Abstract: In an example, a computing device is described. The computing device comprises a memory to store a set of states and a corresponding set of non-overlapping time intervals. The computing device further comprises a timing unit to indicate a time at which a signature is to be produced. The computing device further comprises a processor to: identify which time interval of the set of non-overlapping time intervals includes the indicated time; generate a signing key based on a state associated with the identified time interval; and produce a signature, under a stateful signature scheme, with the signing key.

Abstract: An example computing device includes a user interface, a network interface, a non-volatile memory, a processor coupled to the user interface, the network interface, and the non-volatile memory, and a set of instructions stored in the non-volatile memory. The set of instructions, when executed by the processor, is to perform a hardware initialization of the computing device according to a setting, establish a local trust domain and a remote trust domain, use a local-access public key to issue a challenge via the user interface to grant local access to the setting, and use a remote-access public key to grant remote access via the network interface to remote access to the setting.

Abstract: An example computing device includes a memory accessible at startup of the computing device, a buffer, and a set of instructions. The memory stores a configuration setting that is configurable by the application of a change request. The memory also stores a first public key and a second public key. The buffer stores change requests submitted by a remote entity, including a first change request to make a first setting change and a second change request to make a second setting change. The first change request is signed by a first private key corresponding to the first public key, and the second change request is signed by a second private key corresponding to the second public key. The set of instructions retrieves a change request from the buffer, determines whether the change request is authenticated by a public key, and if authenticated, applies the change request.

Abstract: In an example there is provided a method, comprising generating a token in response to an interaction between a user device associated to a user and a service device associated to a service. The token comprises record data indicative of the interaction and verification data to verify the record data. The token is communicated to the user device. The token is stored at the service device. The verification data is generated on the basis of the record data and identification data associated to the user.

Abstract: In an example, a method includes receiving, at a server device, a record of an event transmitted from a client device which occurred on the client device. At the server device, a record of the event is generated, by a processor. The received record is compared with the record generated at the server device. When at least a portion of the record generated at the server device is not found in the received record, an alert is issued.

Abstract: A computing device may receive data associated with an event from an originating apparatus in the form of a data item. The computing device may then apply an evaluation function to the data item, wherein applying the evaluation function generates a processing result characterizing an aspect of the data item. The computing device may generate a tag based on the processing result. The computing device may associate the generated tag with the data, wherein the tag is transmitted with the data outside the network environment where the data item is not accessible for processing outside the network environment, but the data tag is accessible. The computing device may provide the data and the tag for transmission.

Abstract: In an example, a computing device includes a processor which in a reimaging operation of the computing device, may determine if a backup image to be used in the reimaging operation is available from a memory device connected to a local area network of the computing device. When the backup image is available from the memory device, the processor may acquire the backup image over the local area network. When the backup image is not available from the memory device, the processor may determine if a backup image is available from a wide area network of the computing device.

Abstract: In an example, a computing device is described. The computing device comprises a processor. The processor is to generate a key using a value as an input to generate the key. The processor is further to, in response to generating the key, exclude the value from future use as the input. The processor is further to store an indication of a subsequent value to use as the input to generate a subsequent key. The indication is cryptographically associated with an entity to control third-party access to the indication.
