【摘要】 基于RSA和哈希函数求逆的困难性给出了两种多重数字签名方案,一种是可验证的按序数字多重签名,另一种是广播数字签名。在该两种方案中签名的长度不随签名者的人数线性增长,并且能够抵制各种勾结,具有计算量少、通信量低等特点。更多还原

【Abstract】 We propose two digital multi-signature schemes based on difficulty of RSA and hash fimction. One is a verifiably sequential multi-signature ,the other is a broadcasting multi-signature. The size of signature don’t increase with signer number in those two schemes. The two schemes can resist coalition and have advantages of less computation and communication and so on.更多还原
