CertificateLess Public Key Cryptography (CLPKC), with properties of no key escrow and no certificate, has received a lot of attention since its invention. However, membership revocation in certificateless cryptosystem still remains a non-trivial problem: the existing solutions are not practical for use due to either a costly mediator or enormous computation (secret channel). In this paper, the authors present a new approach to revocation in CLPKC with a concrete construction of a Revocable CertificateLess Signature (RCLS) scheme.
