Abstract:

This work presents ASAP, a 28-nm transformer-training accelerator that combines N:M structured sparsity with asymmetric microscaling floating-point (MXFP) precision through a unified algorithm–hardware co-design. ASAP introduces a progressive sparsity schedule in which pruned compute resources are reassigned to increase numerical precision for important weights and activations, stabilizing optimization …

Abstract:

White-box cryptography (WBC) seeks to protect secret keys (SKs) even under the white-box security model that features adversaries having full control of the execution environment. Due to the ever-growing demand for content protection under security-critical scenarios, the recent progress on WBC has been nothing short of spectacular. However, the security-prioritized …
