摘    要:双线性映射作为一种构建密码体制的新工具,在密码学领域中引起了普遍的关注.基于双线性映射提出两种新的多重签名方案,由于多重签名方案是以双线性对为工具构造的,所以密钥长度和签名长度比用其它方法构造的签名要短,该方案的实现是高效的.在CDH和DLP问题的安全假设下,这两种方案是安全的.

关 键 词:双线性映射  数字签名  多重签名  有序多重签名  广播多重签名  双线性映射  签名方案  bilinear  pairing  based  假设  安全  问题  方法构造  长度比  密钥长度  双线性对  密码学  新工具  密码体制

Abstract:As a new technique to construct cryptosystem,bilinear pairing received more attention.Based on bilinear pairing technique,two new multi-signauture schemes are proposed.The new multi-signature schemes have shorter signature length and key length because of the bilinear pairing,and so the new schemes are more efficient.Under the hypothesis of CDH and DLP,the new schemes are secure.
Keywords:bilinear pairing  digital signature  multi-signature  sequential muti-signature  broadcasting multi-signature
