Juergen- Interesting. Sounds like a recent development. Reading the blurb on the Cadence web page I get the impression that the solution is vendor specific (some chip vendors may support the capability and some may not). So it seems it is a two pronged solution as I understand it: 1) you must be using devices from a vendor that also uses both Hspice and SQ and chooses to use the new design kit. 2) then you need to have a licensed copy of Hspice that SQ can utilize as an optional simulation engine. While there are a number of 'ifs' that must be satisfied, it sounds that at least there is a path for utilizing the encrypted models.
