The IBM Cryptographic Security Chip for PC Clients Manufactured by Atmel (AT90SP0801) resides on a daughter card on the system motherboard of an IBM Personal Computer (PC) or is surface mounted in an IBM ThinkPad. The IBM Cryptographic Security Chip performs RSA digital signature, RSA data decryption, and authentication. It is packaged in a 20 pin SOIC package or a 28 pin TSSOP package and includes EEPROM memory that can be loaded with RSA public/private key pairs. Communication with the main processor is via an SM bus. There are eleven simple commands accepted by the chip. The IBM Cryptographic Security Chip is used in a number of standard, off-the-shelf IBM PC Client configurations. The chip and its firmware and configuration are independent of the characteristics of the host PC.
The IBM Cryptographic Security Chip performs RSA signature and decryption. There are two types of key
