Atmel AT97SC3205P可信赖平台模块开发方案

Atmel公司的AT97SC3205P是可集成于个人电脑和其它嵌入系统的全集成可信赖平台安全模块,满足可信赖平台模块(TPM)的可信赖计算工作组(TCG)V1.2.模块采用动态内部存储器管理方案来存储多RSA密钥.TPM包括硬件随机码发生器(RNG),是OEM和ODM的完整解决方案.本文介绍了AT97SC3205主要特性,框图和可信赖平台模块(SPI接口)开发板AT97SC3205P-SDK2主要特性和电路图.
The Atmel AT97SC3205 is a fully integrated security module designed to beintegrated into personal computers and other embedded systems. It implementsversion 1.2 of the Trusted Computing Group (TCG) specification for TrustedPlatform Modules (TPM).
The TPM includes hardware Random Number Generator (RNG), including a FIPS certified Pseudo RandomNumber Generator that is used for key generation and TCG protocol functions. The RNG is also available to thesystem to generate random numbers that may be needed during normal operation.
The chip uses a dynamic internal memory management scheme to store multiple RSA keys. Other than thestandard TCG commands (TPM_FlushSpecific,TPM_Loadkey2), no system intervention is required to managethis internal key cache.
The TPM is offered to OEM and ODM manufacturers as a turnkey solution, including the firmware integrated on thechip. In addition, Atmel provides the necessary device driver software for integration into certain operatingsystems, along with BIOS drivers. Atmel will also provide manufacturing support software for use by OEMs andODMs during initialization and verification of the TPM during board assembly.
