ABSTRACT:
A cryptographic communications method is provided which is based on ID-NIKS and is resilient to collusive attack. Centers (1) established in a plurality generate secret keys peculiar to entities (a, b) using division vectors wherein specifying information (ID information) for said entities is divided and personal secret random numbers set differently for each component in the division vectors. The centers (1) then distribute the secret keys to the entities. The entities generate common keys using components, contained in their own peculiar secret keys, that correspond to the division vectors of other entities. Each division vector is configured with codewords of an error correcting code.
