【摘要】 提出了一种新的有消息关联的可验证的门限签密方案,其中分工签密技术的应用大大降低了签密者的负担。把消息分成若干可读的消息子块,组内任意t个签密者都可以代表整个组对消息签密。每个签密者只需对自己的消息子块操作即可,因此,其工作量大大减少,而签密速度却明显提高。更多还原

【Abstract】 Anew(t,n) threshold-authenticated encryption scheme with message linkage is proposed.The proposed scheme is based on the ECC(elliptic curve cryptosystem).The total message is divided into a few readable sub-message blocks.Any random t signer can sign the message on behalf of the whole group.Each signer needs to sign the designated sub-message block rather than the whole message.Compared with other scheme,the workload isreduced and performance is improved.更多还原
