In addition to the full 14-round version, MANTIS<sub>7</sub>, the designers also propose an aggressive 10-round version, MANTIS5. The security claim for MANTIS<sub>5</sub> is resistance against “practical attacks”, defined as related-tweak attacks with data complexity 2<sup>d</sup> less than 2<sup>30</sup> chosen plaintexts (or 2<sup>40</sup> known plaintexts), and computational complexity at most 2<sup>126−d</sup>. We present a key-recovery attack against MANTIS<sub>5</sub> with 2<sup>28</sup> chosen plaintexts and a<br> computational complexity of about 2<sup>38</sup> block cipher calls, which violates this claim. Our attack is based on a family of differential characteristics and exploits several properties of the lightweight round function and tweakey schedule. To verify the validity of the attack, we also provide a practical implementation which recovers the full key in about 1 core hour using 2<sup>30</sup> chosen plaintexts.</p></dct:description> <dct:accessRights rdf:resource="http://publications.europa.eu/resource/authority/access-right/PUBLIC"/> <dct:accessRights> <dct:RightsStatement rdf:about="info:eu-repo/semantics/openAccess"> <rdfs:label>Open Access</rdfs:label> </dct:RightsStatement> </dct:accessRights> <dcat:distribution> <dcat:Distribution> <dct:license rdf:resource="https://creativecommons.org/licenses/by-nc/4.0/legalcode"/> <dcat:accessURL rdf:resource="https://doi.org/10.5281/zenodo.574265"/> </dcat:Distribution> </dcat:distribution> <dcat:distribution> <dcat:Distribution> <dcat:accessURL>https://doi.org/10.5281/zenodo.574265</dcat:accessURL> <dcat:byteSize>514488</dcat:byteSize> <dcat:downloadURL>https://zenodo.org/record/574265/files/TOSC-FSE-Practical-Key-Recovery-TUG.pdf</dcat:downloadURL> <dcat:mediaType>application/pdf</dcat:mediaType> </dcat:Distribution> </dcat:distribution> </rdf:Description> <foaf:Project rdf:about="info:eu-repo/grantAgreement/EC/H2020/644052/"> <dct:identifier rdf:datatype="http://www.w3.org/2001/XMLSchema#string">644052</dct:identifier> <dct:title>HARDWARE ENABLED CRYPTO AND RANDOMNESS</dct:title> <frapo:isAwardedBy> <foaf:Organization> <dct:identifier rdf:datatype="http://www.w3.org/2001/XMLSchema#string">10.13039/501100000780</dct:identifier> <foaf:name>European Commission</foaf:name> </foaf:Organization> </frapo:isAwardedBy> </foaf:Project> </rdf:RDF>
