Abstract
An example system includes a processor to partition an arithmetic circuit representing a homomorphically encrypted (HE) code into a number of execution blocks. The processor can generate, for each of the number of execution blocks, manifests describing access patterns for a number of different machine environments. The processor can then dynamically execute the HE code by selecting successive blocks to execute based on an access pattern calculated for the execution block corresponding to a detected current machine environment.
