Abstract
A secure update is provided from a server to an end-point device. The server registers digital information, such as a name or a software package, and a verifiable key, such as a cryptographic hash, derived from the digital information. A publicly accessible transaction log stores the verifiable key in a block and provides an identifier of the block to the server. An end-point device receives the digital information and the identifier, and computes a separate verifiable key. The end-point device retrieves the verifiable key from the block of the publicly accessible transaction log, and compares the retrieved verifiable key to the separate verifiable key to determine whether the digital information has been compromised.
