With the massive development in the technology, this era is witnessing tremendous use of Internet . Huge amount of confidential data trasfer is taking place through Internet. The consequence of this growth is the great demand for data security. Privacy is the most sorted topic in Information Security. The protection of privacy of data can be achieved by the application of cryptography. In this paper a new encryption algorithm is proposed using the simplest classical Caesar Cipher with Linear Congruential Generator for shift size followed by permutation of the words of the message. The strength of the algorithm is ease of use and large key space making Brute force cryptanalysis impossible.
