Abstract
A method for securing communications between a first node (N1) and a second node (N2) in a network (1) further comprising a management device (2) provided with root keying materials, the method comprising the following steps: the management device generating, based on 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 or equal than the total number of sub-elements of the first keying material shares, and the selected sub-elements forming a first node partial keying material shares or symmetric-key generation engine, 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.
