WebJan 1, 2024 · Here, we proposed an ECC-based proxy signcryption for IIoT (ECC-PSC-IIoT) in a fog computing environment. The proposed scheme is providing the features of signature and encryption in a single cycle to active the basic requirements of low computation and communication cost. WebSigncryption is a public key cryptographic primitive which provides both privacy and authenticity of data. There exists a vast literature on signcryption in the classical setting. It was originally proposed by Zheng [Zhe97], followed by later works [ADR02, BSZ07, MMS09], which focused on formalizing the security of signcryption and
