摘要：Nowadays, the security and privacy protection of Big Data have faced with severe challenges, especially on cloud environment with insecure channel. To address this issue, this paper proposes a security scheme of Big Data identity (SSBDI) for cloud environment, which can guarantee the security of Big Data transmission in the insecure channel. In SSBDI, firstly, linear congruential generator (LCG) based encryption matrixes and Vigenère cipher are employed to set the identity encryption by the client. After that, key bits are added to the end of cipher text in the encryption process. Finally, cipher texts are decrypted and computed in the cloud environment. Innovatively, each key bit can determine the encoding rule of one or more cipher text bits. Experimental results on National Institute of Standards and Technology (NIST) test show that the proposed scheme can meet the randomness of the security requirements. More important, with a very small amount of memory and CPU time cost, the scheme can encrypt massive data, which is particularly significant for Big Data identity encryption. © Springer International Publishing AG 2017.
