چکیده
A secure non-interactive electronic cash system is presented. The system requires no interaction between users.

Firstly we discussed the security model of e-cash schemes based on the blind multisignature scheme against a (restricted) attack model and proposed a concrete scheme proven to be secure in the mod...
