摘要：
In one embodiment, an encryption operation may be performed by obtaining a product of a carry-less multiplication using multiple single instruction multiple data (SIMD) multiplication instructions each to execute on part of first and second operands responsive to an immediate datum associated with the corresponding instruction, and reducing the product modulo g to form a message authentication code of a block cipher mode. Other embodiments are described and claimed.
