arXiv:2610.32356v1 Announce Type: new Abstract: Post-quantum key encapsulation mechanisms carry public keys far larger than the established VPN handshake protocol IKEv2 was designed for. At the same time, its initial exchange comprising the public keys cannot be fragmented. In response, the IETF discusses a range of protocol adjustments, yet these proposals have never been compared in terms of their performance and stability under identical conditions.
