Abstract
Embodiments may include generating an initial verifier for a first process, the initial verifier generated based on a trusted image of the first process. Embodiments may include, subsequent to generating an untransformed secret associated with the first process, using a reversible transform to transform the untransformed secret with the initial verifier to generate a transformed secret associated with the first process. Embodiments may also include, subsequent to the first process being launched outside of a secure domain, and dependent upon a second verifier generated from a current state of the first process being the same as the initial verifier: using the reversible transform to reverse transform the transformed secret with the second verifier to generate a de-transformed secret equal to the untransformed secret. Embodiments may include performing a secure communication protected with a cryptographic key generated based on the de-transformed secret. The communication may be performed across different security domains.
