Signed Certificate. A certificate that is issued by a certificate authority that guarantees the authenticity of the certificate holder. Static key. A pre-determined security key that is assigned to a device or user for authentication purposes. Subnet. A portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 192.168.0. would typically be part of the same subnet. SSID. Service Set ID, also known as Network name, is a unique identifier used to distinguish one wireless network from another. Wireless devices must use the same SSID to communicate. SSIDs are up to 32 characters long, and are case-sensitive. TCP/IP. The Transmission Control Protocol (TCP) and the Internet Protocol (IP) are protocols that let different types of computers communicate with each other. The Internet is based on this suite of protocols. TKIP. Temporal Key Integrity Protocol, a protocol used with the WPA data encryption mode that scrambles security keys using a hashing algorithm and adds an integrity-checking feature that ensures the keys haven't been tampered with. WEP. Wired Equivalency Protocol, a security protocol defined in the original 802.11b specification that is used to provide data encryption and user authentication. WPA. Wi-Fi Protected Access, a security protocol for wireless networks defined by the Wi-Fi Alliance that was designed to improve upon the WEP security protocol through improved data encryption and user authentication.
