Described herein is a technique to update an edge device deployed in a secure computing network. A repository connected to a public network stores build contents configured to update software installed on the edge device; the public network is inaccessible to devices within the secure computing environment. A second device connected to the public network acquires the build contents in a signed lockbox file. An edge device management service generates a lockbox file containing the build contents and a trusted signer outside the secure computing network signs the lockbox file. The second device connects to secure computing network and establishes communications with the edge device. The edge device verifies the signed lockbox file provided by the second device. Upon verification, the edge device extracts the contents of the signed lockbox file and updates the software installed on the edge device.

Methods, systems, and machine-readable mediums that enhance transaction authentication of a transaction of a first application by checking that a state of one or more other applications matches prespecified states or that one or more of those applications transition states within a prespecified period of time. For example, the prespecified states may correspond to the application being installed on a specified device (e.g., of the user) and having an authenticated session with a specified user.

This invention discloses a secure file transmission method based on low-entropy segmented credentials and stateless relay, comprising a sender client, a receiver client, and a relay server. After file verification, the sender client generates a transmission code, which consists of a search code and a key code. The sender client transmits the transmission code to the receiver out-of-band. The receiver client reconstructs the derived search code from the transmission code, calculates the derived key, and thus reconstructs and decrypts the complete encrypted file to obtain the plaintext file. The relay server provides key-value pair-based data storage services; it only needs to provide the block search code as the key to address and return data blocks. This invention provides a secure file transmission method based on low-entropy segmented credentials and stateless relay. The values ​​in the relay server are not the complete encrypted file, and there is no obvious logical relationship between the key-value pairs, effectively weakening the impact of low-entropy credentials on security.

This application discloses a memory manager power-off recovery method and electronic device, relating to the computer field. It achieves exclusive access to memory resources by initiating the process with a persistent trigger signal and combining it with a global mutex lock, ensuring the consistency of core data acquisition. The acquired data is structured and written to a dump file to construct a verifiable persistent carrier.
