Abstract

Methods, systems, apparatuses, and computer program products are provided for protecting data in a memory of an integrated circuit (IC). A process token is obtained in a special purpose IC from a host that is external to and communicatively connected to the special purpose IC. The process token is stored in a first memory portion of the special purpose IC. In response to receiving a processing request from the host, the processing request is processed, and data generated by processing the processing request is written in a second memory portion of the special purpose IC. When a read request is received to read the data in the second memory portion, a determination is made whether the read request includes a read token that matches the previously stored process token. If the read token matches the process token, the data in the second memory portion may be returned to the host.
