Field Authentication Type Description Type of authentication in use: ● Open System (ad-hoc and infrastructure): no authentication. ● Shared Key (infrastructure only): WEP key is required. ● WPA-PSK (infrastructure only): WPA with Pre-Shared Key. Authentication verifies the identity of a user or device before granting access to the network, making it more difficult for unauthorized users to access network resources. This security method is common on wireless networks. A network using Open System authentication does not screen network users based on their identities. Any wireless user can have access from the network. However, such a network might use WEP (Wired Equivalent Privacy) encryption to provide a first level of security against unauthorized users. A network using Shared Key authentication provides increased security by requiring users or devices to identify themselves with a static key, which is a hexidecimal or alphanumeric string. This key is shared by all users of the network-that is, every user or device uses the same key. WEP encryption is used along with shared key authentication, using the same key for both authentication and encryption. A network using WPA-PSK authentication provides significantly stronger security. It uses dynamically changing encryption keys through WPA (TKIP). Encryption Type Note Open systems shared key or WPA/PSK authentication is entered using the embedded Web server. The type of encryption in use on the network: ● None: no encryption is in use. ● 64-bit WEP: a 5-character or 10-hex-digit WEP key is in use. ● 128-bit WEP: a 13-character or 26-hex-digit WEP key is in use. ● Dynamic: dynamic encryption is being used with WEP, TKIP, or both. WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another. This security method is common on wireless networks. 14 2 Support information for installing to a wireless network ENWW
