Abstract

Systems for authenticating a file are disclosed. A system may include one or more physical devices. The one or more physical devices may select, based on an identifier, a subset of data segments of a computer file for generating a first digest with a cryptographic function. The one or more physical devices may also execute the cryptographic function on the selected subset of data segments of the computer file to generate the first digest. Further, the one or more physical devices may generate an authenticator based on the first digest and a private key. The one or more physical devices may further send the computer file, the identifier, and the authenticator to a secure node. Associated methods and non-transitory machine-readable medium are also disclosed.
