متن کاملReputation Systems for Trust Management in the Web PKI
This thesis’ goal is to reduce the attack surface of the existing Web Public Key Infrastructure (PKI) by applying user trust as in real world scenarios of human trust establishment. Reputation systems can be used to exchange Certification Authority (CA) trust information and lower the risk on relying on malicious CAs. The matter in question is connection trust, determining whether a SSL/TLS con...
متن کاملTrust Views for the Web PKI
The steadily growing number of certification authorities (CAs) assigned to the Web Public Key Infrastructure (Web PKI) and trusted by current browsers imposes severe security issues. Apart from being impossible for relying entities to assess whom they actually trust, the current binary trust model implemented with the Web PKI makes each CA a single point of failure. In this paper, we present th...
متن کاملReducing the Dependence of Trust-Management Systems on PKI
Trust-management systems address the authorization problem in distributed systems by defining a formal language for expressing authorization and access-control policies, and relying on an algorithm to determine when a specific request can be granted. For authorization in distributed systems, trustmanagement systems offer several advantages over other approaches, such as support for delegation a...
متن کاملPKI Trust Models
A PKI can be described as a set of technologies, procedures and policies for propagating trust from where it initially exists to where it is needed for authentication in online environments. How the trust propagation takes place under a specific PKI depends on the PKI’s syntactic trust structure which is commonly known as a trust model. However, trust is primarily a semantic concept that can no...
