Towards An Efficient Protocol for Privacy and Authentication in Wireless Networks
نویسندگان
چکیده
We envision a scenario for security of wireless networks that include and integrate nodes of all different capabilities, including tiny sensors or similarly battery-powered, resourceconstrained tiny nodes. However, the existing Wireless Protected Access (WPA) protocol may not be suitable for such resourceconstrained, low-end nodes as the protocol could be too demanding since its existing authentication and privacy mechanisms can cause many inconveniences due their complexity in computation and key management. In this work, we propose an efficient protocol for authentication and privacy in wireless networks using identity-based encryption(IBE) techniques. Specifically, we propose an enhanced or extended version of the WPA protocol by incorporating IBE based authentication methods in the existing WPA protocol at the link layer level. The enhanced WPA protocol can be used for small and resource-constrained wireless devices to integrate them in existing wireless networks. Keywords—Elliptic curve cryptography, identity based encryption, wireless networks

The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against m...

متن کاملAn efficient symmetric polynomial-based key establishment protocol for wireless sensor networks
An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...
