services. The terminal may also require SwMi to authenticate, thus making the authentication
mutual
The authentication centre (AuC) manages the assignment, control and distribution of encryption key
information to the (SwMI), and manages keys for Air Interface Encryption and Authentication
services for the Dimetra infrastructure entities.
Note: Authentication and encryption require key storage/provisioning to be functional, to make
these features operational.
Note: The terminal, and SwMi encryption and authentication support are classified into 3 classes:
• Class 1 – no encryption, may use authentication;
• Class 2 – SCK encryption, ESI with SCK, may use authentication;
• Class 3 – DCK encryption, ESI with CCK, authentication.
15.2 MS Mutual Authentication
Enables/disables authentication initiated by SwMi and made mutual by terminal.
The SwMi initiates the process by challenging the terminal to prove its authenticity (“authentication
of the MS…”). The terminal responds with its proof of authenticity and a challenge of its own to the
SwMI (“…made mutual by the MS”).
The authentication centre (AuC) manages the assignment, control and distribution of encryption key
information to the Switching and Management Infrastructure (SwMI), and manages keys for Air
Interface Encryption and Authentication services for the Dimetra infrastructure entities.
Note: Authentication and encryption require key storage/provisioning to be functional, to make
these features operational.
Note: The terminal, and SwMi encryption and authentication support are classified into 3 classes:
• Class 1 – no encryption, may use authentication;
• Class 2 – SCK encryption, ESI with SCK, may use authentication;
• Class 3 – DCK encryption, ESI with CCK, authentication.
15.3 Mandatory Mutual Authentication
If this feature is enabled, it indicates that SwMI authentication is mandatory.
15.4 SCK Air If Encryption
This field contains the Class of MS and the all MS information elements to indicate the infrastructure
the characteristics of the MS terminal support (Authentication-flag, SCK-AI).
15.5 DMO SCK
Indicates if the MS supports DMO SCK feature. DMO SCK is to represent SCKs designated for
secure DMO.
