Comments Off on Key-Aggregate Cryptosystem for Scalable Data Sharing in Cloud Storage
Posted in: IEEE 2017, Java
Key-Aggregate Cryptosystem for Scalable Data Sharing in Cloud Storage Data sharing is an important functionality in cloud storage. In this paper, we show how to securely, efficiently, and flexibly share data with others in cloud storage. We describe new public-keycryptosystems that produce constant-size ciphertexts such that efficient delegation of decryption rights for any set of ciphertexts are possible. The novelty is that one can aggregate any […]

Comments Off on Fast Nearest Neighbor Search with Keywords
Posted in: IEEE 2017, Java
Fast Nearest Neighbor Search with Keywords Conventional spatial queries, such as range search and nearest neighbor retrieval, involve only conditions on objects’ geometric properties. Today, many modern applications call for novel forms of queries that aim to find objects satisfying both a spatial predicate, and a predicate on their associated texts. For example, instead of considering all the restaurants, a nearest neighbor query […]
