Patent number: 10936213Abstract: Methods, systems, and devices associated with techniques for secure writes by non-privileged users are described. A memory device may be configured with one or more blocks of memory operating in a secure write mode. The memory device may receive an append command from a non-privileged user. The append command may indicate data to write to the block of memory at an address determined by the memory device. The memory device may identify a pointer to the address for storing the data within the block of memory. The memory device may write the data to a portion of the block of memory based on identifying the pointer and may update the pointer associated with the block of memory based on writing the data.Type: GrantFiled: March 13, 2019Date of Patent: March 2, 2021Assignee: Micron Technology, Inc.Inventors: Olivier Duval, Lance Dover

A programming appliance may receive a command file comprising a first pre-generated digital signature. The first pre-generated digital signature may be associated with a memory system, with a first command and with a first memory system counter value. The programming appliance may send to a memory system a first command message. The first command system may comprise the first command and the first pre-generated digital signature.Type: GrantFiled: August 1, 2018Date of Patent: December 1, 2020Assignee: Micron Technology, Inc.Inventor: Olivier Duval

Publication number: 20200322134Abstract: Systems, methods and apparatuses to configure a computing device for identification and authentication are described. For example, a key management server (KMS) has a certificate generator and is coupled to a registration portal. A copy of secret implemented into a secure component during its manufacture in a factory is stored in the KMS. After leaving the factory, the component can be assembled into the device. The portal receives registration of the component and a hash of software of the device. The certificate generator generates, independent of the device, public keys of the device, using the copy of the secret stored in the KMS and hashes of the software received via the registration portal, and then sign a digital certificate of the public key of the device. Authentication of the device can then be performed via the private key of the device and the certified public key.Type: ApplicationFiled: April 4, 2019Publication date: October 8, 2020Inventor: Olivier Duval

Publication number: 20200245273Abstract: A method is provided for synchronizing timing in phase and frequency of clocks associated with a plurality of radio nodes (RNs) in a small cell radio access network (RAN) having an access controller operatively coupled to each of the RNs. In accordance with the method, a donor list is generated for each given RN in the RAN. The donor list represents an ordered list of potential wireless access points that are able to serve as a source of a wireless sync signal for the given RN. The donor lists are distributed to the respective RNs. An access point is selected by each of the RNs from their respective donor lists to use as a sync signal source. Each of the RNs synchronize their respective clocks in phase and frequency using wireless sync signals received from the respective selected access points.Type: ApplicationFiled: January 28, 2020Publication date: July 30, 2020Inventors: Tsung-YI Chen, Olivier Duval, Hithesh Nama

Patent number: 10645666Abstract: Systems and methods disclosed detect significant changes in the RN topology after an E-RAN system has been installed and provisioned. If a significant change is detected, the operator is notified through an alarm, and the operator can take action to correct it. For example, an RN whose location was moved may be disabled. Alternatively, the movement operation may be approved and the alarm cleared so long as the operation falls within certain approved guidelines or categories, e.g., is appropriately reported and a new location noted.Type: GrantFiled: March 28, 2017Date of Patent: May 5, 2020Assignee: Corning Optical Communications LLCInventors: Ruibin Song, Tsung-Yi Chen, Olivier Duval, Paresh Bhaya

Publication number: 20200073675Abstract: Apparatuses and methods related to concurrently measuring and executing images. An apparatus for concurrently measuring and executing images can include a memory device, a first processing resource and a second processing resource. The first processing resource can execute instructions stored in the memory device to execute a first portion of an image responsive to measuring the first portion of the image and execute a second portion of the image responsive to measuring the second portion of the image. The second processing resource can execute instructions stored in the memory device to measure the first portion of the image and measure the second portion of the image concurrently with an execution of the first portion of the image by the first processing resource.Type: ApplicationFiled: August 31, 2018Publication date: March 5, 2020Inventor: Olivier Duval

Patent number: 10182455Abstract: A method includes obtaining a first packet at a first wireless device from a second wireless device. The second wireless device may be a neighboring wireless device of the first wireless device. The method may also include transmitting a second packet to a third wireless device that is a neighboring wireless device of the first wireless device. The method may also include obtaining a third packet from the third wireless device in response to transmitting the second packet to the third wireless device and obtaining a fourth packet from the third wireless device in response to the third wireless device receiving a fifth packet from a fourth wireless device that is not one of the multiple neighboring wireless devices of the first wireless device. The fourth packet may indicate reserved radio resources for future packet transmissions from the first wireless device to the third wireless device.Type: GrantFiled: May 8, 2014Date of Patent: January 15, 2019Assignee: FUJITSU CONNECTED TECHNOLOGIES LIMITEDInventors: Olivier Duval, Akira Ito
