A first electronic processor determines that a first certificate in a first level of the trust chain is to be updated, updating the first certificate and each certificate in a lower level in the trust chain that is lower than the first level, creates a second version of the trust chain including an updated first certificate and an updated certificate at each lower level in the trust chain, and transmits the second version of the trust chain to one or more entities.
