PC21100  Product Folder

The PC21100 is a single-chip Trusted Platform Module (TPM) solution for PC security based on the TCPA standard. It is fully TCPA-compliant and offers system designers all the advantages of Trusted Computing as defined by the TCPA.

The PC21100 is a member of the National Semiconductor® TrustedI/O family, which provides TCPA-compliant security functions. The PC21100 includes a CompactRISC embedded RISC core for hidden execution of security code, flash memory-based secured information storage, SecureRun, a performance accelerator that supports cryptographic algorithms (SHA-1 and RSA), and a true RNG. In addition, the PC21100 integrates a variety of system functions, enabling efficient implementation of a highly secure trustworthy system.

The PC21100 provides desktop and mobile PC platforms with:

System integrity checks:
Ensures that no unauthorized changes have been made to the hardware or software

Authentication:
Provides assurances that the source of the data is valid and as expected

Data integrity checks:
Provides assurances that received data is exactly as sent

Secure storage:
Protects sensitive and confidential data, such as credit card numbers and passwords

Trustworthiness:
Allows the user to trust authorized third parties, while proving that the user's PC is trustworthy and maintaining privacy
