SELF-DESCRIBED SECURITY MODEL FOR RESOURCE ACCESS

Various embodiments provide techniques and devices for implementing a self-described security model for sharing secure resources between secure applications. In some examples, a trustlet can include a self-described policy defining capabilities of the trustlet and/or membership in a scenario group managed by a signing authority. Further, the trustlet can include a code signature signed by the signing authority. Additionally, a proxy kernel can allow the trustlet to share application data with other trustlets in the scenario group based on the policy and the code signature without exposing the application data to compromised system software and/or unauthorized applications.
