Abstract—To ensure the quantum security requirement in
internet of things (IoT) scenarios, we first propose certificateless
anti-quantum blind signature (CLAQBS) for blockchain-based
logistics donation system in IoT scenario, its security relies on the
hardness of small integer problem on ring in number theory
research unit lattice; the ethereum lightning network enhances
the transaction speed of consortium blockchain and the rejection
sampling algorithm improves the signature speed; it has short
signature key and high execution efficiency. Then, we propose
certificateless anti-quantum sequential aggregate signature
(CLAQSAS) for IoT intelligent invoice system, the signer
performs sequential aggregate signature on invoice information of
each different goods to generate a new signature; it ensures the
anti-quantum security because of the unique non-sampling
algorithm, trapdoor generation algorithm and matrix preimage
sampling algorithm in lattice.
