Abstract

A computer-implemented method of securing communications sent by a first user to a second user may include receiving, by a first user from a trusted third party, at least one public cryptographic value corresponding to the first user and at least one private cryptographic value corresponding to the first user, providing, by the first user to a second user, a plurality of values corresponding to an identification device identified by an identifier, deriving, by the first user, a shared key, using the at least one private cryptographic value of the first user, and at least one of the plurality of values corresponding to the identification device identified by the identifier and protecting communications sent by the first user to the second user with the shared key.
