The authors present a new general construction of public key encryption (PKE) based on the restricted subset membership (RSM) assumption, which can achieve the bounded-memory leakage resilient security and the auxiliary-input leakage resilient security simultaneously. The construction is BHHO-type, as Brakerski et al. work, but the message space is much larger and the proof is more concise benefiting...
Hash tree based disk storage integrity protection suffers from performance penalty and possible losing of consistency. FI-Tree deploys a fixed-structure tree and applies incremental-hash to tree node updating to solve the difficulties of performance and consistency. The biggest advantage of FI-Tree comes from that: to allow tree nodes to be cached to optimize performance, it can maintain consistency...
Storage systems are more distributed and more subject to attacks. Cryptographic file system gives a promising way to mitigate the danger of exposing data by using encryption and integrity protection methods and guarantee end-to-end security to clients. This paper describes SRSAE, a generic approach to cryptographic file system, as well as its realization in a distributed data storage environment....
