SNC Function Calls 

Use

Secure communication via the CPI-C interface is provided through SAP’s SNC interface (Secure Network Communication).

SNC supports third-party security systems (such as Kerberos, SECUDE, etc.). This provides for a secure Authentification of the partners and secure data transfer.

You can activate the SNC functions via environment variables or entries in the side information file (see the side information basics in the documentation SAP Communication: Configuration).
