A computer-implemented method, in a communication framework in which each of a plurality of users has one or more devices associated therewith, and in which the users use at least some of their devices to communicate via a backend system. A first user has a first set of first one or more associated trusted devices, and a second user has a second set of second one or more trusted devices associated therewith. The first user forms a first cryptographic trust relationship between a first device in the first set and a second device in the second set. Based on (i) the first cryptographic trust relationship, and (ii) the second set associated with the second user, the first user forms corresponding second cryptographic trust relationships between each device in the first set and each device in the second set. A least one device in the first set communicates with one or more devices in the second set based on the second trust relationship.

Trust extension in a secure communication framework

A computer-implemented method, in a communication framework in which each of a plurality of users has one or more devices associated therewith, and in which the users use at least some of their devices to communicate via a backend system. A first user has a first set of first one or more associated trusted devices, and a second user has a second set of second one or more trusted devices associated therewith. The first user forms a first trust relationship between a first device in the first set and a second device in the second set. Based on (i) the first trust relationship, and (ii) the second set associated with the second user, the first user forms a second trust relationship between each device in the first set and each device in the second set. A least one device in the first set communicates with one or more devices in the second set based on the second trust relationship.
