    Hi All,

    ETSI just published ETSI TR 103 616 V1.1.1 Quantum-Safe Signatures

    The purpose of the present document is to give concise descriptions of the six signature schemes remaining in the third
    round of NIST's standardization process. ETSI TR 103 823 [i.45] provides similar descriptions of the nine remaining

    The three digital signature finalists are:
    • Dilithium (see clause 6.1)
    • FALCON (see clause 6.2)
    • Rainbow (see clause 6.3)

    The three digital signature alternate candidates are:
    • GeMSS (see clause 7.1)
    • Picnic (see clause 7.2)
    • SPHINCS+ (see clause 7.3)

    Each of these schemes has a different profile in terms of security properties and performance characteristics, so it is
    expected that some of these schemes will be more suited to specific deployment scenarios than others.
    The descriptions provided in the present document are not intended to be substitutes for the detailed specifications
    submitted to NIST. Instead, the emphasis is on clear mathematical descriptions that facilitate easy comparison of the
    different schemes. Implementation details, such as how to encode polynomials as bit-strings, have been omitted
    wherever possible. As such, some of the descriptions differ from the submitted specifications, in terms of level of
    abstraction, use of notation, and choice of variable names.
