By a News Reporter-Staff News Editor at Computer Weekly News -- New research on Cluster Computing is the subject of a report. According to news reporting originating from Guangdong, People's Republic of China, by VerticalNews correspondents, research stated, "Cloud computing is an emerging computing paradigm in which IT resources and capacities are provided as services over the Internet. Promising as it is, this paradigm also brings forth new challenges for security when users want to securely outsource the computation of cryptographic operations to the untrusted cloud servers."
Our news editors obtained a quote from the research from Guangzhou University, "As we know, modular exponentiation is one of the basic operations among most of current cryptosystems. In this paper, we present the generic secure outsourcing schemes enabling users to securely outsource the computations of exponentiations to the untrusted cloud servers. With our techniques, a batch of exponentiations (e.g. t exponentiations) can be efficiently computed by the user with only O(n+t) multiplications, where n is the number of bits of the exponent. Compared with the state-of-the-art algorithm, the proposed schemes are superior in both efficiency and verifiability. Furthermore, there are not any complicated pre-computations on the user side."
According to the news editors, the research concluded: "Finally, the schemes are proved to be secure under the Subset Sum Problem."
