摘要： Security measures for signal paths with tree structures can be implemented at design phase using an EDA software program or tool with security feature functionality that, when executed by a computing system, directs the computing system to: display a canvas through which components of a circuit are arranged; and provide a menu of commands, including an option to add components from a library to the canvas and an option to secure a tree. In response to receiving a selection of the option to secure the tree, the system can be directed to add a hardware countermeasure coupled to at least two lines or terminal nodes of a tree structure identified from components on the canvas or in a netlist corresponding to a circuit's design.

摘要： A data access manager is provided on a computing device to manage access to secure files stored in memory. The data access manager intercepts function calls from applications to the memory management unit and determines whether an application is allowed to access secure data stored in the memory of the computing device. When an initial request to map the data is received, the data access manager maps both secure data and clear data, obtaining pointers to both secure and clear data. When an application has permission to access the requested data, the data access manager returns the pointer to the clear data. When an application does not have permission to access the requested data, the data access manager returns the pointer to the secure data.

摘要： Technologies for secure I/O include a compute device having a processor, a memory, an input/output (I/O) device, and a filter logic. The filter logic is configured to receive a first key identifier from the processor, wherein the first key identifier is indicative of a shared memory range includes a shared key identifier range to be used for untrusted I/O devices and receive a transaction from the I/O device, wherein the transaction includes a second key identifier and a trust device ID indicator associated with the I/O device. The filter logic is further configured to determine whether the transaction is asserted with the trust device ID indicator indicative of whether the I/O device is assigned to a trust domain and determine, in response to a determination that the transaction is not asserted with the trust device ID indicator, whether the second key identifier matches the first key identifier.

摘要： A method for data isolation in a multi-tenant environment includes a vault API that is programmed to generate a key ID corresponding to a client ID associated with received entity data and pass an encryption request to a separate computer system that generates a data key to encrypt the entity data. The encrypted data is then returned to the vault API that then stores the encrypted data in a client collection associated with the client ID.

摘要： A method for a smart device management resource picker includes receiving an authorization request from a third party. The authorization request requests access to a user resource managed by the device manager. The device manager manages access controls associated with a plurality of user devises, the access controls are configured by a user. The method also includes determining whether the third party is authorized to access the user resource managed by the device manager. When the third party is authorized to access the user resource managed by the device manager, the method includes determining whether the user has configured access controls at the device manager that governs the user resource subject to the authorization request. When the user has configured a respective access control that governs the user resource subject to the authorization request, the method includes communicating a response to the authorization request based on the respective access control.

摘要： Disclosed are a data reading method, a storage medium, and a mobile terminal. The method is applied to the mobile terminal. The method comprises: acquiring private data from a preset application program; backing up the private data to a device encryption storage area of the mobile terminal that is in a boot mode; and when the preset application program is run, if the mobile terminal is in the boot mode, reading the private data from the device encryption storage area.
