Abstract
An electronic key pre-distribution device for configuring multiple network nodes with local key information is provided. The key pre-distribution device applies at least a first hash function and a second hash function to a digital identifier of a network node. The first and second hash functions map the digital identifier to a first public point and a second public point on a first elliptic curve and second elliptic curve. A first and second secret isogeny are applied to the first and second public elliptic curve points, to obtain a first private elliptic curve point and second private elliptic curve point that are part of private key material for the network node.
