US 8,266,691 B2 · Renewable integrity rooted system

Abstract

A method of validating software is disclosed. The method may include receiving, at a first function, a first hash and a first version. The first function may validate a second function according to the first hash and first version. The second function may receive a second hash and a second version, and the second function may validate a third function according to the second hash and second version. The first version and first hash may be stored within the first function, for example. The first version and first hash may be stored within a manifest, for example. In another embodiment, a method of validating software may include storing a plurality of functions and storing a version and hash for each function. Each function may be verified according to the respective version and hash, and each function may verify at least one other function.

Dependent claims

A non-volatile computer-readable storage medium for validating software, wherein the storage medium is not a signal, the computer-readable storage medium including computer executable instructions to perform acts comprising:

receiving, at a first function, a first hash, a first size and a first version;
validating, by the first function, a second function according to the first hash, the first size and the first version at least in part by using the first function to hash the second function according to a hash function and comparing a first output of the hash function to the first hash;
receiving, at the second function, a second hash and a second version;
and
validating, by the second function, a third function that is different than the first function according to the second hash and second version at least in part by using the second function to hash the third function according to the hash function and comparing a second output of the hash function to the second hash.
