Patent number: 9501652Abstract: 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).Type: GrantFiled: January 22, 2015Date of Patent: November 22, 2016Assignee: Texas Instruments IncorporatedInventors: Erdal Paksoy, Narendar Shankar, Sven-Inge Redin

Patent number: 8978146Abstract: 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.Type: GrantFiled: March 8, 2011Date of Patent: March 10, 2015Assignee: Texas Instruments IncorporatedInventors: Erdal Paksoy, Narendar Shankar, Sven-Inge Redin
