- Abstract
On account of the high computational cost of modular exponentiation, the local clients with limited resources can delegate the modular exponentiation to the cloud servers with strong computing capacity. This paper mainly studied the outsourcing algorithm of the modular exponentiation like u" ( mod N), where N is the product of two large prime numbers. The method used Euler theorem to design a new modular exponentiation outsourcing scheme based on two servers model. In the process of computing and outsourcing, it guaranteed the privacy protection of base u, exponent a and calculation results for the two severs. The safety and efficiency analysis and experimental simulation show that compared with the existing schemes, the proposed new scheme has better execution efficiency and verifiability, the efficiency is higher on the client side, and the probability of verifiability of the new scheme is 1.
