Title: System of enclaves
Inventor: NELLY PORTER
IPC: G06F21/64
Filed: 2017-11-13
Abstract: Root enclave 310, e.g. a trusted execution environment TEE in a private cloud environment, is launched and accesses an enclave manifest 312 specifying a role for each of a plurality of component enclaves 320. Each of the component enclaves 320 are instantiated and the root and component enclaves form an enclave pod e.g. an on premise enclave pod 302 in hybrid cloud enclave 300. First root enclave 310 and first component enclaves 320 are launched according to first manifest 312 and second root enclave 360 and second component enclaves 370 are launched according to second manifest 362. First and second data, which are different, are provided to first and second component enclaves, respectively. Tamper-evident logs may be generated and cryptographically signed. Component enclaves 320 may have a first key, certified by the root enclave 310 using a second key, to securely communicate with other component enclaves 320 of the enclave pod and may ensure that first keys of other component enclaves are also certified by the same second key to share information. Running sensitive execution tasks in enclaves may ensure prevent critical decisions being reverted by untrusted code or root-privileged adversaries in the cloud.

Title: A controller, computer program and method
Inventor: RICHARD COOPER
IPC: H04L45/24
Filed: 2020-01-16
Abstract: A method of calculating a new route for a network media data traffic flow when a device H3 is connected to the network, the network comprising a first and second switches (e.g. S2 and S4) connected by a link, comprises: determining whether media data traffic already flows over the link, towards endpoint H4 for example; applying a weighting (e.g. 0/1000) to the link based on that determination; and determining the new route for media data traffic using a least cost path generation algorithm using the weighting. A minimum spanning tree algorithm, such as Prim’s algorithm, may be used. For unicast traffic, the weighting may be lower if traffic does not flow over the link, and, for multicast traffic, may be lower if traffic already flows over the link to the same IP address as the device being connected. The first and second switches may be updated with the new route using a cookie, which may include a tag value related to the purpose of an associated rule. A further method instead applies a weighting to the link based on the speed of traffic data over the link, and may use a variant of Djikstra’s algorithm to generate a spanning tree.

Title: De-centralised learning for re-identification
Inventor: Shaogong Gong
IPC: G06N20/20
Filed: 2020-01-30
Abstract: A method or system for generating a domain-generalisable model for target re-identification including : optimising a local feature embedding model (FEM) for domain specific feature representation of a client; receiving at a server information about changes to the local FEM; updating at the server a global FEM based on the changes to the local FEM model at a subset of clients; receiving at the client information about the updates to the global FEM; at the client, mapping onto the local FEM and updating the received updates of the global FEM; repeating the previous steps until convergence criteria for the local FEM are met. The global FEM is the optimised domain-generalisable model for target re-identification. The data on local clients may be independent, non-overlapping data sets. White noise may be applied to the local datasets. Because the local data sets are not shared and only changes to the local feature embedding models are shared with the server, the invention may achieve a level of privacy for local datasets.
