The modification of RSA algorithm to adapt fully homomorphic encryption algorithm in cloud computing

RSA is Partially homomorphic cryptosystem, based on the features of the RSA algorithm, we design a encryption system, this encryption system firstly discriminates whether the values of the public key and private key generated during the encryption process contain prime number, then combines with the Pascal's triangle theorem and RSA algorithm model and inductive methods to construct a new cryptosystem that meets homomorphic computation of some operations on cihpertexts(e.g., additions, multiplications), Thus the new cryptosystem satisfies fully homomorphic encryption in cloud computing.
