基于旋转矩阵的加密解密算法

Encryption and Decryption Algorithm Based on Rotation Matrix

利用舍入误差分析的方法及计算机浮点运算的特性,构造一种基于旋转矩阵的加密解密算法,并提出了保证算法有效的充分条件.应用实例验证了算法的可行性.

Using the method of round-off error analysis and the characteristics of computer-floating-point operation,we constructed a new kind of encryption and decryption algorithm based on rotation matrix. Then we proposed sufficient conditions for the validity of the algorithm. Finally,we used some numerical examples to verify the feasibility of the algorithm.
