Abstract

Techniques are disclosed for a post-quantum encrypted trusted execution environment on an edge device. The edge computing device includes a trusted execution environment that includes at least some SIMD processing units, such as a graphics processing unit (GPU). Data records, such as machine learning inferences from machine learning or artificial intelligence models, are generated on the edge computing device in the trusted execution environment and encrypted with post-quantum encryption (such as lattice-based encryption) using the SIMD processing units in the trusted execution environment. Workloads received for the trusted execution environment, also encrypted with post-quantum encryption, are decrypted using the SIMD processing units in the trusted execution environment.
