Erratic Cryptosystem for Elevated Message Security

As the demands for the secure communication grow, cryptographic processing may become a must done situation, in secured message transmission. Random numbers are widely used, especially in cryptography. Any pseudo-random bit stream along with Ex-OR provides a cryptosystem and any good cipher text should look like a pseudo-random bit stream. The proposal of implementing randomization in crypto graphical algorithms is to improve the overall performance by randomizing the standard algorithms and thus to optimize the high-level message security. This paper proposes a cryptosystem that split the message file into different message blocks randomly and then choose the encryption algorithms randomly by using random number generator algorithm (RNGA) for each and every message block, which is also chosen randomly. Also generate the random key by using RNGA for each and every message block. After encrypting all the message blocks, shuffle it using another sequence of random numbers. For decryption, chose the same random numbers and do the reverse process to get the original message file
