The OFB AES Encryption/Decryption IP Core provides a balance between high throughput and size for the Output Feedback (OFB) mode of operation. The IP core comes with either a 32-bit or 128-bit IO interface and integrated key expansion supporting 128, 192, and 256-bit keys. The core is designed for applications that need high throughput, low latency, and reduced power consumption.
For additional security the core integrates a quick key wipe feature allowing the key to be erased both fast and securely.
