"WebThe Digital Signature is a technique which is used to validate the authenticity and integrity of the message. We know that there are four aspects of security: privacy, authentication, integrity, and non-repudiation. We have already discussed the first aspect of security and other three aspects can be achieved by using a digital signature. " - Digital signature schemes in cryptography

WebDigital signature schemes typically use a public-key cryptosystem (such as RSA or ECC) and use a public / private key pairs. A message is signed by a private key and the signature is verified by the corresponding public key: ... RSA signatures are widely used in modern cryptography, e.g. for signing digital certificates to protect Web sites ... WebAnother application in public key cryptography is the digital signature. Digital signature schemes can be used for sender authentication. Non-repudiation systems use digital signatures to ensure that one party cannot successfully dispute its authorship of a document or communication.
