Abstract
A processing device comprises a processor coupled to a memory and is configured to associate intermediate values of a hash chain with respective access control intervals, and to provide a given one of the intermediate values to user in order to allow the user to access a protected resource in the corresponding access control interval. A final value of the hash chain is provided to an access control module associated with the protected resource, and an initial value of the hash chain is stored in a secure manner. The hash chain may be generated by applying a one-way hash function to the initial value a designated number of times in order to obtain the intermediate values and the final value. The protected resource may comprise, for example, a storage array or other processing platform component, with the intermediate values controlling service technician access to that component.
