Ultra-low latency AES-GCM Crypto Engine for PCI Express 5.0 and CXL 2.0 | Security | Silex Insight

May 11, 2021

Silex Insight extends their AES-GCM Crypto Engine offering by introducing an ultra-low latency version for PCI Express 5.0 and Compute Express Link 2.0

Silex Insight, a leading provider for flexible security IP cores, announces today a complete family (3 variants) of their NIST-compliant AES-GCM crypto engines by adding an ultra-low latency version to their portfolio to serve high-performance computing (HPC) SoCs using the PCI Express® (PCIe®) 5.0 architecture or Compute Express Link (CXL) 2.0 interface.


The AES-GCM ultra-low latency crypto engine is targeted for CXL link encryption with an implementation of the AES-GCM algorithm compliant with the NIST SP 800-38D standard. The unique architecture enables high throughput while maintaining an optimal resource usage.

The AES-GCM is the only authenticated encryption algorithm recommended by NIST supporting 64 GB/s. In addition, it also offers zero latency on the encryption/decryption path.

One of many new great features that comes with CXL 2.0 is the support for single level switching to enable fan-out to multiple devices. This will enable many devices in a platform to migrate to CXL, while maintaining the backward compatibility and the low-latency characteristics of CXL. 

All 3 AES-GCM crypto engine variants from Silex Insight accommodate the different market needs;

The AES-GCM Ultra-low latency crypto engine from Silex Insight has proven to be effective as some selected customers have already done the implementation into their designs. As of today, it is now available to everyone who needs to serve high-performance computing (HPC) SoCs using the PCIe 5.0 architecture or CXL 2.0 interface.
