Hiding memory access patterns is required for secure computation, but remains prohibitively expensive for many interesting applications. Prior work has either developed custom algorithms that minimize the need for data-dependant memory access, or proposed the use of Oblivious RAM (ORAM) to provide a general-purpose solution. However, most ORAMs are designed for client-server scenarios, and provide...
As one of the most popular anonymous communication systems, Tor has become a research hotspot in this area. Recently, Tor nodes from Tor families (referred to as family nodes) have played an increasingly important role and caused significant influence on the Tor network. However, existing research about Tor mostly focuses on the entire Tor network without much consideration about the difference between...
Fast-flux based service network is first introduced as a technique used to improve the reliability and quality of a service system. But recently, this technique is also adopted by cyber-criminals and Internet miscreants to evade identification and to frustrate law enforcement and anticrime efforts aimed at locating and shutting down the illegal service. Previous work on this topic focuses mostly on...
According to the features of the distributed application service fault management, we propose a hybrid fault propagation model for fault detection, which includes a multi-layer FPM model and a two-layer FPM model. And the diagnosis process is divided into two procedures: application service fault diagnosis and network service fault diagnosis. Because the observation of faults is uncertain, we map...
A new SIP event package called information-category is proposed based on the SIP event notification framework. With this event package an information sharing service is provided in IMS with SIP signaling. The end user could subscribe to interested information categories with SUBSCRIBE, get information from information sharing application server with NOTIFY, and post information with PUBLISH message...
