Question: In the derivation of a WLCP (Wireless Local Area Network Client Provisioning) key from an EAP (Extensible Authentication Protocol) Master Session Key (EMSK), what is the specified value for the 'P0' parameter used to form the input S to the Key Derivation Function (KDF)?
Option 1: wlcp-auth (0x77 0x6C 0x63 0x70 0x2D 0x61 0x75 0x74 0x68)
Option 2: emsk-key (0x65 0x6D 0x73 0x6B 0x2D 0x6B 0x65 0x79)
Option 3: wlcp-key (0x77 0x6C 0x63 0x70 0x2D 0x6B 0x65 0x79)
Option 4: kdf-input (0x6B 0x64 0x66 0x2D 0x69 0x6E 0x70 0x75 0x74)
Explanation: The correct derivation of a WLCP key from an EMSK requires precise parameters to ensure secure key generation. The 'P0' parameter is set to "wlcp-key" (hex: 0x77 0x6C 0x63 0x70 0x2D 0x6B 0x65 0x79) to correctly form the input S for the Key Derivation Function, highlighting the importance of exact parameter specification in securing wireless communications.
