Chapter 9 Encryption Encryption Types Supported in Dell Instant Encryption is the process of converting data into an undecipherable format or code when it is transmitted on a network. Encryption prevents unauthorized use of the data. The following encryption types are supported in Dell Instant: WEP Though WEP is an authentication method, it is also an encryption algorithm where all users typically share the same key.
Understanding WPA and WPA2 The Wi-Fi Alliance created the Wi-Fi Protected Access (WPA) and WPA2 certifications to describe the 802.11i standard. The standard was written to replace WEP, which was found to have numerous security flaws. It was taking longer than expected to complete the standard, so WPA was created based on a draft of 802.11i, which allowed people to move forward quickly to create more secure WLANs. WPA2 encompasses the full implementation of the 802.11i standard.
