Abstract
Mobile PDA computer system () includes a non-secure processor (), comprising an untrusted microprocessor and an untrusted operating system executing on the untrusted microprocessor. The system also includes a secure processor (), comprising a trusted microprocessor and a trusted operating system executing on the trusted microprocessor. A cryptographic engine () is provided for encrypting and decrypting data. A first data communication link () communicates data between the secure processor and the cryptographic engine. A second data communication link () communicates data between the non-secure processor and the cryptographic engine. In this way, the cryptographic engine forms a bridge between the secure user processor and the non-secure user processor.
