Abstract
In a dispersed storage network access control list information must be occasionally written out to system units across the network. A dispersed storage (DS) managing unit (18) combines (204) the access control list information with a clock stamp and hashes (206) that combined output. An encryptor (208) encrypts a security key (210) and the hash output to obtain a signature. A combiner (212) combines the signature and the output of combiner (204) and outputs to a publisher (214). Upon receipt of the output of the publisher (214) a dispersed storage unit (44) can reverse process and securely validate the access control list information provided by the publisher (214) to receive and store updated and valid access control list information. This processing is performed by the unit (44) using parsers (216), caches (218 and 228), hash operations (224), decryptors (222), comparators (226), logic (230), and key stores (220).
