In recent years, researchers have proposed several secure device pairing schemes that allow mobile devices in close proximity to establish a trusted communication channel between them without sharing any secret in advance. These schemes use the correlation of some physical measurements (magnetic field, acceleration, etc.,) made independently by the two pairing devices to reconcile them. Their security...
Smart grid is a critical power infrastructure which includes many networked field devices such as Programmable Logic Controller (PLC), Remote Terminal Unit (RTU), status sensors, and smart meters. Securing the smart grid is complex yet essential for our daily lives. This paper presents security protocols for securing the communication, control and management in smart grids. Specifically, it presents...
In social networking, the users' friends are dynamically distributed all over the world and served by many nontrusted and independent providers, thus it is hard to explicitly set-up their public keys with the conventional Public Key Infrastructure so as to provide secure social networking. The present paper aims to build transparently secure channels for social networking. It employs identity-based...
A DCS (distributed control system) optimization approach introducing advanced algorithm realized in MATLAB into the control configuration was proposed. UDP and Modbus/TCP protocol communication program was written to establish two way data communication between the EDPF-NT plus DCS and MATLAB. Two timer objects in MATLAB were used to ensure real-time transmission of the data. Independence and reliability...
Metadata in a parallel distributed database contains information about table fragmentation, physical storage distribution, and access control policies. It is essential to query processing and security policy enforcement. Metadata in a parallel distributed database is usually stored in the form of system tables, it can be replicated through out every site in the system in order to improve performance...
Unlike most of the spams targeting for advertisements only, phishing spams try to cheat the email recipients with bogus sender addresses so as to obtain confidential information of the recipients. This paper presents a Sender Authentication Protocol (SAP) which aims to filter out this kind of crafty spoofing emails. To this end, SAP challenges the claimed-sender with the historical emails so as to...
