    <subfield code="a">&lt;p&gt;Bu teknik notta, DKLS&amp;nbsp;imza protokol&amp;uuml; adımlarının dikkatli bir şekilde uygulanmaması (implementasyonu) durumunda ortaya &amp;ccedil;ıkabilecek bir zafiyet, yani bilinen&amp;nbsp;&lt;em&gt;selective abort/selective failure&lt;/em&gt;&amp;nbsp;saldırısı, detaylı bir şekilde ele alınacaktır. Bu t&amp;uuml;r zafiyetler, protokol&amp;uuml;n entegrasyonunu kolaylaştırmak ve performansını artırmak amacıyla, protokol&amp;uuml;n kriterlerine tam uyum&amp;nbsp;sağlanmadan eksik ya da hatalı bir şekilde uygulanmasından kaynaklanmaktadır. Daha a&amp;ccedil;ık bir ifadeyle, bu teknik notta, DKLS&amp;nbsp;imza şemasının temelini oluşturan OT (Oblivious Transfer) protokol&amp;uuml;nde, bazı girdi parametrelerinin her imza i&amp;ccedil;in değiştirilmek yerine tekrar tekrar kullanılması durumunda &amp;ouml;zel anahtarın a&amp;ccedil;ığa &amp;ccedil;ıkmasına ait analiz detaylı bir şekilde a&amp;ccedil;ıklanacaktır.&lt;/p&gt;</subfield>
