The core technology of PC security is concentrated in TPM chip.

： RSA is an important public key algorithm and is widely used in data encryption and digital signature．Using PC Security Card to implement data encryption is more secure and faster than using software．In this paper，we discuss the design of PC Security Card based on TMS320C54x chipset．By analyzing its instruction set，we project a method to improve the speed of RSA on this chip
