1. First, computers have circuits for performing arithmetic operations, such as : addition , subtraction, division, multiplication and exponentiation. 第一，计算机具有进行加、、、及取幂等各种算术运算的电路。
2. Modular exponentiation of larger-number has universal application in cryptography, and it is the base operation in most public-key cryptography algorithms. 大数模幂在密码学领域有广泛的应用，它是公钥密码的基础。
3. In order to prevent sub-secret transmitting in public channel, this paper proposes a secret sharing scheme based on intractability of discrete logarithm and commutativity of modular exponentiation. 为防止子秘密在公开信道中传输，基于离散对数的难解性和模指数函数的可交换性，提出一种秘密共享方案。
