Techniques for provisioning storage may include: initially provisioning storage for a storage group of logical devices; tagging the storage group to enable autonomous storage provisioning; receiving a plurality of parameters used in connection with performing autonomous storage provisioning for the storage group, wherein the plurality of parameters includes a first parameter denoting a threshold amount of consumed storage of the storage group, a second parameter denoting a storage capacity expansion amount by which to expand the storage capacity of the storage group, and a third parameter denoting a system-wide threshold of consumed backend non-volatile storage; determining, in accordance with the plurality of parameters, whether to expand a current storage capacity of the storage group; and responsive to determining to expand the current storage capacity of the storage group, performing first processing to automatically expand the current storage capacity of the storage group in accordance with the second parameter.

A memory controller, which manages a memory device, receives a memory command. The memory controller determines whether the memory command is encrypted. Upon determining that the memory command is encrypted, the memory controller performs a decryption function corresponding to the memory command. Conditioned on the performance of the decryption function resulting in a successful decryption of the memory command, the memory controller performs an operation on a memory location corresponding to a memory address included in the memory command.

Systems, methods, circuits, devices, and apparatus including computer-readable mediums for managing tamper detections in secure memory devices. In one aspect, a secure memory device includes: a memory cell array, one or more tamper detectors each configured to detect a respective type of tamper event on at least part of the secure memory device, and a tamper detection status register storing one or more values each indicating a tamper detection status detected by a corresponding tamper detector. The secure memory device can include a command interface coupled to the tamper detection status register and configured to output the values stored in the tamper detection status register when receiving a trigger. The secure memory device can also include an output pin coupled to the tamper detection status register and be configured to automatically output the values stored in the tamper detection status register via the output pin.

Methods, systems, and devices for secure self-purging memory partitions are described. Systems, techniques and devices are described herein in which data stored in a portion of a secure partition of memory may be removed from the secure partition. In some examples, a portion of secure partition may be allocated as self-purging memory such that data stored therein may be selectively removed in response to a logic address associated with the data being overwritten. In some cases, the data may be removed by programming the memory cells associated with the data to a specific voltage distribution. In some cases, the secure partition may include separate portions having different sets of operating parameters for access operations.

A method including determining, by a first device for a folder, a folder access key pair including a folder access public key and a folder access private key; determining, by the first device, a sharing encryption key based on the folder access private key and an assigned public key associated with a second device; and encrypting, by the first device, the folder access private key based on utilizing the sharing encryption key; determining, by a second device, a sharing decryption key based on the folder access public key and an assigned private key associated with the second device; decrypting, by the second device, the folder access private key based on utilizing the sharing decryption key; and accessing, by the second device, the folder based on utilizing the folder access private key. Various other aspects are contemplated.

Data can be placed by an edge node in a computing environment using multiple criteria in a placement policy. For example, a processing device of an edge node can receive a write request for storing a data object. The processing device can select first and second criteria from a placement policy based on a tag for the data object. The processing device can determine a set of remote components that fulfill the first criterion. The processing device can then identify, from the set, a destination component that fulfills the second criterion. The processing device can transmit the data object to the destination component.

Embodiments of the present disclosure include systems and methods for generating names for cloud storage containers. A unique identifier associated with a user of the client device is received from the client device. Next, a hash value is generated based on the unique identifier associated with the user of the client device. A character encoding scheme is then used to encode the hash value into a first encoded value. Instances of a first character in the encoded value is replaced with a defined second character to form a second encoded value. Finally, the second encoded value is sent to a cloud storage service for the cloud storage service to create a storage container using the second encoded value as a name of the storage container.

There is a possibility that unauthorized writing of adjustment information occurs in a sensor device in which the adjustment information of the sensor device can be written from outside. A sensor device 1 of the present embodiment includes a detection unit 2 configured to detect a physical quantity, a nonvolatile memory 5 configured to store adjustment information 6 and protection information 7, an adjustment unit 3 configured to adjust an output signal of the detection unit 2 based on contents of the adjustment information 6, an output unit 4 configured to output an output of the adjustment unit 3 to an outside via an external terminal 12, a communication unit 11 configured to communicate with the outside of the sensor device 1 via an external terminal 13, a writing unit 8 configured to perform writing process to the nonvolatile memory 6 based on information from the communication unit 11, an erasing unit 9 configured to perform erasing process of the nonvolatile memory 5 based on information from the communication unit 11, and a reading unit 10 configured to perform reading process from the nonvolatile memory 5 based on information from the communication unit 11.
