HP ProtectTools Troubleshooting Guide Acronym Term Detail EFS Encryption File System A transparent file encryption service provided by Microsoft for Windows 2000 or later LPC Low Pin Count Defines an interface used by the HP ProtectTools Embedded Security device to connect with the platform chipset. The bus consists of 4 bits of Address/Data pins, along with a 33Mhz clock and several control/status pins. MSCAPI: Microsoft Cryptographic API, or CryptoAPI An API from Microsoft that provides an interface to the Windows operating system for cryptographic applications PKCS Public Key Cryptographic Standards generated that govern definition and use of Public Standards Key/Private Key means of encryption and decryption. PKI Public Key Infrastructure A general term defining the implementation of security systems that use Public Key/Private Key encryption and decryption PSD Personal Secure Drive A feature that is provided by HP ProtectTools Embedded Security. This application creates a virtual drive on the user's machine that automatically encrypts files/folders that are moved into the virtual drive. S/MIME Secure Multipurpose Internet Mail Extensions A specification for secure electronic messaging using PKCS. S/MIME offers authentication via digital signatures and privacy via encryption TCG Trusted Computing Group Industry association set up to promote the concept of a "Trusted PC." TCG supersedes TCPA TCPA Trusted Computing Platform Trusted computing alliance; now superseded by TCG Alliance TPM Trusted Platform Module TPM hardware and software enhances the security of EFS and the Personal Secure Drive by protecting the keys used by EFS and the Personal Secure Drive. In systems without the TPM, the keys used for EFS and the PSD are normally stored on the hard drive. This makes the keys potentially vulnerable. In systems with the TPM card, the TPM's private Storage Root Keys, which never leave the TPM chip, are used to "wrap" or protect the keys used by EFS and by the PSD. Breaking into the TPM to extract the private keys is much more difficult than hacking onto the system's hard drive to obtain the keys. The TPM also enhances the security of secure e-mail via S/MIME in Microsoft Outlook and Outlook Express. The TPM functions as a Cryptographic Service Provider (CSP). Keys and certificates are generated and/or supported by the TPM hardware, providing significantly greater security than software-only implementations. Technical Reference Guide www.hp.com 3
