Appendix B - Wireless Technology

Although the calculations required to encrypt data with WEP can impact the performance of your wireless network, it's generally seen only when running benchmarks, and not large enough to be noticeable in the course of normal network usage.

Terminology

802.1x

IEEE 802.1x is an IEEE standard that is built on the Internet standard EAP (Extensible Authentication Protocol). 802.1x is a standard for passing EAP messages over either a wired or wireless LAN. Additionally, 802.1x is also responsible for communicating the method with which WAPs and wireless users can share and change encryption keys. This continuous key change helps resolve any major security vulnerabilities native to WEP.

AES

Short for Advanced Encryption Standard, is a cipher currently approved by the NSA to protect US Government documents classified as Top Secret. The AES cipher is the first cipher protecting Top Secret information available to the general public.

CERTIFICATES (CA)

A certificate can have many forms, but at the most basic level, a certificate is an identity combined with a public key, and then signed by a certification authority. The certificate authority (CA) is a trusted external third party which "signs" or validates the certificate. When a certificate has been signed, it gains some cryptographic properties. AMX supports the following security certificates within three different formats:

-PEM (Privacy Enhanced Mail)

-DER (Distinguished Encoding Rules)

-PKCS12 (Public Key Cryptography Standard #12)

Typical certificate information can include the following items:

-Certificate Issue Date

-Extensions

-Issuer

-Public Key

-Serial Number

-Signature Algorithm

-User

-Version

MIC

Short for Message Integrity Check, prevents forged packets from being sent. Through WEP it was possible to alter a packet whose content was known even if it had not been decrypted.
