Title: Detecting targeted data exfiltration in encrypted traffic
Inventor: BLAKE HARRELL ANDERSON
IPC: H04L29/06
Filed: 2019-06-12
Abstract: A service that monitors a network obtains file characteristic data of a file stored on a first endpoint in the network. The service infers characteristics of encrypted content within encrypted traffic in the network between the first endpoint and a second endpoint, by applying a machine learning-based classifier to traffic data regarding the encrypted traffic session. The service compares the file characteristic data of the file to the inferred content characteristics of the encrypted content within the encrypted traffic, to detect the file within the encrypted traffic. The service enforces a network policy in the network, based on the detection of the file within the encrypted traffic. The arrangement allows detection of protected or sensitive files or malicious traffic being sent by the first endpoint within encrypted traffic sent by the first endpoint. The policy may comprise blocking, slowing or redirecting, for example, the encrypted traffic. File size, user identifiers, file name, file directory information etc may be used as file characteristics. The service may be performed by a traffic analysis service (408, Figure 4A).

Title: Electric vehicle charging system
Inventor: SIMON WHITE
IPC: H02J7/00
Filed: 2020-07-31
Abstract: An electric vehicle (EV) charging system includes: a central control module 1 that distributes electricity from a power distribution network to at least one local charging feed, and houses a central controller in communication with a communications network; and at least one local charging module 18, remote from the central control module. When charging two EVs 19 at a local charging module, the module is identified to an authorisation system and an authorisation signal is received at the central controller. A signal is received at the local charging module that a first EV is connected to a first charging outlet 23 at the local charging module. In response to the authorisation signal, a central switch, coupled to the local charging feed, is closed and electricity flows between the central control module and the local charging module to initiate charging of the first EV. These steps are repeated for a second EV at a second charging outlet at the local charging module. Charging of the first EV is paused, pending a verification signal from the central controller that an authorisation signal has been received. If so, each EVs is charged using charging cycles, wherein electricity to the first and second charging outlets is switched on and off for scheduled time periods, to alternate “pausing charging” and “charging” until at least one of the EVs has reached a desired charge.
