A Method of Security Gradation against RSA IEA

Along with a rapid growth of cloud computing technology and its deep application in Agriculture Intelligent Information System, Agriculture Industry information security and privacy has become a highlight of the issue about Agriculture Cloud Information System. Encrypting is a conventional information security means, however, hitherto almost all encryption scheme cannot support the operation based on cipher-text. As a result, it is a difficult to build up the corporate and individual information security and privacy-securing in the information system based on cloud computing platform. In order to construct the information security and privacy of cloud computing infrastructure, down to the practicality of Agriculture Information System the project crew brings forward An Innovative Encryption Method for Agriculture Intelligent Information System based on Cloud Computing Platform, OCEVMO for short, which takes root in the theory of matrix, and supports a series of cipher-text-operation essential to build a secure communication protocol between user, owner and cloud server. Beside the conventional encryption-decryption operation, OCEVMO implements 4 operations of cipher-textnumerical-value data such as adding, subtracting, multiplying and dividing. Theoretical analysis and experimental performance estimation demonstrates that OCEVMO is of IND-CCA security, capable of performing crypo-function with a moderate speed. Its favorable versatile performance gives promise of the interactive operation Securing corporateindividual privacy in the area of Agriculture Intelligent Information System.

On purpose to elevate the efficiency of elliptic curve scalar multiplication in the device with weak computation power and to improve computational security, in this paper we pioneer a novel algorithm named Improved-m-ary, which is based on the depth first addition chain scheme and the improved m-ary mechanism compatible with a flexible width window. At first, we research and analyze the advantages of addition-chain-method, m-ary and other algorithms respectively in terms of speeding computation by comparison. It is discovered that the proportion of atomic operation and window width are 2 key factors which keep the speed of scalar multiplication and its computation cost in a leash. Then, an innovative scalar-point-multiplication algorithm is designed by the project crew on the basis of findings of project research. At last, the results of theoretical analysis and experimentation statistics demonstrate that by this algorithm the average of hamming weight of the scalar as a multiplicator could be undercut and the computation cost of point-scalar-multiplication could be lowered to an amazing extent. In addition, because of its built-in scheme whereby the window width is randomized constantly it presents a favorable strong immunity against most attack methods hinged on power analysis .As a whole, it is potential that Improved-m-ary be a practical and promising fast scalar multiplication method alternative.
