Encoding Core Description | Features | Applications | Block Diagram | Implementation | Export Permits | Deliverables The AES_E core implements Rijndael encoding in compliance with the NIST Advanced Encryption Standard. It processes 128-bit blocks, and is programmable for128-, 192-, and 256-bit key lengths. Features Encrypts using the AES Rijndael Block Cipher Algorithm Satisfies Federal Information Processing Standard (FIPS) Publication 197 from the US National Institute of Standards and Technology (NIST) Processes 128-bit data in 32-bit blocks Employs user-programmable key size of 128, 192 or 256 bits Smallest version supports a single block cipher mode, Electronic Codebook (ECB); these modes can be added as needed: Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB) and Counter (CTR) Works with a pre-expended key or can integrate the optional key expansion function Simple, fully synchronous, reusable design Available as fully functional and synthesizable VHDL or Verilog, or as a netlist for popular programmable devices Complete deliverables include test benches Applications Protected network routers Electronic financial transactions Secure wireless communications Secure video surveillance systems Encrypted data storage Block DiagramImplementation Results Device Utilization and Performance
