Abstract

High performance encryption is a key means to minimize security risks as protecting private data in cloud or big data environments. In this paper, a new encryption model SIDA is proposed based on the information dispersal and multi-layer encryption. From theoretical analysis and experiments, it shows that SIDA is secure, can not only significantly improve the speed of data encryption and decryption, but also reduce the bandwidth consumption and re-encryption overhead when revoking authority. Taking SIDA4 algorithm as an example, the encryption speed is about 1.6 times of AES. While the overhead of re-encryption when revoking authority, SIDA4 in communication and computation are 1/4 of AES.
