Certificateless Public Key Encryption Scheme with Hybrid Problems and Its Application to Internet of Things

Certificateless cryptography aims at combining the advantages of public key cryptography and identity based cryptography to avoid the certificate management and the key escrow problem. In this paper, we present a novel certificateless public key encryption scheme on the elliptic curve over the ring,...
