This paper is intended to determine the strength of modern security systems by theoretic approach. The design of existing security system is based on complexity of algorithm and secrecy of key. Besides, several parameters exists that may be useful to determine the strength of cryptosystem. Spurious keys gives text like text as decrypted output to a cryptogram and leads to confusion in proceeding towards unique solution during cryptanalysis. A system rich in spurious keys can be considered as more secured system. This paper presents analysis on stream ciphers and provides a construct model with rich spurious keys. The paper also shows the effect of implementation of Natural Language Model in security system
