Systems and methods for determining whether to evaluate the trustworthiness of digitally signed files based on signer reputation

摘要

A computer-implemented method for determining whether to evaluate the trustworthiness of digitally signed files based on signer reputation may include (1) identifying a file, (2) determining that the file has been digitally signed, (3) identifying a signer responsible for digitally signing the file, (4) identifying the signer's reputation, and then (5) determining whether to evaluate the trustworthiness of the file based at least in part on the signer's reputation. In one example, the signer's reputation may be based at least in part on the determined trustworthiness of at least one additional file that was previously signed by the signer. Various other methods, systems, and encoded computer-readable media are also disclosed.
