Abstract
A hybrid cryptographic scheme for a network of nodes, in particular an IoT network, composed of a first subset and a second subset of separate nodes, the computing resources of the nodes of the first subset being greater than the computing resources of the nodes of the second subset, the scheme comprising a first functional cryptographic scheme deployed on the first subset of nodes and a second functional cryptographic scheme deployed on the second subset of nodes, a cryptographic primitive at the root of the second cryptographic scheme generating a pair of private and public master keys from a seed, the seed being obtained by a connection cryptographic primitive from at least the private key of an end node of the first subset, the connection cryptographic primitive being a one-way function.
