SNC (Secure Network Communication) Client Encryption is an optional feature for SAP GUI and the SAP NetWeaver technology platform. This software component enables users to protect communications between SAP GUI and the SAP Application Server ABAP using symmetric encryption algorithms.
Please note that licensing restrictions prohibit using this feature to set up single sign-on. Please note that due to licensing restrictions, SNC Client Encryption may not be used in combination with single sign-on technologies (for example logon tickets). SAP NetWeaver Single Sign-On is the recommended solution if you require both communication protection and single sign-on in the same scenario.
For detailed information on SNC Client Encryption, please refer to SAP Note 1643878; for information on SAP's SSO solution, SAP NetWeaver Single Sign-On, visit our SCN space.
