Why does the SafeGuard LAN Crypt user need to be in possession of the public key of the SafeGuard LAN Crypt Administrator certificate?
The encryption rules in the encryption profile are cryptographically signed with the private key of a SafeGuard LAN Crypt security officer. For verification of this signature the SO certificate (containing the public key) is required.
This guarantees that the encryption rules cannot be modified, because the signature would not match.
