Abstract:

Considering that multiple references found that the existing scheme is not efficient, based on reference［5］, it proposes a certificateless proxy blind signature scheme with high efficiency. The scheme is based on the appropriate modification of partial key to reduce the operation time of bilinear pairings. Meanwhile, due to the continuous improvement of the network service, replacing the operation time by the communication time can improve the efficiency. By comparing the proposal with various signature algorithms and verification algorithms, it is proved that our scheme improves the efficiency greatly and satisfies unforgeability, nonrepudiation, identification, blindness, etc.
