Efficient Verifiably Encrypted Signature Scheme
Weilong Liu · Journal of Chinese Computer Systems · 2010
Based on the Hess signature scheme,an efficient id-based verifiably encrypted signature scheme was proposed.The scheme had the less pairing operations,and adjudicator signed a guarantee to avoid refusing to resume the common signature when resolving conflicts,thereby exchange signature protocol's equity was enhanced.Compared with the other schemes,the proposed scheme was more efficient.At last its security was proved in the random oracle model.The proposed scheme was proved to be secure assuming the computing Diffie-Hellman problem was hard.
