Description: The Password used for PS to derive WPA PSK encryption key. After a successful set, the values of cabhPsDev802dot11SecWPAPreSharedKey is updated as described below:

For wpaPSK: If cabhPsDev802dot11SecOperMode wpaPSK bit is set to '1' the value of cabhPsDev802dot11SecWPAPreSharedKey is updated with the Password Base Key Derivation Function from the Password-based Cryptographic Specification PKCS #5 v2.0 RFC 2898 (PBKDF2) with the following specific parameters:

PSK = PBKDF2(PassPhrase, ssid, ssidLength, 4096, 256) PassPhrase is the value of this object ssid is the PS SSID value used as the function salt ssidLength is the number of octets of ssid the iterations count is 4096 and the key generation length is 256 bits (32 octets).

This object value is normally read by issuing SNMP request PDUs. This object can be cleared with an SNMP SET to an empty string Value and the PS MUST not update the type of keys being set to '1' in cabhPsDev802dot11SecOperMode.

Vector examples for wpaPSK:

for wpaPSK: passphrase: 'ABCD4321' ( hex code 0x41.42.43.44.34.33.32.31 ) SSID: 'ABCD4321' ( hex code 0x41.42.43.44.34.33.32.31 )

256 bit PBKDF2('ABCD4321', 'ABCD4321', 8, 4096, 32) cabhPsDev802dot11SecWPAPreSharedKey = 0x7C199CF2FEF9AF206C8EE0E9703920C2 3517068B3F96B011E0F975C9131BDB58
