Enhanced Performance of Cryptographic Mechanism using Randomized Generation Technique for Secure Transmission of Data

The rapid growth of electronic devices depending on the internet has solved many problems that the humans were facing. The major challenge is “To transmit secure data over the network and to assure its confidentiality, integrity and availability”. The solution is to transfer encrypted data over the network to prevent its unauthorized identification, modification, destruction etc. A new proposed encryption and decryption algorithm has been designed in this paper, in which the data is mathematically scrambled to a form such that the original data is surrounded by a set of randomly generated alphabets. The encrypted format is based on the collection of ASCII codes. This form is used to transfer the data over the insecure network channels.
