method for managing dynamic and secure authenticated in a relational database table

摘要

Method for the dynamic secure management of an authenticated relational table forming part of a database; the method comprises the following steps: store the authenticated relational table in a secondary memory' with a high storage capacity and a slow data access time; maintain an authenticated skip list within the authenticated relational table in order to create an authentication superstructure; determine a signed hash or basis value which characterizes the entire authenticated relational table; authenticate the presence or otherwise of a set of elements belonging to the skip list via a root path suitable for calculating a check hash value comparable to the signed hash value which characterizes the entire authenticated relational table; and validate the result of the authentication step by checking that the check hash value calculated by means of the root path is equal to the signed hash value that characterizes the entire authenticated relational table.
