Intel Virtualization Technology for Directed I/O (VT-d) Intel Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) & Itanium processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security & reliability of the systems & also improve performance of I/O devices in virtualized environments. Intel Virtualization Technology (VT-x) Intel Virtualization Technology (VT-x) allows one hardware platform to function as multiple “virtual” platforms. It offers enhanced manageability by limiting downtime & maintaining productivity by isolating computing activities into separate partitions. Intel Platform Trust Technology (Intel PTT) Intel Platform Trust Technology (Intel PTT) is a platform functionality for credential storage & key management used by Windows 8* & Windows 10. Intel PTT supports Bit Locker* for hard drive encryption & supports all Microsoft requirements for firmware Trusted Platform Module (f TPM) 2.0. Intel AES New Instructions Intel AES New Instructions (Intel AES-NI) are a set of instructions that enable fast & secure data encryption & decryption. AES-NI are valuable for a wide range of cryptographic applications, for example: applications that perform bulk encryption/decryption, authentication, random number generation, & authenticated encryption.
