A Certificateless Signature Scheme without Random Oracles
Certificateless signature scheme does not require the use of certificates to guarantee the authenticity of public keys as in the conventional public key signature schemes and avoids the problem of key escrow of identify-based signature scheme. Bessie C. Hu et al proposed a new generic construction of certificateless signature scheme. However they did not give a concrete scheme in their model. In this paper,we present a concrete certificateless signature scheme without random oracles in the Bessie C. Hu et aL s model. Our scheme is based on two signature schemes: strongly unforgeable identity-based signature scheme proposed by Chifumi Sato et aL and the Waters signature scheme. Both the schemes are provably secure in the standard model.
