AI Technical Summary
In existing technologies, NTT modules are easily targeted by fault injection attacks in lattice cryptography hardware implementations. Traditional detection schemes have excessive hardware overhead and are difficult to deploy in resource-constrained application scenarios, leading to security and efficiency issues.
The pre-calculation module performs offline calculations to determine pre-calculation constants, the NTT operation module performs transformations, the check value calculation module calculates the check object through hardware shifting, addition, and subtraction, and the fault judgment module performs consistency verification, thereby achieving lightweight fault detection and reducing hardware computational complexity and overhead.
It achieves efficient NTT fault detection, reduces hardware power consumption and latency, adapts to low power consumption requirements, is suitable for resource-constrained environments, ensures security and stability, and is compatible with existing hardware accelerators without major modifications.
