Digital signatures have a number of important advantages
DIGITAL SIGNATURE
SECURITY : To guarantee that a digital signature is genuine and that the document has not been altered, robust cryptographic procedures are used. In comparison with conventional handwritten signatures, this offers a high level of security.
AUTHENTICITY : Digital signatures verify the signer’s identity, ensuring that the document was sent to the intended recipient and was not falsified.
INTEGRITY : Digital signatures guarantee the integrity of the document by preventing any alterations made after it is signed.
EFFICIENCY : Digital signatures simplify the signing process and cut down on paperwork by doing away with the need to print, sign, and scan papers.
COST-EFFECTIVE : The expenses of printing, scanning, and keeping paper documents can be greatly decreased by using digital signatures.
LEGALLY BINDING : Digital signatures are accepted in several nations as
The Operation of Digital Signatures
Digital signatures function by generating a distinct digital fingerprint, also known as a hash value, for a communication or document through the use of cryptographic algorithms. The digital signature is then created by encrypting this hash value with the sender’s private key. By comparing the decrypted hash value with a revised hash value of the received message or document, the recipient can confirm the authenticity of the signature by decrypting it using the sender’s public key. It is verified that the sender is real and that the content has not been changed after it was signed if the two hash values match. This procedure ensures the confidentiality and security of electronic transactions and communications.
