Sealed Identity | |
The Trusted Platform Module (TPM) is a special security chip, integrated on the mainboard of a system. This module functions like a permanently installed SmartCard. However, the TPM is not linked to a user like a SmartCard, but instead to a hardware system. The TPM contains a unique code. As a result, the TPM is used for the clear identification and authentication of the device. The two basic keys are saved in the TPM, the others on the repository. The TPM is also used for encryption and decryption of user-specific cryptography keys saved on data carriers.
For example, with the TPM activated, data can be generated which can only be read or run on this device. The support of security protocols, such as SSL (Secure Socket Layer) for Internet connections, IPSec (LAN encryption), S-MIME (e-mail encryption, WLAN encryption and others) is also possible.
To use the TPM, you must be sure to activate the TPM in the BIOS Setup before the software installation. Activate the TPM by selecting the entry “Enabled” for Embedded Security Chip in the security menu.
TPMs and SmartCards perform both similar and different functions. A SmartCard provides authentication and protection of information for individual users. On the other hand TPM provides authentication key-based access protection on individual platforms. While there are some overlaps between the uses of these two technologies they are, in fact, complementary.
The following Fujitsu Siemens Computers applications utilize the TPM:
SmartCase Logon+ suite
SmartCase OS Logon (Smarty)
SmartCase SSO Password Manager
SmartCase Secure Drive
