[5] Web Services Trust Language (WS-Trust) [6] brings trust management into the environment of web services. The core ...
Further, this definition of trust is abstract, allowing different instances and observers in a trusted system to communicate based on a common idea of trust (otherwise communication would be isolated in domains), where all necessarily different subjective and intersubjective realizations of trust in each subsystem (man and machines) may coexist.
The Trusted Computing Group is a group formed in 2003 as the successor to the Trusted Computing Platform Alliance which was previously formed in 1999 to implement Trusted Computing concepts across personal computers. [2] Members include Intel, AMD, IBM, Microsoft, and Cisco.
Code integrity: "Unauthorized entities cannot add, remove, or alter code executing in the TEE". In addition to trusted execution environments, remote cryptographic attestation is an essential part of confidential computing. The attestation process assesses the trustworthiness of a system and helps ensure that confidential data is released to a ...
