IMPLEMENTATION OF DIGITAL SIGNATURE ALGORITHM USING BIG DATA

Signcryption techniques combine encryption and digital signature processes to reduce the overhead of doing these steps individually. This is why digital signatures are so important in systems where sensitive data has to be protected. Digital signatures based on elliptic curves may be used to increase application security at cheap cost. Experts are making every effort to make ECDSA more robust so that it can withstand a range of difficulties, despite the fact that it is the most novel of all asymmetric digital signature systems. If the signed message is intercepted and sent, the digital signature will not be able to stop a replay attack. The intruder may even forge the sender's digital signature in order to conceal their true identity. This method is an advancement in cryptography since it combines digital signatures and public encryption into a single system.
