xFaceAES
xFaceAES is a high-speed encryption unit for application in FPGAs. The soft core encrypts datastreams up to 2 Gbps. It requires only little hardware resources on Xilinx FPGAs.
Application
Application of xFaceAES as encryption unit
The Advanced Encryption Standard (AES) is used in many security applications. xFaceAES offers incredible performance at smallest footprint. Application of high-throughput AES are:
- IPsec encryption (AES-CBC)
- Pseudo-random function (AES-XCBC-PRF)
Deliverables
- Source code
- Synthesizable Verilog code
- Mostly behavioral code
- Simulation
- Testbench and test data
- Documentation
- Including getting started tutorial
- Optional
- Customization and integration services
