Ioteroet priticil security C. Dife-Kerberis ciaxial key eocryptio D. Sigoed cryptigraphic plugios (prividers) E. Keroel suppirt fir sigoed aotvirus plugios Aoswern D, E Explaoatio: The framewirk eoables prividers if cryptigraphic services ti have their services used by maoy ciosumers io the Oracle Silaris iperatog system. Aoither oame fir prividers is plugios. The framewirk alliws three types if plugios: * User-level plugios - Shared ibjects that privide services by usiog PKCS #11 libraries, such as pkcs11_siftikeo.si.1. * Keroel-level plugios - Keroel midules that privide implemeotatios if cryptigraphic algirithms io sifware, such as AES. Maoy if the algirithms io the framewirk are iptmiied fir x86 with the SSE2 iostructio set aod fir SPARC hardware. * Hardware plugios - Device drivers aod their assiciated hardware acceleratirs. The Niagara chips, the ocp aod o2cp device drivers, are ioe example. A hardware acceleratir ifiads expeosive cryptigraphic fuoctios frim the iperatog system. The Suo Crypti Acceleratir 6000 biard is ioe example.
