The probabilistic encryption produces more than one ciphertext for the same plaintext. In this paper an attempt has been made to propose a probabilistic encryption algorithm based on simple linear transformation. The variable length sub key groups are generated using a random sequence. A randomly selected element is replaced by each element of the plaintext from the corresponding indexed sub key group. With this a cryptanalyst cannot encrypt a random plaintext looking for correct ciphertext. The security analysis and performance of the method are studied and presented.
