Securing applications using trusted execution environments

Joshua David Lind, Peter Pietzuch
In this thesis, we explore how applications can overcome the security challenges posed by the use of TEEs. We provide the following contributions: 1. Minimising the trusted computing base (TCB).  ...  To minimise the TCB of applications and reduce the risk of vulnerabilities, we propose automatic application partitioning for TEEs: a principled approach for partitioning existing applications to be deployed  ...  In Bitcoin, global throughput is limited to 7 transactions per second [Nak08] , and the total size of the blockchain is 100s of GBs [DW15] .  ...
