Abstract
A device and method are provided for establishing a session key between two entities of a communication network that may be highly heterogeneous in terms of resources. The method, based on the Diffie-Hellman (DH) algorithm, provides for the delegation to assistant nodes of the network of the cryptographic operations required for the computations of the DH public value and of the DH session key for the node which is constrained in terms of resources.
