ABSTRACT:
A requested cryptographic function is validated for performance in conjunction with a cryptographic key, by inputting a first portion of an associated control vector into a first control vector checker, which outputs a first authorization signal if the requested cryptographic function has been authorized by the originator of the key. A second portion of the control vector is input to a second control vector checker, which outputs a second authorization signal if the requested cryptographic function has been authorized by the originator of the key. Both the first and the second authorization signals are applied to a cryptographic processor which initiates the execution of the requested cryptographic function.
