Abstract: According to the principle of the chess game, a new encryption algorithm was developed. Before encrypting the information, process all the original information into two-dimension and establish the original information tables. And then find out 2D coordinate components of the plaintext in the tables, while encrypting. This two-dimensional information will be stored in a corresponding three-dimensional table to form cipher text, according to certain rules. According to the order of the information stored, the encrypted information can be deciphered. This algorithm founds two sets of cipher codes completely independent of each other. With 7 decimal number described in the context of the original information table, taking the 7×7×2 three-dimensional form for example, the algorithm was figured in detail. The algorithm, for the first time, uses two-dimensional digital processing on the information. The principle is easy to understand, in diversified forms, faster, and of less computing, higher security and large number of secret keys.
