Tracking of resource utilization during cryptographic transformations

摘要

A computer system that communicates cryptographic resource utilization information while processing data packets is described. During operation, the system receives a first data packet and generates a second data packet by performing a cryptographic transformation on the first data packet. Next, the system appends auxiliary information to the second data packet. This auxiliary information includes information associated with cryptographic resource utilization during the cryptographic transformation. Then, the system provides the second data packet including the auxiliary information.
