Abstract: In one example of the disclosure, an encrypted document and an encryption key for decrypting the encrypted document are received from a computer. Presence data for a printer is received via a first wireless network. A user instruction to print the encrypted document at the printer is received. A credential is received from the printer via the first wireless network, where the credential for communication with the printer via a second wireless network with greater bandwidth than the first wireless network. The encrypted document and the encryption key are sent to the printer, where the printer is to utilize the encryption key to decrypt the encrypted document and is to print the document following decryption.

Abstract: A memory device includes a non-volatile memory to store data, an execution trace buffer, and a media controller. The media controller receives data-modifying commands and adds the data-modifying commands to the execution trace buffer. The media controller executes the data-modifying commands to modify the data stored in the non-volatile memory and detects errors in the data stored in the non-volatile memory. The media controller repeats execution of data-modifying commands from the execution trace buffer in response to detecting an error.

Abstract: In some examples, an electronic device of a localization system comprises a wireless transceiver to exchange data with a mobile device and a processor. The electronic device obtains, from the mobile device, location coordinates of the mobile device. The location coordinates of the mobile device are set as location coordinates of the electronic device. A beacon package comprising an identifier of the electronic device and the location coordinates of the electronic device is generated. The beacon package is transmitted to a local device in proximity to the electronic device.

Abstract: Examples associated with storage monitoring are described. One example system includes generating an encryption key and transmitting the encryption key to a basic input/output system (BIOS) security module. The BIOS security module uses the encryption key as a basis for a heartbeat. A provisioning module receives a signal identifying a monitored storage and generates an enforced storage associated with the monitored storage. The provisioning module also creates a manifest describing the relationship between the enforced storage and the monitored storage. The provisioning module transmits the manifest to the BIOS security module. A versioning module assigns a first access policy for the monitored storage and a second access policy to the enforced storage based on the manifest. The versioning module performs versioning for the monitored storage using the enforced storage, and periodically verifies operation to the BIOS security module using the heartbeat.

Abstract: Examples associated with cryptographic key security are described. One example system includes a secure storage accessible to a basic input/output system (BIOS). A BIOS security module stores an authorization value in a fixed location in the secure storage. The authorization value is stored by the BIOS during a boot of the system. A cryptographic key module reads the authorization value from the fixed location, overwrites the authorization value in the fixed location, and obtains a cryptographic key using the authorization value.

Abstract: Example implementations relate to meeting passcodes. In an example, meeting passcodes can employ a meeting hub including an antenna and a controller coupled to the antenna to wirelessly receive, via the antenna, information including a first meeting passcode from a meeting device, generate a second meeting passcode in response to receipt of the first meeting passcode, cause the second meeting passcode to be sent to a registered user of meeting device, and admit the meeting device to a meeting using the second meeting passcode.
