Selective generation of secure signatures in a distributed storage network

A method for execution by a processing module of one or more computing devices of a dispersed storage network (DSN), the method comprises:

• receiving, at the processing module, a first signature contribution request, wherein the first signature contribution request includes a payload;
• logging, by the processing module, the first signature contribution request, wherein the logging includes a timestamp for the first signature contribution request;
• determining, by the processing module, whether the timestamp of the first signature contribution request compares favorably to a timing template;
• when the timestamp of the first signature contribution request does not compare favorably to the timing template,
• outputting, by the processing module, a first signature contribution request rejection message;
• when the timestamp of the first signature contribution request compares favorably to the timing template, determining, by the processing module, whether the first signature contribution request compares favorably to a functionality template;
• when the first signature contribution request compares favorably to the functionality template, retrieving, by the processing module, a key share based on sharing function parameters and outputting a signature result;
• and
• when the first signature contribution request does not compare favorably to the functionality template, outputting, by the processing module, a second signature contribution request rejection message.
