The question is: What if these keys were embedded in the processor itself?
It is only natural for the industry to attempt to combine the trusted hardware into the main processor -- that will enhance the value of the hardware and make strong authentication part of the mainstream industry. The growth of applications that require strong authentication and the growth of e-commerce and other applications that handle sensitive data will perhaps make these feature very important additions to the standard “faster, better, cheaper” way of the growth of the processor industry.
A couple of issues about trust models: First, we should avoid the full flexibility that we did in the browser world since its beginning. A good number of the weaknesses of the current e-commerce environment can be avoided if we prevent “suspect” CAs from being trusted at the root, for example.
Second, we don't want to swing the pendulum the other way completely and create monopolies. Instead, we should embark on designing a good system that will allow us to build this industry correctly. Allowing a trusted CA to be a part of the system should be easy to do, assuming that we know how to revoke a CA key and that revocation checking is a standard part of all operations -- all standard operations.
Recognized in the industry as the "inventor of SSL," Dr. Taher Elgamal led the SSL efforts at Netscape. He also wrote the SSL patent and promoted SSL as the Internet security standard within standard committees and the industry. Dr. Elgamal invented several industry and government standards in data security and digital signatures area, including the DSS government standard for digital signatures. In addition to serving on numerous corporate advisory boards, Dr. Elgamal is the Chief Security Officer at Axway, a global provider of multi-enterprise solutions and infrastructure. He holds a Ph.D. and M.S. in Computer Science from Stanford University. View more of his blog posts here.
