VERSATILE AES-256 IP CORE

Advanced Encryption Standard (256-bit key), ECB, CBC, OFB, CFB, and CTR Mode of Operation

Product code: XIP1123B

This IP Core from Xiphera is a balanced and versatile Intellectual Property (IP) core implementing the Advanced Encryption Standard (AES) with a 256-bit key in five dynamically selectable modes of operation: Electronic Codebook (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB) , and Counter (CTR). The four different modes of operation (CBC, CFB, OFB, and CTR) all protect data confidentiality, and are widely used in numerous security designs and cryptographic protocols.

This document details FPGA and ASIC resource requirements and performance for the default configuration, including instantiation parameters, supported features, and the selected bus interface.
