Abstract:
Because almost all existing certificateless signature schemes need bilinear pairings either during signature generation stage or the signature verification stage, acertificateless signature scheme without pairings was proposed in this paper. The scheme is provably secure in the random oracle model (ROM) under the discrete logarithm assumption.Furthermore, the efficiency of this scheme is very high,due to its security, high efficiency and freedom from certificate management, the certificateless signature scheme may have practical applications inelectronic commerce and electronic voting, etc.
KeyWords:
certificateless signature scheme； random oracle model； without bilinear pairing
