Abstract
According to one embodiment, a host communicates with a data processing (DP) accelerator using an obfuscation scheme. The DP accelerator receives an obfuscation kernel algorithm (or obfuscation algorithm), where the obfuscation kernel algorithm is used to obfuscate and de-obfuscate data in communication with a host. The DP accelerator de-obfuscates, using the obfuscation kernel algorithm, obfuscated data received from the host for a prediction request to obtain one or more AI models. The DP accelerator generates prediction results by applying the one or more AI models to a prediction input. The DP accelerator obfuscates, using the obfuscation kernel algorithm, the prediction results. The DP accelerator sends the obfuscated prediction results to the host, where the host retrieves the prediction results by de-obfuscating the obfuscated prediction results.
