Providing secure secrets for encryption consistency enables rotating security measures (e.g., encryption access keys in users' certificate) for encrypted data at rest, without either needing to retain any prior certificates or requiring decryption and re-encryption. This provides enhanced security over some prior art methods (old keys may be discarded) and enhanced speed over the other prior art methods (no decryption / re-encryption needed). Examples generate a primary encryption key, which is retained on a secure remote computing node, such as in a key vault, and is not shared outside the key vault. Access to the primary encryption key is restricted to users who possess the current encryption access key, which is rotated on some trigger event. The remote node receives incoming messages to encrypt or decrypt files and performs the encryption / decryption using the primary - but only if a message contains the current encryption access key. Rotating the encryption access key preserves security.

The invention relates to a wearing tightness identification method and device of wearable equipment, equipment and a medium. The method comprises the steps that static data and action data of a target user wearing the wearable device are obtained, the static data are data collected when the target user does not do limb actions, and the action data are data collected when the target user does limb actions; and based on the static data and the action data, identifying the wearing tightness of the wearable device. According to the invention, the accuracy of the wearing tightness can be improved.

A cloud service is configured to receive a request from a mobile device requesting for authenticating the mobile device for receiving personal health data from a wearable device that is registered with the cloud service. In response to successful authentication, the cloud service sends a secondary character to the mobile device, which in turn passes the secondary character to the wearable device. In response to successful verification of the secondary character, the cloud service receives encrypted personal health data generated from the mobile device. The cloud service stores the encrypted personal health data at rest. When the cloud service provides the personal health data to a user, the cloud service decrypts the data and re-encrypts it with a different encryption mechanism, and sends the re-encrypted data to the user.

The invention relates to the technical field of acceleration sensor calibration, in particular to equipment for calibrating acceleration data of a sensor and a use method of the equipment. Comprising the steps of collecting acceleration and real displacement data of a sensor under four typical working conditions of static, constant speed, uniform acceleration and variable acceleration; zero offset is estimated and coordinate system parameters are discriminated through static data, and gravity decoupling and deviation correction are carried out on dynamic data; a displacement truth value is synchronously obtained by combining a photoelectric sensor, a graduated scale and a camera, and multi-source data time sequence offset is eliminated by using a time axis alignment algorithm; a three-axis scale factor and a drift parameter are cooperatively calibrated under multiple working conditions, and the calibration precision is improved through high-pass filtering and direction path optimization; and generating a calibration packet containing a zero offset, a scale factor and a filtering parameter for online or offline compensation. Through multi-excitation fusion, dynamic gravity elimination and time sequence accurate alignment, the checking accuracy and environmental adaptability of acceleration data are remarkably improved, and reliable support is provided for high-precision displacement measurement.

The present disclosure relates to devices and methods for protecting data from physical attacks. The devices and methods can establish an encryption protocol to encrypt data sent over a bus to one or more removable devices in communication with a computer device. The devices and methods can communicate with the removable devices using the encryption protocol and perform storage requests at the removable devices. The devices and methods can also perform another layer of encryption on data stored on the removable devices using a data at rest key stored on the removable devices.

Present invention relates to systems and methods for calculation of information and cyber risk posed by the systems and methods that process data and their automated non-compliance verification and information and cyber risk posed by non-compliance. Disclosed is a system (100) and a method (200) for calculation of information and cyber risk by identifying sensitive electronic information stored in client devices (10) like desktops, laptops, mobile devices and databases of shared network drives or cloud environments connected through a communication network (20). The system (100) is capable of identifying the data at rest stored in various file formats such as word, excels, csv, pdf, power point, database file formats and compressed file formats. The method (200) calculates information and cyber risk and there identifies the potential liability or insurance value based on volume and value of data and compliance with corporate policies for data protection and potential areas of non-compliance.

A memory subsystem includes link encryption for the system memory data bus. The memory controller can provide encryption for data at rest and link protection. The memory controller can optionally provide link encryption. Thus, the system can provide link protection for the data in transit. The memory module can include a link decryption engine that can decrypt link encryption if it is used, and performs a link integrity check with a link integrity tag associated with the link protection. The memory devices can then store the encrypted protected data and ECC data from the link decryption engine after link protection verification.

This document relates to secure storage techniques that can be employed in a multi-tenant environment. In the disclosed implementations, a host CPU can perform data at rest encryption on data that is written to an SSD via an interposer. By offloading the data at rest encryption from the interposer to the CPU, the complexity and power consumption of the interposer can be reduced. Furthermore, redundant cryptographic operations can be mitigated, because the interposer and CPU do not necessarily perform link encryption on data payloads themselves. Rather, link encryption can be limited to associated command data used to configure transfers of encrypted data payloads.
