| Summary: | A kind of new distributed signcryption protocol was proposed based on the ideal vector space secret sharing scheme and the modified signcryption scheme of Zheng1.Without the involvement of a trusted key distribution center, this protocol could gain its ends of both threshold signature and threshold encryption simultaneously, however, its cost was equal to threshold signature only.Furthermore, based on the discrete logarithm, properties were verified and structured, the legitimacy of the participators could be confirmed during the processes of the keys generation, distributed signcryption and distributed unsigncryption, which prevented the participators cheating. |
