This paper designed a group signature scheme on conic curve over finite field GF(2n),and made its numerical simulation and performance analysis.The scheme not only has the features of anonymity,unforgeability,traceability and high safety which most of group signature schemes based on conic curve have,but combined the calculation with NAF could also made the multiple group elements operation,which contained high-efficiency double group element operation on conic curve over GF(2n),more efficient.This scheme is more efficient than group signature schemes on conic curve over finite filed Fp,in addition,is promising.
