Abstract	:	Cryptographic cipher strength, highly depends on the statistical performance of its generated key stream. The generated key stream is constructed stochastically for the statistical behavior of secure key. This enormous behavior proves that the level of security proffered by the cipher. When the key behaves as a random nature, it increases the encryption performance of high-quality key stream. Many key generation techniques use a pseudorandom binary sequence as a key due to its randomness in nature. Keeping with this view, in this paper pseudorandom binary sequence generated key is applied in encryption & decryption of text & images, which is tested by frequency (monobit) test.
