"Virtual Hierarchies: An Architecture for Building and Maintaining Efficient and Resilient Trust Chains."
Proceedings of the 7th Nordic Workshop on Secure IT Systems---NORDSEC 2002.

However, systems research has given us secure coprocessing for securely carrying out computations among multiple trust domains. Cryptography has produced a number of methods for distributing cryptographic computations, such as secret splitting and threshold cryptography. Last, distributed computing has given us peer-to-peer networking, for creating self-organizing distributed systems.
In this paper, we use these latter tools to address the former problem by overlaying a virtual hierarchy on a mesh architecture of peer certificate issuing entities, and achieving both resilience and efficiency.
