Quantum-safe Signatureless DNSSEC
Abstract
We present $\mathsf{SL\text{-}DNSSEC}$: a backward-compatible protocol that leverages a quantum-safe KEM and a MAC to perform signature-less $\mathsf{(SL)}$ DNSSEC validations in a single UDP query/response style. Our experiments targeting NIST level I security for QTYPE A query resolution show that $\mathsf{SL\text{-}DNSSEC}$ is practically equivalent to the presently deployed RSA-2048 in terms of bandwidth usage and resolution speeds. Compared to post-quantum signatures, $\mathsf{SL\text{-}DNSSEC}$ reduces bandwidth consumption and resolution times by up to $95\%$ and $60\%$, respectively. Moreover, with response size $<$ query size $\leq 1232$ bytes, $\mathsf{SL\text{-}DNSSEC}$ obviates the long-standing issues of IP fragmentation, TCP re-transmits and DDoS amplification attacks.
