Public-Key Infrastructures (PKI) are considered as the safeguard of the security of communications on large scales networks like Internet. Different trust models have been proposed to interconnect the various PKIs components in order to propagate the trust between them. This paper provides a simple model for trust and reputation management in PKI architectures, and a new algorithm to assess trust relationships in a network using different trust evaluation schemes.
