TAILIEUCHUNG - Lecture Data security and encryption - Lecture 23: Wireless Network Security

The contents of this chapter include all of the following: IEEE Wireless LANs, protocol overview and security, Wireless Application Protocol (WAP), protocol overview, Wireless Transport Layer Security (WTLS). | Data Security and Encryption (CSE348) Lecture slides by Lawrie Brown for “Cryptography and Network Security”, 5/e, by William Stallings, briefly reviewing the text outline from Ch 0, and then presenting the content from Chapter 1 – “Introduction”. Lecture # 23 Review have considered: remote user authentication issues authentication using symmetric encryption the Kerberos trusted key server system authentication using asymmetric encryption federated identity management Chapter 15 summary. Chapter 17 – Wireless Network Security Opening quote. This chapter looks at two important wireless network security schemes. First, we look at the IEEE standard for wireless LAN security. The remainder of the chapter is devoted to security standards for Web access from mobile wireless devices, such as cell phones. IEEE IEEE 802 committee for LAN standards IEEE formed in 1990’s charter to develop a protocol & transmission specifications for wireless LANs (WLANs) since then demand for WLANs, at different frequencies and data rates, has exploded hence seen ever-expanding list of standards issued IEEE 802 is a committee that has developed standards for a wide range of local area networks (LANs). In 1990, the IEEE 802 Committee formed a new working group, IEEE , with a charter to develop a protocol and transmission specifications for wireless LANs (WLANs). Since that time, the demand for WLANs, at different frequencies and data rates, has exploded. Keeping pace with this demand, the IEEE working group has issued an ever-expanding list of standards. IEEE 802 Terminology Stallings Table briefly defines key terms used in the IEEE standard. Wi-Fi Alliance first broadly accepted standard Wireless Ethernet Compatibility Alliance (WECA) industry consortium formed 1999 to assist interoperability of products renamed Wi-Fi (Wireless Fidelity) Alliance created a test suite to certify .
