Implementing Digital Signature Based Secured Card System for Online Transactions
The RSA and other allied cryptographic mechanisms are widely used to provide security to the data during any online web based transactions. It has been proved that the Zhang proposed RSA cryptosystem could be easily cracked by an intruder. So, the security of the information in the network is becoming an important aspect in any web based communications. A new mechanism based on RSA to further enhance security is to make use of digital signatures to ensure the receiver that the message was created by a known sender, and that it was not altered in transit.
