Synopsis
Carry-less multiplication is the multiplication in the polynomial ring over GF(2). This is a critical operation in some cryptographic workloads, particularly the AES-GCM authenticated encryption scheme. This extension provides only the instructions needed to efficiently implement the GHASH operation, which is part of this workload.
