SCK (Air Interface Encryption Class 2)
SCK (Static Cipher Key) is a secret key used for the Air Interface Encryption Class 2. It may be used to
encrypt calls and data in TMO and DMO. The SCK air interface encryption provides service
confidentiality between radios and infrastructure when in TMO, and between radios when in DMO. A
radio is capable of being loaded with up to 32 SCKs. Specific keys are used for encrypting the air
interface.
Any mismatch between radios and/or infrastructure impacts communication – only those using the
same key as the transmitting party are able to decode and hear the communication.
TMO SCK
Use of SCKs in TMO needs to be enabled by your service provider. The SCKs used in TMO are called
TMSCKs.
DMO SCK
Use of SCKs in DMO needs to be enabled by your service provider. The SCKs used in DMO are called
DMSCKs.

• No — to leave the key. Your radio displays Code Not Changed.
Verifying TMSCK Validity
When and where to use: To ensure that the TMSCKs in the radio are valid and can be used for the
air interface encryption.
Procedure:
1 From the home screen, press the MENU key.
2 Select Security → TMSCK Validity.
3 The radio displays:
• TMSCK is Valid – the radio can work encrypted in TMO.
• TMSCK is Invalid – the radio cannot work encrypted in TMO. Please contact your service
provider to restore SCKs to your radio.
