“SIX Advanced Security Server” is the replacement and renewal of the IBASEC security system currently in use. With the introduction of New Messaging and Security, the IBASEC software is being replaced by the new SASS software and the Safenet LunaSP HSM with the new Swiss HSM Primus S500 from Securosys. Other minor adjustments will also be made to the SIX messaging protocol at the same time.
