Abstract
An integrated circuit (IC), including a functional circuit and a security system, is disclosed. The functional circuit generates a request packet for an indirect memory access of a memory. The security system validates the functional circuit based on a security attribute and a functional identifier of the functional circuit. Based on the request packet and the validation of the functional circuit, the security system identifies an instruction sequence associated with the indirect memory access. Further, the security system determines a type of the indirect memory access based on the instruction sequence, and validates the type of the indirect memory access based on the security attribute and the request packet. Based on the validation of the type of the indirect memory access, the instruction sequence is executed, thereby facilitating the indirect memory access for the functional circuit.
