This has nothing to do with PKI, but it is an inherent characteristic of how we extend trust to others. A partial response to this problem is to encourage interoperability between providers of trust services. This should increase the number of trust-enabled services by allowing existing end users to profit from an extended trust model. Note, however, that this assumes that the end users will be sufficiently aware of the underlying issues to judge whether the basis for trust is appropriate or not.
At present, we have only partial answers to these questions. By deploying specially designed authentication protocols, based on a cryptographic approach, we can effectively solve the problem of authentication. However, the way in which we associate security credentials (the things end users possess in order to authenticate themselves) with end users involves creating and implementing trust models, and this area is still a subject of much discussion [14, 15]. Despite its tormented beginnings [16, 17], public key infrastructure (PKI) is still one of the most promising approaches in this area and has become the de facto standard for implementing trust on the Internet.
The simplest response is to simply accept it. This is appropriate TLFeBOOK 28 Management techniques when the cost of mitigation is greater than the expected loss, providing of course that there are no legal or regulatory restrictions requiring another course of action.
