iperfTZ: Understanding Network Bottlenecks for TrustZone-based Trusted Applications [article]

Christian Göttel, Pascal Felber, Valerio Schiavoni
2019 arXiv   pre-print
open-source tool to uncover network performance bottlenecks rooted at the design and implementation of trusted applications for ARM TrustZone and underlying runtime systems.  ...  Our evaluation based on micro-benchmarks shows current trade-offs for trusted applications, both from a network as well as an energy perspective; an often overlooked yet relevant aspect for edge-based  ...  Our tool can be used to guide the calibration of TAs for demanding workloads, for instance understanding the exchanges with untrusted applications or for secure inter-TEE applications [26] .  ...
