新的可验证数字签名托管方案

Verifiable escrowed signatures

使用可验证数字签名共享方案的思想 ,提出可验证数字签名的托管方案 .该方案可以适用于多种数字签名 ,其中对RSA和Rabin签名方案的可验证数字签名的托管方案简单高效 ,更实用 .

The verifiable escrowed signature plays an important role in fair exchange protocol such as contact signing. Based on verifiable signature sharing, we present new verifiable escrowed signatures, which can be applied to many signature schemes. In particular, for RSA and Rabin signatures our schemes are simpler, more efficient and practical.
