Research on combinatorial encryption method

Combinatorial encryption algorithm is advanced. Combinatorial encryption method makes use of the variety of ordinal in universal combination code. Firstly, the theory of universal combinatorial coding is expatiated. Secondly, researches are done in combinatorial encryption characteristic, key generating method, encryption and decryption algorithms. At last, key space is analyzed. Combinatorial encryption technology breaks through the thought of encryption. It is based on combinatorial theory and the code element is adopted as the basic unit in encryption computing. Furthermore, the key generating method is unique. Combinatorial encryption technology makes a new attempt to cipher system.
