The purpose of this entry is to survey the main approaches based on that formula, each of which can be referred to as an RSA digital signature scheme (see also digital signature schemes for general definitions). In the definition just given, the value m is itself the message. This is ...

hence it may be used directly as a digital signature scheme given an RSA scheme {(e,R), (d,p,q)} to sign a message M, compute: S = M power d (mod R) to verify a signature, compute: M = S power e(mod R) = M power e.d(mod R) = M(mod R) RSA can be used both fo...

This paper describes a " digital signature scheme giving message recovery " in order to submit it to the public scrutiny of IACR (the International Association for Cryptologic Research). This scheme is currently prepared by Subcommittee ... LC Guillou,JJ Quisquater,M Walker,... - Workshop on ...
undeniable signatureIn order to resolve the problem of the non-repudiation of digital signatures, this paper analyzes the RSA signature scheme and the undeniable signature scheme, based on this an improved undeniable signature algorithm and the confirmation protocol using the legitimacy of the signature...
We experiment with efficiency of RSA signature in cloud computing. As a result, our scheme can reduce the loading of computing; besides, the clients don't need to waste storage spaces to save the results. The most important of all, we can take full advantage of the cloud computing for ...
A threshold signature scheme is not only a threshold scheme, but also a signature scheme. Therefore, it should possess the properties of both threshold scheme and digital signature scheme. In this paper, we investigate conspiracy attacks on the Desmedt and Frankel's threshold RSA signature scheme...
Digital Signature Standard (DSS) and adopted as FIPS 186 in 1993. DSA is a variant of the ElGamal Signature Scheme. 1. 2. 3. 4. 5. 6. 7. DSA是ElGamal签名方案的变种,被美国NIST作为DSS(DigitalSignature Standard)。其安全性依赖于离散对数难题的,这里不作扩展,仅从应用入手,有兴趣可以自学Jonatha...
