Abstract
Technologies for software attack detection include a computing device with a processor and a memory external to the processor. The processor originates a memory transaction with an associated secure enclave status bit that indicates whether the memory transaction originated in a secure execution mode, such as from a secure enclave. The processor computes an error-correcting code (ECC) based as a function of memory transaction data and the secure enclave status bit, and performs the memory transaction based on the ECC and the memory transaction data using the memory of the computing device. The processor may store the ECC and the memory transaction data to memory. The processor may load a stored ECC and data from the memory and compare the computed ECC to the stored ECC to detect memory transactions with an invalid secure enclave status bit. Other embodiments are described and claimed.
