  • ELLIPTIC CURVE ISOGENY BASED KEY AGREEMENT PROTOCOL
    Publication number: 20230336346
    Abstract: An electronic key pre-distribution device (110) for configuring multiple network nodes (210, 211) with local key information is provided. The key pre-distribution device comprises applies at least a first hash function (147) and a second hash function (148) to a digital identifier of a network node. The first and second hash functions map the digital identifier to a first public point (141; H1(ID)) and a second public point (142; H2(ID)) on a first elliptic curve (131) and second elliptic curve (132). A first and second secret isogeny (135) is applied to the first and second public elliptic curve point (141, 142), to obtain a first private elliptic curve point (151) and second private elliptic curve point (152) being part of private key material (155) for the network node (210).
