Lattice-Based Revocable Certificateless Signature
Symmetry, 2017 Certificateless signatures (CLS) are noticeable because they may resolve the key escrow problem in ID-based signatures and break away the management problem regarding certificate in conventional signatures. However, the security of the mostly previous CLS schemes relies on the difficulty of solving discrete logarithm or large integer factorization ...

Certificateless Generalized Signcryption
Physics Procedia, 2012 AbstractGeneralized Signcryption is a fresh cryptographic primitive that not only can obtain encryption and signature in a single operation, but also provide encryption or signature model alone when needed. This paper proposed a formal definition of certificateless generalized signcryption(CLGSC), then provide the security model of CLGSC.

Timed-Release Certificateless Encryption [PDF]
International Journal of Advanced Computer Science and Applications, 2015 Timed-Release Encryption(TRE) is an encryption mechanism that allows a receiver to decrypt a ciphertext only after the time that a sender designates. In this paper, we propose the notion of Timed-Release Certificateless Encryption(TRCLE), and define its security models.
