Visible to the public ArmoredSoftware: Trust in the cloud


ArmoredSoftware is a new approach for establishing and maintaining trust among software systems operating in a cloud computing environment. Using remote attestation techniques, ArmoredSoftware components assess their environments and determine appropriate actions ranging from simply reporting issues to migration and mitigation. Each ArmoredSoftware component is packaged with lightweight measurement, attestation and appraisal capabilities that use TPM virtualization techniques to establish and maintain roots of trust. Appraisal capabilities request information from other collocated software components and the operational environment that respond by executing attestation protocols to gather and report evidence. Using techniques from trusted computing, attestation protocols also generate cryptographic signatures used to assess the trustworthiness of gathered evidence. In the appraiser, gathered evidence is used to assess the appraisal target while cryptographic signatures are used to assess trustwortniness of evidence.

This poster and accompanying demonstration represent the first public presentation of the ArmoredSoftware approach. We will outline the ArmoredSoftware architecture describing appraisal, attestation, and measurement. We will briefly present our evolving approach focusing on measurement and execution of attestation protocols. Our demonstration will show and end-to-end demonstration of a simple appraisal activity illustrating important ArmoredSoftware concepts.
