High-Speed AES Encryption Cores (RJDCEO/RJDCDO/RJDCED)
Features
- >2.5 Gbits per second (Gbps) throughput for fiber-speed encryption
- Key-agility on both encryption and decryption allows keys to be switched without stalling the core
- Simple streaming architecture obviates the need for elaborate control logic outside the core
- Bypass control allows data flow-through for selective encryption
- Simple 32-bit data and key ports reduce logic required to interface to high-speed standards

Overview
D'Crypt's AES core is a high-performance pipelined implementation of the AES (Rijndael) encryption algorithm. Optimized for programmable logic device (PLD) architectures, the function achieves in excess of 2.5-Gbps encryption and decryption throughput on 128-bit block sizes when implemented on an Altera® APEX™ 20KE or equivalent device. It employs a 128-bit key and features zero key-setup latency on both encryption and decryption. With key-agility and selective bypass control, D'Crypt's AES core is the ideal building block for high-performance packet-smart routers and switches.
