Question

write a short note on Digital signature

Answer 1

A digital signature or digital signature scheme is a type of asymmetric cryptography. For messages sent through an insecure channel,a good implementation of digital signature algorithm is the one that makes the receiver believe that the message was sent by the claimed sender , and trust the message.
Digital signatures are equivalent to traditional handwritten signatures in many respects: properly implemented digital signatures are more difficult to copy than the handwritten type. Digital signature are implemented using cryptography . Digital signatures can also provide acknowledgement, meaning that the signer cannot successfully claim they did not sign a message , while also claiming their private key remains secret.

Answer 2

DIGITAL PRESENTATION

Digital signature:

A digital signature or digital signature scheme is a mathematical scheme to denote the authenticity of a digital message or document. A valid digital signature assures the recipient that the message was produced by a known sender and was not altered in transit. Digital signatures are commonly used in software distribution, financial transactions, and other such cases where counterfeiting and tampering detection is more important.

Digital signatures are often used to implement electronic signatures, a broad term that refers to any electronic data that accompanies the purpose of a signature, but not the use of a digital signature in all electronic signatures. is done.

In some countries, including the United States and the European Union, electronic signatures have legal significance. However, the laws relating to electronic signatures do not always clarify whether they are used here in the sense of digital seedwriting signatures and, therefore, their importance, to some extent, is misleading, aside from the legal definition.
