D Richard Kuhn: Implementation of role-based access control in multi-level secure systems. The United States of America represented by the Secretary of Commerce, Michael De Angeli P C, February 8, 2000: US06023765 (234 worldwide citation)

Role-based access control (RBAC) is implemented on an multi-level secure (MLS) system by establishing a relationship between privileges within the RBAC system and pairs of levels and compartments within the MLS system. The advantages provided by RBAC, that is, reducing the overall number of connecti ...

David W Kravitz: Digital signature algorithm. The United States of America represented by the Secretary of Commerce, Schnader Harrison Segal & Lewis, July 27, 1993: US05231668 (170 worldwide citation)

A method is provided for generating and verifying a digital signature of a message m. This method requires a pair of corresponding public and secret keys (y and x) for each signer, as well as a pair of public and secret values (r and k) generated for each message by the signer. The public value r is ...
