Systems and techniques for vehicle distributed computing for on-demand computational capacity. Systems and techniques described herein enable distribution of discrete computational work requests to other vehicle systems through generation and awarding of smart contracts to locally positioned other vehicle systems bidding for the smart contracts. Data for processing the requests is encrypted and send to the vehicle winning the smart contract, which processes the request and returns the completed work product. Completion of the smart contract initiates transfer of value to the processing vehicle as incentive for processing the work load.

An electronic apparatus includes a communication interface, a memory; and a processor. The memory is configured to store a hypervisor. The processor is configured to obtain an authentication key for performing authentication of an external device. The processor is also configured to encrypt the authentication key based on a key pre-stored in the memory using the hypervisor and store the encrypted authentication key in the memory. Based on a request for information that is stored in the memory being received from the external device, the processor is configured to perform authentication of the external device using the hypervisor. Based on the authentication of the external device being completed, the processor is configured to control the communication interface to transmit the stored information to the external device.

A service processor is provided that includes a processor, a memory coupled to the processor and having instructions for executing an operating system kernel having an integrity management subsystem, secure boot firmware, and a tamper-resistant secure trusted dedicated microprocessor. The secure boot firmware performs a secure boot operation to boot the operating system kernel of the service processor. The secure boot firmware records first measurements of code executed by the secure boot firmware when performing the boot operation, in one or more registers of the tamper-resistant secure trusted dedicated microprocessor. The operating system kernel enables the integrity management subsystem. The integrity management subsystem records second measurements of software executed by the operating system kernel, in the one or more registers of the tamper-resistant secure trusted dedicated microprocessor.

A system includes a plurality of data input ports, each port corresponding to one of a plurality of different levels of security classification; a security device, configured for cryptographic processing, coupled to receive incoming data from each of the plurality of input ports, wherein the incoming data includes first data having a first classification level; a key manager configured to select and tag-identified first set of keys from a plurality of key sets, each of the key sets corresponding to one of the different levels of security classification, wherein the first set of keys is used by the security device to encrypt the first data; and a common encrypted data storage, coupled to receive the encrypted first data from the security device for storage.

An access revocation system for removing user data from a service provider device includes a processing device and a memory storing instructions for performing an access revocation method. The method includes receiving user data from a user device via a data channel, storing the user data in a data storage module, and receiving an access revocation message via a request channel separate from the data channel. The method also includes decrypting the access revocation message and performing at least one action defined by the access revocation message, the at least one action including scrubbing of user data from the data storage module.

Aspects of the invention include detecting that a rekey timer has expired. The rekey timer is one of a shared key rekey timer for a current shared key between the first node and a second node, and a session key rekey timer for a session key used in a secure communication between a channel on the first node and a channel on the second node. The session key was created based on the current shared key and is used for encrypting data in the secure communication. Based on the rekey timer being the shared key rekey timer, a new shared key is obtained and stored as the current shared key. Based on the rekey timer being the session key rekey timer, a new session key that is based at least in part on the current shared key is obtained and used in the secure communication.

Methods and systems for sharing a network link of a file in network storage for collaboration among multiple computing devices using end-to-end encryption may involve generating a link key associated with the file stored remotely in the network storage, being accessible by a first device, and to be accessible by a second device, encrypting a session key associated with the file to generate an encrypted session key using the link key, the file being encrypted with the session key and, generating a salt associated with the file, generating a verifier associated with the file using the link key, sending a message to a server computer with an identifier associated with the file, the salt, the verifier, and the encrypted session key, creating a first link to the file with a name associated with the first device, the identifier, and the link key, and transmitting the first link to second device.

A method including receiving, at a processor, a first assigned public key from a first device included in a mesh network and an external assigned public key from an external device not included in the mesh network; determining, by the processor, that the external device is to be included in the mesh network based at least in part on determining an association between the first device and the external device; and transmitting, by the processor based at least in part on determining that the external device is to be included in the mesh network, the first assigned public key to the external device and the external assigned public key to the first device to enable the first device and the external device to set up a meshnet connection. Various other aspects are contemplated.

Systems and methods are described for implementing load-dependent encryption mechanism selection in an elastic computing system. The elastic computing system can include a set of host devices configured to implement block storage volumes on behalf of users. Users may desire that such volumes be encrypted prior to storing data. It may be generally preferable for encryption to occur on the same host devices that host the volume, to reduce latency and bandwidth usage needed to encrypt the data. However, encryption of data can utilize significant computational resources, which may not be available on host devices that also have sufficient storage resources to host the volume. The present disclosure describes systems and methods that can account for computational resource availability on host devices, selecting “in-place” encryption only when available resources exist on host devices, and otherwise implementing remote encryption of volume data.

The present disclosure discloses a device binding method and device, used to resolve the issue of the prior art in which the operation of controlling a smart device in a certain position is cumbersome. The method of embodiments of the present disclosure comprises: a user terminal sending target address information to a server, the server encrypting the target address information, generating a verification password, and sending the verification password to the user terminal; the user terminal sending, by means of a transmission device, the verification password to a device to be bound; the device sending the received verification password and a device identifier of the device to the server; and if the verification password sent by the device is the same as the verification password generated by the server, the server binding the target address information corresponding to the received verification password to the device identifier.
