Researchers from Nanyang Technological University Report Recent Findings in Data Encryption

May 27, 2014

By a News Reporter-Staff News Editor at Information Technology Newsweekly -- Investigators discuss new findings in Data Encryption. According to news reporting originating in Singapore, Singapore, by VerticalNews journalists, research stated, "Private searching on streaming data is a process to dispatch to a public server a program, which searches streaming sources of data without revealing searching criteria and then sends back a buffer containing the findings. From an Abelian group homomorphic encryption, the searching criteria can be constructed by only simple combinations of keywords, for example, disjunction of keywords."

The news reporters obtained a quote from the research from Nanyang Technological University, "The recent breakthrough in fully homomorphic encryption has allowed us to construct arbitrary searching criteria theoretically. In this paper, we consider a new private query, which searches for documents from streaming data on the basis of keyword frequency, such that the frequency of a keyword is required to be higher or lower than a given threshold. This form of query can help us in finding more relevant documents. Based on the state of the art fully homomorphic encryption techniques, we give disjunctive, conjunctive, and complement constructions for private threshold queries based on keyword frequency. Combining the basic constructions, we further present a generic construction for arbitrary private threshold queries based on keyword frequency."

According to the news reporters, the research concluded: "Our protocols are semantically secure as long as the underlying fully homomorphic encryption scheme is semantically secure."
