一种理想格上高效盲签名方案.

In order to protect users’ privacy better and make signatures resistant to quantum attack, a secure and efficient blind signature scheme on ideal lattice was proposed using the rejection sampling theorem and the relationship between high and low order bits. This blind signature function can be achieved through simple calculations without trapdoor functions. the security of the scheme is based on Short Integer Solution(ISISn,m,q,η(s)) assumption, and this scheme has the characteristics of blindness and one-more(OM) unforgeability. Besides, the public and private keys are short and the signature length is only llodq. In general, the scheme is efficient and safe. [ABSTRACT FROM AUTHOR]
