Abstract
A computer-implemented method for trust propagation of signed files across devices may include identifying a signed file on a device, calculating, on the device, a hash based at least in part on the signed file, querying, with the hash, a server which has verified that the signed file is trustworthy based on a digital signature of the signed file having been verified by an additional device capable of verifying digital signatures, receiving on the device, in response to querying the server, a trust indicator indicating that the digital signature of the signed file has been verified and trusting the signed file on the device, based on the trust indicator indicating that the digital signature of the signed file has been verified. Various other methods, systems, and computer-readable media are also disclosed.
