QUAC 100 Release Notes
New Features #
QUAC 100 firmware v1.2.0 introduces significant performance improvements and expanded algorithm support over the previous v1.1.x release series:
ML-KEM Performance Optimization
The Radix-32 NTT engine has been further optimized to deliver 1.4 million ML-KEM-768 encapsulation operations per second, representing a 12% improvement over v1.1.3. Latency for single operations has been reduced to sub-700 nanosecond end-to-end for the complete encapsulation cycle.
ML-DSA Batch Signing
New batch signing mode enables up to 850,000 ML-DSA-65 signature operations per second when processing queued requests. The job dispatcher now supports priority-weighted fair queuing across multiple cryptographic contexts.
QRNG Throughput Enhancement
Quantum random number generation conditioned output has been increased to >800 Mbps (up from 400 Mbps in v1.1.3) through improvements to the dual free-running ring oscillator entropy collection pipeline. Raw pre-conditioning bitrate is approximately 1.5 Gbps. Real-time NIST SP 800-90B compliance monitoring is now integrated into the conditioning path.
Resolved Issues #
The following issues have been resolved in firmware v1.2.0:
| Issue ID | Component | Description |
|---|---|---|
| QUAC-1847 | NTT Engine | Fixed occasional coefficient overflow during ML-KEM-1024 decapsulation under sustained high-throughput load |
| QUAC-1823 | PCIe Interface | Resolved DMA completion timeout on certain AMD EPYC 9004 series platforms with IOMMU enabled |
| QUAC-1801 | HSM Module | Corrected key slot deallocation race condition during concurrent multi-tenant key lifecycle operations |
| QUAC-1789 | QRNG | Fixed entropy pool starvation during sustained high-throughput consumption with multiple simultaneous consumers |
| QUAC-1776 | Power Mgmt | Resolved incorrect C-state transition causing 200μs wake latency spike in dynamic power scaling mode |
