Round optimal blind signatures
WebIn particular, round optimal (i.e., 2-move) blind signature schemes have re-ceived attention since the round complexity is an important measurement of ef- ciency in the computer network, and round optimal blind signature schemes di-rectly imply that they are concurrently secure. In the random oracle model, there are elegant round optimal blind ... WebKnown constructions of blind signature schemes suffer from at least one of the following limitations: (1) rely on parties having access to a common reference string or a random …

WebApr 10, 2015 · However, most blind signature schemes based on factoring and discrete logarithm problems cannot resist quantum computer attacks. The alternative blind signature schemes are based on lattice. Here, we present a round-optimal lattice-based blind signature scheme constructed on the closest vector problem using infinity norm. WebAug 1, 2024 · Since most concurrent blind signature and round-optimal blind signature schemes were constructed on the factoring or the DLP, these schemes were nonresistant to quantum-computer attacks [39]. The demand for strong resistance to quantum computer attacks and high efficiency leads to the alternative blind signature schemes based on …
