  • Computer architecture for a handheld electronic device with a shared human-machine interface
    Patent number: 7779252
    Abstract: Mobile PDA computer system (300) includes a secure user processor (302), a non-secure user processor (306), a cryptographic engine (304), and a shared human/machine interface (HMI) (308). The secure user processor (302) can be comprised of a first trusted microprocessor and a first trusted operating system executing on the first trusted microprocessor. The non-secure user processor (306) can be comprised of a second non-trusted microprocessor and a second non-trusted operating system executing on the second non-trusted microprocessor. A cryptographic engine (304) can be comprised of a third trusted cryptographic processor and a third trusted operating system executing on the third trusted cryptographic processor. The cryptographic engine can be configured for encrypting and decrypting data. A first data communication link (303) communicates data between the secure user processor and the cryptographic engine.
