Can VT be reverse engineered?
The security of VT is not based on the secrecy of its principles or implementation, but only on the fact that the token can keep small amounts of data and computations secret. Validy uses secure chips from established silicon vendors to ensure that the token is extremely difficult to pry into. Modern secure chips are protected against the latest physical and logical attacks like Side Channel Attacks or Fault Injection. More countermeasures are added to each new generation of chips. Validy is going to work with independent certification agencies to have the complete solution certified. Security conscious customers are also welcome to audit the solution.
