| system PSE (BC-SEC) |
Personal Security Environment (PSE) for the SAP System.
The system PSE is created during the system's installation process and contains the system's security information (for example, the public and private key pair).
In Release 4.5A, each application server receives its own system PSE, and as of Release 4.5B, the system creates a single system PSE and distributes it to all of the application servers.
