Research on the Programming Language for Symmetric Cryptographic Algorithms

The Programming language for symmetric cryptographic algorithms (PLSCA) is proposed. The detailed specification of the syntax of PLSCA is presented, and the cipher of IDEA is described using PLSCA as an example. Using PLSCA, the cryptography designers could describe the structure of symmetric cryptographic algorithms in a formal way, exchange their ideas and algorithm details, test and analyze the symmetric cryptographic algorithms conveniently and rapidly. PLSCA may improve the testing efficiency of new algorithms. It is adapt to assist the design and automatic analysis for symmetric cryptographic algorithms, and it may be used as a standard language to submit new algorithms to the evaluation staff.
