Abstract
A system that generates an electromagnetic interference (EMI) fingerprint for a computer system is presented. During operation, the system executes a load script on the computer system, wherein the load script includes a specified sequence of operations. Next, the system receives EMI signals generated by the computer system while executing the load script. The system then generates the EMI fingerprint from the received EMI signals.
Claims25
A method for generating an electromagnetic interference (EMI) fingerprint for a computer system, comprising:
- executing a load script on the computer system, wherein the load script includes a specified sequence of operations, wherein the specified sequence of operations produces a customized load profile that generates a unique EMI fingerprint;
- receiving EMI signals generated by the computer system while executing the load script;
- and
- generating the EMI fingerprint from the received EMI signals.
A computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for generating an electromagnetic interference (EMI) fingerprint for a computer system, wherein the method comprises:
- executing a load script on the computer system, wherein the load script includes a specified sequence of operations, wherein the specified sequence of operations produces a customized load profile that generates a unique EMI fingerprint;
- receiving EMI signals generated by the computer system while executing the load script;
- and
- generating the EMI fingerprint from the received EMI signals.
An apparatus that generates an electromagnetic interference (EMI) fingerprint for a computer system, comprising:
- an execution mechanism configured to execute a load script on the computer system, wherein the load script includes a specified sequence of operations, wherein the specified sequence of operations produces a customized load profile that generates a unique EMI fingerprint;
- a receiving mechanism configured to receive EMI signals generated by the computer system while executing the load script;
- and
- a fingerprint-generation mechanism configured to generate the EMI fingerprint from the received EMI signals.
