HP Deskjet 6800 series printer User's Guide Encryption Definition Encryption involves using a password to encode data sent over a wireless network in order to make the data unintelligible to eavesdroppers. Only devices that know the password can decode the data. Types of encryption The printer supports four types of encryption. Each type of encryption has its benefits and limitations. Encryption type Description Open System Devices on a network do not encrypt data. Benefits Least complicated strategy. WEP encryption Devices on a network share a password, called a "WEP key" to encode and decode Simplest strategy that provides encryption. data. Limitations Provides no protection against eavesdroppers. All devices must have the key. The WEP key does not change automatically. WEP encryption provides less security than both AES or TKIP. 29
