  • Patent number: 9501652
    Abstract: An electronic circuit 120 includes a more-secure processor (600) having hardware based security (138) for storing data. A less-secure processor (200) eventually utilizes the data. By a data transfer request-response arrangement (2010, 2050, 2070, 2090) between the more-secure processor (600) and the less-secure processor (200), the more-secure processor (600) confers greater security of the data on the less-secure processor (200). A manufacturing process makes a handheld device (110) having a storage space (222), a less-secure processor (200) for executing modem software and a more-secure processor (600) having a protected application (2090) and a secure storage (2210).

  • Patent number: 8978146
    Abstract: An electronic circuit includes a more-secure processor having hardware based security for storing data. A less-secure processor eventually utilizes the data. By a data transfer request-response arrangement between the more-secure processor and the less-secure processor, the more-secure processor confers greater security of the data on the less-secure processor. A manufacturing process makes a handheld device having a storage space, a less-secure processor for executing modem software and a more-secure processor having a protected application and a secure storage. A manufacturing process involves generating a per-device private key and public key pair, storing the private key in a secure storage where it can be accessed by the protected application, combining the public key with the modem software to produce a combined software, signing the combined software; and storing the signed combined software into the storage space.

  • Patent number: 8812804
    Abstract: A secure demand paging (SDP) system includes a dynamic random access memory (DRAM), a microprocessor having a secure internal memory and coupled to said DRAM, and a non-volatile memory storing a representation of operations accessible by the microprocessor. The stored representation of operations includes a coded physical representation of operations to configure an SDP space in the DRAM, to organize the SDP space into virtual machine contexts, to organize at least one of the virtual machine contexts into block book keeping blocks and book keeping spaces in the block book keeping blocks, and to execute a secure demand paging process between said secure internal memory and said DRAM.
