Patent Challenged:

7779252

Description:

Unified Patents is seeking prior art on at least claim 1 of US Patent No. 7,779,252. The patent is owned by NPE, Speir Technologies, an Atlantic IP Services subsidiary. The '252 patent generally relates to a Mobile PDA computer system includes a secure user processor), a non-secure user processor, a cryptographic engine, and a shared human/machine interface (HMI). The secure user processor 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 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 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 communicates data between the secure user processor and the cryptographic engine. A second data communication link communicates data between the cryptographic engine and the non-secure user processor. In this way, the cryptographic engine forms a bridge between the secure user processor and the non-secure user processor. An HMI comprised of trusted hardware for user input and output is time-multiplex-shared among the secure user processor, the non-secure user processor, and the cryptographic engine in a secure fashion.
