How can I access the "security" constant from JSObject?

I would like to set the permissions for printing to "none" using C#.  The Javascript documentation says to use the "security" constant to access like this:

security.getHandler(security.PPKLiteHandler, true);

to access the handler and then to apply the permissions:

this.encryptForRecipients({

oGroups :

[

{userEntities:importantUsers,permissions:{allowAll:true }},

{userEntities: otherUsers, permissions:{allowPrinting:"none"}}

],

bMetaData : true

});

"this" refers to the JSObject, but how do I send the message "security.getHandler"?
