If E2EE traffic keys become outdated—which can happen in poor network
coverage conditions—you can manually update them as described here.
Note: Manual key update is not supported on radios which rely on a
Smartcard for E2EE.
Note: During a manual update any active ongoing non-emergency call or
ambience listening calls are cleared.(Any active emergency calls are
maintained.)
Tip: Manual update requires good network conditions.
To manually update E2EE keys
Your radio must be in TMO mode to update E2EE keys.
Either press a suitably customised soft key or use the following procedure:
1. Press Menu then select Security > Crypto Settings.
2. Scroll to New Key and press Send.
When the key update is in progress the Key agreement status icon
appears.
Zeroising
Radios that support End-to-End Encryption are loaded with sensitive
cryptographic keys. To avoid a potential security compromise, you may be
able to delete (zeroise) these cryptographic keys if permitted by your
operational procedures.
Please refer to your Security Officer for details on how to zeroise your radio
as well as related operational procedures.
