Abstract:

Most of the traditional block cipher modes cannot be applied effectively on GPU. We study the traditional encryption models and put forward a packet encryption model cipher,called block random link encryption mode (RCBC),which is efficient,safe and meets parallel computing requirements.This model has a high efficiency,and increases the difficulty of decryption at the same time.Experimental results show that the proposed encryption algorithm has efficient processing ability on CPU_GPU.
