Abstract:
1. A system comprising: an access module configured to access authentication information made available by a first computing device, the authentication information including content data, a public key of the first computing device, a first network address of the first computing device, and a digital signature; a deriving module configured to derive a portion of a second network address from the public key of the first computing device by taking a portion of a value derived by hashing a combination of the public key and a modifier; a validation module configured to validate the digital signature using the public key; an accepting module configured to accept the content data when the derived portion of the second network address matches a corresponding portion of the first network address and when the digital signature is valid; and one or more processing units configured to execute the access module, the deriving module, the validation module, and the accepting module.
