Abstract
Apparatuses, systems, and methods for providing security in an intelligent electronic device (IED) are provided. In one aspect of the present disclosure, an IED is provided including at least one processor that receives a communication via a communication interface, the communication including an unencrypted file and a digital signature. The at least one processor decrypts the digital signature to obtain a first value, executes a hash function on the unencrypted file to obtain a second value, determines if the first value and second value match, and updates at least one firmware package stored in at least one memory of the IED with the unencrypted file if it is determined that the first value and the second value match.
