摘要： A system for a secured communication between a computer and peripheral devices includes a fiber isolator transmitter coupled to a computer and one or more fiber-optic pairs; a fiber isolator receiver coupled to one or more peripheral devices and the one or more fiber-optic pairs; and the one or more fiber-optic pairs configured to transfer optical data signals between the fiber isolator transmitter and the fiber isolator receiver. The fiber isolator transmitter and the fiber isolator receiver are configured so corresponding video data and audio data flows from the computer to a corresponding display device(s) and/or speaker(s), respectively, of the one or more peripheral devices via one optical fiber of a corresponding fiber optic pair of the one or more fiber-optic pairs and USB data flow from the one or more peripheral devices to the corresponding computer via a particular optical fiber of the one or more fiber optic pairs.

摘要： A dispensing device (100) an operating system (13) for controlling a product and access means (15) that selectively provide a user with access to the product. The access devices receive an dispense request (25) from a user's personal access device (20,22) and route it to the operating system (13). The access means include identification means (16,17) to generate a unique request identifier with the dispense request and are capable of cryptographically encrypting the dispense request (25) together with the unique request identifier (∑,ID) into a cryptographically encrypted dispense request (35). The operating system (13) is coupled with decryption and validation means (50,55) capable and configured to decrypt the cryptographically encrypted dispense request (35) and derive the unique request identifier (∑,ID) from it. The decryption and validation agents validate the decrypted dispense request (25) based on the unique request identifier (∑,ID) and will value the decrypted request identifier as being valid only once.

摘要： A single input/output (I/O) controller for both secure partitionable endpoints (PEs) and non-secure PEs is enabled in a trusted execution environment (TEE) where secure memory portions are isolated from non-secure PEs. Security attributes for certain endpoints indicate secure memory access privilege of owning entities of the certain endpoints. A security monitor has exclusive access to the address translation control tables (TCE) stored in secure memory associated with a secure endpoint. When owning entity reassignment occurs, the endpoints are reinitialized to support a change in ownership from an outgoing owning entity having secure memory access and an incoming owning entity not having secure memory access.

摘要： Un procédé de contrôle d'accès à un support de stockage via un bus de communication comporte la réception (E11), via le bus de communication, d'un ensemble de signaux électriques comportant un signal électrique représentatif d'une commande d'opération destiné à mettre en œuvre une opération sur au moins une zone du support de stockage. Le procédé de contrôle comporte en outre : - la vérification (E2) de la valeur d'au moins un paramètre relatif à au moins un signal électrique de l'ensemble de signaux électriques reçu; et - l'autorisation (E31) ou le refus (E32) de la mise en œuvre de la commande d'opération sur ladite au moins une zone du support de stockage, en fonction du résultat de ladite vérification (E2).

摘要： Systems and techniques are described for implementing testing-and-manufacturing keys for a system-on-chip (SoC). A hardware test portion of the SoC is configured to exercise features of domains that process data being communicated across the fabrics during an externally initiated test. In response to receiving a testing-and-manufacturing token from an external test system, a testing- and-manufacturing key support component of the SoC generates a testing-and-manufacturing key. The hardware test portion is configured to execute a test function to promote security of the SoC, however, only in response to the testing-and-manufacturing security component authenticating the testing-and-manufacturing key. Through implementing testing-and-manufacturing keys this way, the system-on-chip secures access to potentially sensitive functions and secrets, while allowing their unencumbered and authorized access for testing the system-on-chip during various life cycle states.

摘要： A method for determining authenticity of a component in an imaging device is disclosed. Embodiments of the present disclosure provide for a method for a device to use an electronic authentication scheme to authenticate a second device while overcoming vulnerabilities associated with sending data over a communication bus when performing authentication, by using information other than that transmitted over the shared bus as authentication parameters. Embodiments utilize the current drawn by a chip from a powder source when the chip performs an operation in response to a command as an authentication parameter.

摘要： Access permissions are set for different requesting circuits on a control bus. The access permissions can be set by the level 1 manager and the level 2 manager, allowing two layers of security to be added. The level 1 manager has priority, allowing it to add access permissions that cannot be removed by the level 2 manager.

摘要： A micro data capture device can be configured to operate as a unidirectional connection from a first computing device to a second computing device. The micro data capture device can include a data capture side comprising a first universal serial bus (USB) interface configured to connect to the first computing device so as to extract data from the first computing device. The micro data capture device can further include a monitoring apparatus comprising an interceptor configured to copy data from the data capture side so as to define the unidirectional connection. Further, the micro data capture device can define a data storage side comprising a second USB interface configured to connect to the second computing device so as to transfer data to the second computing device. The data storage side can be configured to receive data from the data storage side via the monitoring apparatus. In some cases, the data capture side has only volatile memory, and the data storage side includes non-volatile memory. Further, the data capture side can be physically separate from the data storage side.
