Efficient Certificateless Compact Sequential Multi-signature Scheme
Yulei Zhang · Jisuanji gongcheng · 2011
A new efficient certificateless compact sequential multi-signature scheme is proposed based on the certificateless public key cryptosystem and bilinear pairing technology.The scheme is compact,the length of signature is fixed,and does not grow with the number of the singer.Meanwhile,the scheme is efficient.In the scheme,the numbers of bilinear pairing is also fixed,and the computation complicacy of signature algorithm or verify algorithm is independent with the singer's number.Furthermore,basing the random oracle,the scheme proves secure against existential forgery under the adaptive chosen message attacks,assuming that the computation Diffie-Hellman problem assumption holds.
