Abstract:

The article describes the technology of homomorphic encryption allowing to make calculations over the cipher data without deciphering and distorting them. During the work with cloud storages it is necessary to make calculations with personal data, for example, during the process of online payments, search services and Internet banking. Difficult algorithms are carried out during such work, each of them is the sequence of mathematical operations over data. It requires to decrypt, to process data, and then to cipher these data again. It demands adherence to necessary procedures to storage and transfer a private key. The article introduces modern approaches to the organization of data protection in cloud computing on the basis of cryptographic methods, the algorithm of full homomorphic enciphering by Henry Craig, carrying-out of the program of full homomorphic enciphering in cloud storage according to the algorithm by Henry Craig and performance evaluation of the realized algorithm by Henry Craig.
