Security in Wireless Data Networks

Abstract

This chapter illustrates the key concepts of security, wireless networks, and security over wireless networks. Wireless security is demonstrated by explaining the main specifications of the common security standards like 802.11 WEP, 802.11 WPA, WPA2 (802.11i) and Bluetooth security standards. Moreover, it explains the concept of WMAN (Wireless Metropolitan Access Network) and its security specifications. Finally, it sums up with thoughts and suggestions about wireless security, along with chosen examples of the current proposals in wireless security.

A privacy‐preserving Blockchain with fine‐grained access control

“…This key derivation scheme is highly efficient: the two hashes that are required to create a venue key can be computed in milliseconds, far faster than the time it would take for Alice to compose any amount of text to post in that venue. AES‐256 encryption is also very fast: over 48 MB/sec in C++ software on a modest Pentium processor (see, for example, a 2006 paper). Thus, the overall performance penalty for Blockchain privacy and access control is clearly negligible.…”

OFDM for Cognitive Radios: An overview Present Solutions and Future Directions

“…General class of threats are similar to those of traditional wireless networks and have been well investigated in the literature e.g. See [50] and the references therein. CRN-specific threats can be attributed to the secondary (or non-prioritized) spectrum access of the CR nodes [49].…”
