Credible certification technology is the core of modern information security. As an important issue, after several decades of academic discussions and practice, there are gradually formed two major technology systems. One is PKI (Public Key Infrastructure), the other is IBE (Identity Based Encryption). Credible certification technology is the basis confidence-building of e-commerce, e-government and other
