With the rapid proliferation of RFID-based applications, RFID tags have been deployed into pervasive spaces in increasingly large numbers, e.g., the shelves of super markets are filled with tag-labeled items. Conventional localization schemes usually leverage precise anchor nodes to help compute the position of objects. However, it is usually difficult to find or deploy enough anchor nodes for accurate...
Secure wireless communication is a challenging problem due to the shared nature of the wireless medium and the dynamic channel. Most of the existing security mechanisms focus on traditional cryptographic schemes. In recent years, features of multi-path channels, such as randomness, coherence and reciprocity, have driven researchers to exploit their potential to enhance the security of mobile wireless...
Delegation is an important means in modern offices system. In some case, we need to control the verification of a proxy signature, since it is not necessary for anyone to be convinced a justification of signer's dishonorable message such as a bill. In the paper, to realize verification's control and proxy signature's revocation, we put forth a new primitive: controllable proxy signature scheme with...
According to the security features of WiMAX-based wireless communication network, a fresh new wireless communication authentication protocol called WCAP was advanced and designed adopting the dual-key authentication scheme based on trusted third party; its security was analyzed by two means of technical realization and formal analysis; the protocol was implemented by devising an integrated security...
