A method for data processing is performed by an operation data recording device. The method includes: in response to a data access request sent by a client for a target vehicle, generating symmetric keys for symmetrically encrypting operation data of the target vehicle, in which the symmetric keys are generated based on a user ID and a primary public key for a third party, and the user ID is carried in the data access request; obtaining target encrypted data by symmetrically encrypting the operation data using the symmetric keys; and sending the target encrypted data to the client.

Methods and apparatus to enable a distinction between “new” and “used” digital content and to enable a market in used digital content files between mobile phone terminals and an electronic store, securely, by means of a wireless telephony network and a server complex to handle contents right management, transaction reporting, inventory, content delivery, payment, and billing. A server receives a signal generated by a wireless user device that was sent over a wireless telephony network. The signal indicates an election for returning at least one previously purchased digital content item. The server deletes user rights for the at least one digital content item identified by the received signal and sends information to the user device that generated the signal. Access to the associated digital content item at the user device is removed according to the sent information.

A cloud-based system for securely storing data, the system having a processor which obtains a source data file; splits it into at least three fragments; and uses an encryption key associated with the fragments to encrypt the fragments and distributes the encrypted fragments among at least three cloud storage providers, creates a pointer file containing information for retrieving the encrypted fragments. When a system user requests access to the data, the system uses the information stored in the pointer file to retrieve the stored encrypted fragments from the plurality of clouds; decrypts the fragments and reconstructs the data, and provides data access to the system user.

Disclosed is a computer-implemented method for establishing a secure connection between two electronic computing devices which are located in a network environment, the two electronic computing devices being a first computing device offering the connection and a second computing device designated to accept the connection, the method comprising executing, by at least one processor of at least one computer, a connection-establishing application for exchanging an information packet between the first computing device and the second computing device comprising a secret usable for establishing the connection, and evaluating a response from the second computing device for establishing the secure connection.

Provided is an authentication device capable of generating a master key suited to a UE in a 5GS. The authentication device (10) includes a communication unit (11) configured to, in registration processing of user equipment (UE), acquire UE key derivation function (KDF) capabilities indicating a pseudo random function supported by the UE, a selection unit (12) configured to select a pseudo random function used for generation of a master key related to the UE by use of the UE KDF capabilities, and a key generation unit (13) configured to generate a master key related to the UE by use of the selected pseudo random function.

Techniques for computer security, and more specifically timestamp-based key generation techniques, are described. Some implementations provide a table of key generation processes that is shared as a secret between a first computing system and a second computing system, both of which have synchronized clocks. Both computing systems use the same technique for selecting a key generation process from the table, such as based on a random number generator seeded with a timestamp. Since the computing systems have synchronized clocks, they both select and use the same key generation process, thereby generating the same encryption key without the need to communicate the key from one system to another. Furthermore, both computing systems may synchronize their clocks to a private time server that maintains a clock that runs faster or slower than standard time. Security is maintained by one or more of restricting access to the time server, using secret key generation processes, and/or using a secret random number generator.

A method may include sending, to a provisioning service and by an application executing on a virtual machine, a local authentication token for a user of the virtual machine. The provisioning service may use the local authentication token to generate a portable access token. The method may further include receiving, from the provisioning service, the portable access token, and launching, by the application and for the user, a session in a web service by sending the portable access token to an application programming interface (API) of the web service.

A system including a mobile terminal having an authenticator, a TPM with tamper resistance and a voice assistant. The voice assistant makes a process request corresponding to voice input of a user to a server in accordance with the input, receives a biometric authentication request from the server, makes a request for a biometric authentication process to the mobile terminal of the user in accordance with the request for biometric authentication via wireless communication, and transmits an authentication result from the mobile terminal to a server. The mobile terminal executes the biometric authentication process using biometric information stored in the authenticator and the TPM in accordance with the request for the biometric authentication process from the voice assistant, and transmits an authentication result to the voice assistant.

A cloud-based system for securely storing data, the system having a processor which obtains a source data file; splits it into at least three fragments; and uses an encryption key associated with the fragments to encrypt the fragments and distributes the encrypted fragments among at least three cloud storage providers, creates a pointer file containing information for retrieving the encrypted fragments. When a system user requests access to the data, the system uses the information stored in the pointer file to retrieve the stored encrypted fragments from the plurality of clouds; decrypts the fragments and reconstructs the data, and provides data access to the system user.

A command to load or unload data at a storage location is received. In response to the command, a storage integration object associated with the storage location is identified. The storage integration object identifies a cloud identity object that corresponds to a cloud identity that is associated with a proxy identity object corresponding to a proxy identity granted permission to access the storage location. The data is loaded or unloaded at the storage location by assuming the proxy identity.
