We introduce TinySec, the first fully-implemented link layer security architecture for wireless sensor networks. In our design, we leverage recent lessons learned from design vulnerabilities in security protocols for other wireless networks such as 802.11b and GSM. Conventional security protocols

immune systems distinguish self from other. Such "artificial immune systems" would have richer notions of identity and protection than those afforded by current operating systems, and they could provide a layer of general-purpose protection to augment current computer security systems

problems in RFID systems by designing a naive security layer based on authentication and encryption algorithms. The authentication mechanism is the mutual authentication based on a three-way handshaking model, which authenticates both the reader and the tag in the communication protocol. The cipher

The 802.11 standard for wireless networks includes a Wired Equivalent Privacy (WEP) protocol, used to protect link-layer communications from eavesdropping and other attacks. We have discovered several serious security flaws in the protocol, stemming from misapplication of cryptographic primitives

Abstract. Network security problems have been well known and addressed in the application, transport, or network layers. However, the Data Link Layer (Layer 2) security has not been adequately addressed yet. To secure Local or Metropolitan Area Networks, the IEEE 802.1AE Media Access Control (MAC
