Revision 1.0
PC21100 (SafeKeeper
TM
)
LPC-Based TCPA-Compliant Security Controller
General Description
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
