Abstract:
1. A method for securing communications between a first node and a second node in a network comprising a management device provided with root keying materials, the method comprising: the management device generating, based on the root keying materials, a first node keying material shares comprising a number of sub-elements and the first node keying material shares being arranged for generating a first complete key, the management device selecting a subset of sub-elements of the first keying material shares, the number of sub-elements selected being less than the total number of sub-elements of the first keying material shares, and the selected sub-elements forming a first node symmetric-key generation engine, the management device distributing the first node symmetric-key generation engine to the first node, and the first node generating, based on the first node symmetric-key generation engine and on an identifier of the second node, a first key used for securing communications with the second node.
