If one or more client nodes are connected to the master node, the mobile device authentication is performed as follows.
When a client node is connected to the master node first, the mobile device authentication is performed as follows.
As a result of this authentication, the EAP's keys namely, master session key (MSK) and extended master session key (EMSK) are derived.
The client sends its authentication password, encrypted with the master's public key.
Those schemes require additional authentication server to pre-distribute pairwise master keys (PMK) during a fast re-authentication session.
When completing a full authentication, some authentication-related attributes, such as master key (MK), K_encr, K_auth, and temporary fast re-authentication identity have already been stored in the RADIUS server and in the MS, respectively.
In step A1 of the proposed scheme, U sends a MAC message mac U = MAC key(U ID, sk) as a authentication request to NCC, and then, NCC authenticates U by verifying if U knows/possesses master secret key key.
The KDC also maintains a centralized authentication database containing a copy of every user's master key.
As in many old master paintings, where the hand of the artist becomes a mark of authentication, the signatures on the drawings around the room practically supersede the images themselves, becoming — like Ms. Gangloff's paintings — a collective portrait of the artistic community Mr. Esber inhabits.
On receipt and before freezing a master cell bank (MCB) or seed stock (see Section 1.4), cell line authentication should be performed using an approved DNA-based method (see Sections 1.2.2 and 1.5.1) for confirming the origin of a cell line (American National Standards Institute, 2011; ICLAC, 2013b) and to check for misidentification.
