POST-QUANTUM AUTHENTICATION WITH PROBABILISTIC DATA STRUCTURES

原文（中国語）

A method for generating a digital signature for a message involves obtaining the message and a signing private key. The signing private key is divided into a plurality of indexed values. A counter value is identified to provide a set of partitions with unique integer interpretations through at least one round of combining the message with the counter value, hashing the combined message and counter value to generate a hash, reducing the hash to a predetermined length to generate a reduced hash, and partitioning the reduced hash into a plurality of partitions. If the partitions are not interpretable as a set of unique integers, the counter value is incremented for the next round. If the partitions are interpretable as a set of unique integers, the counter value is provided. A set of values from the signing key indexed by the unique integers is selected, and the digital signature comprising the selected set of values and the counter is outputted.
