INTRODUCTION
Digital signature is a sort of Cryptography. Cryptography means keeping communications private. It is a practical art of converting messages or data into a different form, such that no one read them without having access to the Ëœkeyâ„¢. The message may be converted using a Ëœcodeâ„¢ (in which case each character or group of characters is substituted by an alternative one), or Ëœcipherâ„¢ (in which case the message as a whole is converted, rather than individual characters). It deals with e ....etc

In todayâ„¢s commercial environment, establishing a framework for the authentication of computer-based information requires a familiarity with concepts and professional skills from both the legal and computer security fields. Combining these two disciplines is not an easy task. Concepts from the information security field often correspond only loosely to concepts from the legal field, even in situations where the terminology is similar. For example, from the information security point of view, digital signature means the result of applying ....etc

Abstract:
Signature verification is a technology that can solve security problems in o ur networked
society. A new improved offline signature verification scheme is propo sed which is based on selecting
60 feature points from the geometric centre of the signature and compares them with the already
trained feature points. The classification of the feature points utilizes statistical parameters like mean
and variance. The suggested scheme d iscriminates between two types of ....etc

In paper based financial messaging system, the messages are sent in defined formats duly signed by the authorized signatories. Paperless initiative and changes in the business practices have changed the authorization process. In electronic messaging, the messages are created, authenticated electronically and sent through electronic medium. Present technology facilitates data transmission with security integrity duly taking care of confidentiality and nonrepudiation of messages. Encryption and digital signature play a vital role in providing suc ....etc

A New Forward-Secure Digital Signature Scheme
ABSTRACT
In this paper, the widely used ECC digital signature scheme – ECDSA is advanced, and a new forward-secure digital signature scheme is proposed in order to reform the limitations of ECDSA. In the new scheme, although the digital signature’s private key is under the control of a one-wa ....etc

Digital Signature

Abstract :

The authenticity of many legal, financial, and other documents is determined by the presence or absence of an authorized handwritten signature. The recipient of the signed document can verify the claimed identity of the sender using the signature. Also, if the sender later repudiates the contents of the document, then recipient can use the signature to prove the validity of the document.

With the computerized message systems replacing the physical transport of paper and ink documents, an effective s ....etc
