Hybrid Algorithm for E-commerce Applications

Encryption is the processes of converting plaintext message (human readable form of message) to cipher text (scrambled form of message) while decryption is the reverse process of encryption. There are specialized algorithms used to handle the encryption/decryption process in e-commerce applications such as CRYPTON, DES, CAST and others. The chief algorithm used in the E-commerce applications for decoding and encoding large volumes of data is the RSA algorithm because of its level of security. Despite its use its major drawback is that of speed. The algorithm is slow in both encryption and decryption process and therefore could not cope up with large volumes of data. With that that problem in mind a hybrid algorithm was designed by harmonizing AES and RSA with the hope that the weaknesses of RSA will be offset by AES and vice versa.
