Certificateless ring signcryption scheme
Qi You Xie · Computer Engineering and Applications Journal · 2011
Certificateless public key cryptography resolves the key escrow problem and public key authentication problem.A certificateless ring signcryption scheme which modifies the key generation algorithms of Selvi et al’s ID-based ring signcryption scheme is proposed.In the random oracle model,the scheme is provably secure against adaptive chosen ciphertext attacks.
