CLP-200: Pipelined GCM-AES Core
The CLP-200: Pipelined GCM-AES core implements the GCM-AES algorithm as specified in NIST Special Publication 800-38D “Recommendation for Block Cipher Modes of Operation: Galois/Counter Mode (GCM) and GMAC”. For high performance cryptographic systems, AES-GCM is the algorithm of choice. It uses a high performance MAC algorithm based on Galois Field multiplication and CTR mode encryption which can be pipelined for high throughput operations.
The CLP-200 has several configuration options which allow the performance of the resulting core to be tailored to the system performance requirements. The key configuration options include:
- The number of AES cores instantiated which determines the core bandwidth
- The number of key expanders
- The number of key contexts
- Key size options – 128-, 192- and/or 256-bits
- Ingress/egress FIFO depths
- Features
- Scalable architecture configurable from 18 to 128 bits/cycle (5 – 40 Gbps)
- Flow through design
- Fully interleaved capabilities on any number of contexts
- Stall mitigation when context switching
- Supports 128-, 192- and 256-bit keys
- GCM and GMAC modes
- Scalable context switch rate
