PIN for secure session
A PIN temporarily varies the level of privacy for a secure session. The PIN may be up
to 4 digits long, and is only valid for the current secure session. The same, or a
different PIN, may be used at the next secure session. Every party to the secure session
must use the same PIN for successful secure communication. The PIN may be entered
at the time of going secure, or it may be entered during a secure session to enable a
more private conversation within the Corporate or Global secure mode. Parties must
know what PIN they intend to use without mentioning it over the air.
