HYBRID APPROACH USING ENCRYPTION ALGORITHMS FOR DATA STORAGE

Cryptography is an art and science of converting original message into non readable form. Fast progression of digital data exchange in electronic way, information security is becoming much more important in data storage and transmission. Cryptography has come up as a solution which plays a vital role in information security system against malicious attacks. In this paper author presents HYBRID encryption system for security. Author used Three algorithms in this paper. Caesar cipher is a monoalphabetic cipher which substitute with another character. Rijndael Algorithm uses block length at 128 bits and key sizes of 128, 192 or 256 bits. Vernam cipher (or one-time pad) has played an important rule in cryptography. The key is at least as long as the message. The key is truly random. Each key is used only once, and both sender and receiver must destroy their key after use
