Patent number: 9767303Abstract: Systems and methods that can facilitate the utilization of a memory as a slave to a host are presented. The host and memory can provide authentication information to each other and respective rights can be granted based in part on the respective authentication information. The host can determine the available functionality of the memory. The host can activate the desired functionality in the memory and can request memory to perform the desired function(s) with regard to data stored in the memory. An optimized controller component in the memory can facilitate performing the desired function(s) associated with the data to generate a result. The result can be provided to the host, while the data and associated information utilized to generate the result can remain in the memory and are cannot be accessed by the host.Type: GrantFiled: February 14, 2014Date of Patent: September 19, 2017Assignee: MONTEREY RESEARCH, LLCInventors: Christophe Carvounas, Joël LeBihan

Patent number: 8650399Abstract: Systems, devices and/or methods that facilitate mutual authentication for processor and memory pairing are presented. A processor and a suitably equipped memory can be provided with a shared secret to facilitate mutual authentication. In addition, the memory can be configured to verify that the system operating instructions have not been subjected to unauthorized alterations. System integrity can be ensured according to the disclosed subject matter by mutual authentication of the processor and memory and verification of the authenticity of system operating instructions at or near each system power up. As a result, the disclosed subject matter can facilitate relatively low complexity assurance of system integrity as a replacement or supplement to conventional techniques.Type: GrantFiled: February 29, 2008Date of Patent: February 11, 2014Assignee: Spansion LLCInventors: Joël Le Bihan, Christophe Carvounas, Vincent Cedric Colnot, Elena Trichina, Helena Handschuh

Patent number: 7558907Abstract: The claimed subject matter can provide an architecture that can transparently provide more robust interactions between a host device and a smartcard or other mass media storage device by way of block level read or write operations provided as part of a standard interface protocol. A virtual controller can be installed on the smartcard to manage access to the data store of a smartcard. The virtual controller can provide special objects (e.g., files, directories, partitions . . . ) to the host, and upon an access to one of these special files, call an application to manage pre- or post-processing of the data transferred between the host and the smartcard.Type: GrantFiled: October 13, 2006Date of Patent: July 7, 2009Assignee: Spansion LLCInventors: Julien Stern, Christophe Carvounas, Cedric Colnot, Nicolas Prawitz, Jean-Yves Grall, Thomas Pornin
