Abstract: A method for verifying the integrity of data in a message by a data processing device, the message comprising a plurality of packets, the method comprising: receiving, at the device from a first resource, a manifest associated with the message, the manifest comprising a plurality of group check values for the plurality of packets; receiving, at the device, from the first or a different resource, the message; generating a first progression of rolling hashes for the plurality of packets; deriving group check values from the first progression of rolling hashes for groups of the plurality of packets along one or more paths; verifying the integrity of the data in the message based on or in response to a determination that the derived group check values correspond to the plurality of group check values in the manifest.

Abstract: A machine-implemented method for controlling a configuration data item in a storage-equipped device having at least two security domains, comprising receiving, by one of the security domains, a configuration data item; storing the configuration data item; providing a security indication for the configuration data item; and when an event indicates untrustworthiness of the data item, invalidating a configuration effect of the stored configuration data item. Further provided is a machine-implemented method for controlling a storage-equipped device as a node in a network of devices, comprising receiving information that a data source or type of a configuration data item is untrusted; analysing metadata for the data source and the configuration data item; populating a knowledge base with analysed metadata; and responsive to the analysed metadata, transmitting security information to the network of devices. A corresponding device and computer program product are also described.

Abstract: A method for securely distributing content from a distributor to a plurality of receiving devices, each recipient creating recipient trusted ephemeral public private key pair and making the recipient trusted ephemeral public key available, the method comprising: generating a content encryption key for encrypting content to be distributed and encrypting content using the content encryption key; generating, for each recipient trusted ephemeral public key, a shared secret using the recipient trusted ephemeral public key and the distributor ephemeral private key; generating a plurality of encrypted per-recipient key slots, each encrypted per-recipient key slot generated by encrypting the content encryption key using a different shared secret of the plurality of shared secrets; creating a data structure comprising the distributor ephemeral public key, the encrypted content, and one or more encrypted per-recipient key slots; and transmitting the data structure to deliver the content to recipients associated with the device public keys from which the one or more encrypted per-recipient key slots are derived.
