Multi-Purpose AES

Compact and high-speed AES Crypto Engine supporting a wide range of performance requirements and cipher modes like ECB, CBC, CFB, OMAC and XTS and interleaved CTR, CCM, XTS and GCM on ASIC and FPGA



The BA411E-FLEX core is a multi-purpose, flexible and reconfigurable AES Crypto engine. The granular and scalable implementation of the AES algorithm makes the solution suitable for a wide and full range of requirements (from low-cost to ultra-high-speed). The engine is easily reconfigurable through a generic function.

The silicon-proven core is optimized and suited for any target technology (ASIC, Altera, Microsemi, Xilinx)

With a very flexible wrapper supporting a wide selection of programmable ciphering modes (ECB, CTR, CBC, CFB, OFB, OMAC, CCM/CMAC, GCM/GMAC and XTS) and several options of data interfaces (FIFO, DMA, AXI4-Stream, …), the BA411E-FLEX is an easy-to-use solution with predictable resources and performances on ASIC and FPGA.
