“…Security sub-layer architecture [3] Initially, WiMAX security was introduced in the security sub-layer of IEEE 802.16 standard [1]. After releasing the initial versions of the IEEE 802.16 standard, a number of articles such as in [8][9][10] criticized the security weaknesses of the standard, after which some security improvements were added in IEEE 802.16e [3] and IEEE 802.16m [11]. The security functions regarding key managements have been addressed by PKM protocol.…”

“…WiMAX (Worldwide Interoperability for Microwave Access) is also called 802.16 wireless intracity networks or 802.16 [2,3]. WiMAX is an emerging broadband wireless access technology, which can provide high-speed connection for Internet, data transmission farthest distance can be up to 50 km, can offer a broader regional service than Wi-Fi [4].…”

Through the analysis of some security vulnerabilities of WiMAX network and according to the characteristics of the WiMAX network and the research status of intrusion detection, this paper designs and realizes an intrusion detection system based on WiMAX which has the following two features contrast with the existing methods: (1) the full consideration of the vulnerabilities, characteristics and performance of WiMAX network;(2) designs and uses a kind of improved WEP algorithm. Experiments show that this intrusion detection system designed in this paper is only slightly reduced system performance, so it has a very good application value.

“…In [9], the authors pointed out that in the link domain of Mobile WiMAX, the security schemes such as AES-CCM encryption etc are only applied to normal data traffic after initial network entry, and therefore, important messages such as security negotiation parameters in SS Basic Capabilitity (SBC) and security contexts in PKM messages are not protected during initial network entry. The authors also pointed out the access network vulnerabilities due to the fact that the IEEE 802.16e-2005 standard does not cover the security of intra-Access Service Network (intra-ASN) and ASN-to-Connectivity Service Network (ASN-to-CSN) communications.…”

The IEEE 802.16 standard was proposed to provide Broadband Wireless Access for fixed and nomadic subscribers. However, Shon et al [9] identified three vulnerabilities in the existing 802.16 standards. The vulnerabilities are 1) important messages sent during the initial network entry process are not secured in the existing 802.16 standard, 2) there are some Access Network vulnerabilities (the IEEE 802. standard does not cover the security of intra-Access Service Network (intra-ASN) and ASN-to-Connectivity Service Network (ASN-to-CSN) communications) and 3) the HandOver (HO) optimization flags are able to allow malicious users to cause critical security vulnerabilities during the handover process. Shon et al [9] then proposed countermeasures for the above-mentioned vulnerabilities. In this paper, we review Shon et al's countermeasures to initial network entry andAccess Network vulnerabilities and show that their proposed countermeasures are ineffective in preventing attacks to initial network entry and access network communications. We then proposed improved countermeasures that are able to protect against initial network entry and access network communications vulnerabilities.
