What does WebBiss do?

WebBiss is a browser-based WebGPU tool for benchmarking local DVB-CSA1 / BISS key-search workloads, comparing kernels, importing MPEG-TS samples, and measuring throughput in controlled environments.

Does WebBiss send TS data to a server?

The tool is designed for local browser execution so researchers can test sample windows, dispatch sizing, and throughput without uploading capture data to a remote service.

Who should use WebBiss?

WebBiss is intended for defensive security research, GPU benchmarking, academic discussion of legacy cipher margins, and authorized testing on content or systems the operator is permitted to analyze.
