英文摘要： In this project, we shall focus on the key techniques for homomorphic cryptographic primitives in cloud computing. Concretely, our research aims to achieve the following goals. By using our novel tool “reusable garbled gate” which has some strong randomness property, we shall construct new fully homomorphic encryption and new reusable Yao’s garbled circuits and thus establish a new research way in this field. We also want to solve the open problem of constructing fully homomorphic encryption based on classic hard problems or high efficient fully homomorphic encryption scheme. In one word, this project will provide new growth of the design and analysis theory of homomorphic cryptographic primitives, largely broaden their applications and provide a core toolkit for secure cloud data processing.
