The wireless communication with delivering variety of services to users is growing rapidly in recent years. The third generation of cellular networks (3G), and local wireless networks (WLAN) are the two widely used technologies in wireless networks. 3G networks have the capability of covering a vast area; while, WLAN networks provide higher transmission rates with less coverage. Since the two n...

Query-based web search is an integral part of many people’s daily activities. Most do not realize that their search history can be used to identify them (and their interests). In July 2006, AOL released an anonymized search query log of some 600K randomly selected users. While valuable as a research tool, the anonymization was insufficient: individuals were identified from the contents of the q...

background: nepeta menthoides boiss & buhse is a species from lamiaceae family. it is used as a herbal medicine with common name “ostokhodus” in iranian traditional and folk medicine but there is not enough information about its quality and quantity control methods. objective: in this study we use micromorphological and phytochemical evaluations for qualitative and quantitative control of n. me...

We introduce and realize the notion of fully simulatable multiparty computation. Unlike any of the previous models, our notion simultaneously enjoys the following features: • Main feature: The simulator does not have any extra power over the “real-life” adversary. In particular, it cannot program any public parameters or run in super-polynomial time. Thus, our implementation is fully deniable f...

We study simulation-based, selective opening security against chosen-ciphertext attacks (SIM-SO-CCA security) for public key encryption (PKE). In a selective opening, chosen-ciphertext attack (SO-CCA), an adversary has access to a decryption oracle, sees a vector of ciphertexts, adaptively chooses to open some of them, and obtains the corresponding plaintexts and random coins used in the creati...
