In this paper, we propose data encryption algorithm based on randomized sub blocks XORing of data blocks. The data is divided into number of square blocks (in terms of bits) of equal size. The last block is padded with zeros if required. The proposed algorithm uses pseudo random keys to generate the order of sub blocks of data blocks for encryption. The encryption is done on sub blocks and therefore much faster and highly sensitive for small changes in the keys
