Computer Science - Cryptography and SecurityK.6.MK.6.5G.1.0E.3D.4.6In this thesis, we propose some directed signature schemes. In addition, we have discussed their applications in different situations. In this thesis, we would like to discuss the security aspects during the design process of...
Digital signatures work through public key cryptography's twomutually authenticating cryptographic keys. Forencryptionand decryption, the person who creates the digital signature uses aprivate keyto encrypt signature-related data. The only way to decrypt that data is with the signer's public key. If ...
Digital signatures are one of the most significant achievements of public-key cryptography and constitute a fundamental tool to ensure data authentication. However, the public verifiability of digital signatures may have undesirable cons... Xia,Fubiao 被引量: 2发表: 2013年 Undeniable Signature Scheme...
digital signature (redirected fromDigital signature scheme) Medical Encyclopedia digital signature n. A digital file attached to an email or other electronic document that uses encryption and decryption algorithms to verify the document's origin and contents. ...
Each digital signature consists of two parts: a random component and a signature component. Here’s how each one is produced. To create the random component, a random number is generated and multiplied with a point often referred to as the generator point. In elliptic curve cryptography (ECC)...

(He could, of course, attach his own signature—but that would be like signing the stick up note you hand to the bank teller.) Digital signatures are based on public-key cryptography, which is beyond the scope of this book. However, the basics are important and interesting.[54] In a ...
In this paper, we first present a digital signature scheme using self-certified public key. Subsequently, we present a digital multisignature scheme extended from the proposed digital signature. Both the proposed schemes have the advantage that the authentication of the public key can be accomplished...
