Abstract

A life cycle certificate implementing a Merkle tree-based data structure enables validating a current life cycle stage and securely transitioning a life cycle stage of a first component or product to a next life cycle stage in a forward-only direction. The life cycle certificate comprises a life cycle index, a first-level hash value or a reference thereto, at least one second-level hash value or a reference thereto, a third-level hash value and a further third-level hash value or a corresponding reference thereto. The third-level hash values represent hashes of corresponding sensitive data associated with a respective value of the life cycle index. The life cycle certificate further comprises a control hash value, which is a hash value of the concatenation of all other constituents of the data structure. A method of forward-only transitioning a life cycle stage of a product uses the life cycle certificate and the unique properties of Merkle tree-based data structures for preventing transitions to an earlier life cycle stage.
