Principal and auxiliary submitters: Sedat Akleylek, Erdem Alkim, Paulo Barreto, Nina Bindel, Johannes Buchmann, Edward Eaton, Gus Gutoski, Juliane Krämer, Patrick Longa, Harun Polat, Jefferson Ricardini, and Gustavo Zanon

The submission of the lattice-based digital signature scheme qTESLA includes three folders:

• "KAT": Contains the Known Answer Tests
• "Reference_implementation": Contains the reference implementation
• "Additional_implementations/avx2": Contains the AVX2-optimized implementation

Subfolder "KAT":

• "\ref\PQCsignKAT_qTesla-p-I.rsp" : Known answer test results for qTesla-p-I, ref implementation
• "\ref\PQCsignKAT_qTesla-p-III.rsp" : Known answer test results for qTesla-p-III, ref implementation
• "\avx2\PQCsignKAT_qTesla-p-I.rsp" : Known answer test results for qTesla-p-I, AVX2 implementation
• "\avx2\PQCsignKAT_qTesla-p-III.rsp" : Known answer test results for qTesla-p-III, AVX2 implementation

Subfolder "Reference_implementation":

• "qTesla-p-I" : Reference implementation of qTesla-p-I with parameters for NIST’s security category 1
• "qTesla-p-III" : Reference implementation of qTesla-p-III with parameters for NIST’s security category 3

Subfolder "Additional_implementations/avx2":

• "qTesla-p-I" : AVX2-optimized implementation of qTesla-p-I with parameters for NIST’s security category 1
• "qTesla-p-III" : AVX2-optimized implementation of qTesla-p-III with parameters for NIST’s security category 3
