VIBE is “Social by Design” meaning that organizations can set up Trusted Centres (TC) wherein only users or devices registered as members of the TC can communicate with one another. Typically, a TC would be housed in a Hardware Security Module (HSM). Members of one TC can communicate with members of another TC on a permissions/rules basis. Once set up, the TC can be taken offline eliminating the threat of the TC being hacked.
As a use case, an Enterprise like a bank might register all its email users in one TC, and have its clients register in another. With permission, the only email communication that could occur would be from registered or authenticated users. Attempts by outside parties to “phish” within the company’s digital waters would be automatically thwarted as the intended recipient would never receive the nefarious communication.
