Abstract: A method comprising, at a processor-controlled device, obtaining encrypted data comprising an encrypted data portion, obtaining an identifier indicative of a characteristic associated with the processor-controlled device, and performing a decryption process. The decryption process comprises decrypting the encrypted data portion to generate a decrypted data portion, and generating decrypted data comprising the decrypted data portion and an identifying portion based on the identifier.

Abstract: A method includes, at a processor-controlled device of a network, identifying a first portion of a data transmission transmitted via the network that is indicative of an anomaly. A second, different, portion of the data transmission including personal data is identified. The data transmission is modified to generate a modified data transmission, the modifying the data transmission comprising selectively anonymizing one or more portions of the data transmission such that at least the second portion of the data transmission is anonymized. The modified data transmission is sent to a remote system for identification of whether the first portion of the data transmission is indicative of malicious behavior.

Abstract: The present disclosure relates to securing networks against attacks launched via connection of peripheral devices to networked devices.

Abstract: Improvements to publish-subscribe protocols are provided, including a method for communicating data in a network comprising publisher devices, a broker and subscriber devices, comprising one of the publisher devices: i-a. receiving a public key from the broker; i-b. determining, based on one or more attributes of data to be published to the broker, whether a sensitivity level of the data is low; and ii. following completion of both of steps i-a and i-b, publishing the data to the broker, wherein: when step i-b results in a determination that the sensitivity level of the data is low, step ii comprises transmitting the data to the broker unencrypted; and when step i-b results in a determination that the sensitivity level of the data is not low, step ii comprises encrypting the data then transmitting resulting encrypted data to the broker, wherein the step of encrypting the data uses the public key.
