This year, SCHUTZ­WERK is not only a spon­sor of Elb­si­des, but will also hold a talk on June 22, 2021 at 4:10 p.m. The topic of our col­le­ague Dr. Hen­ning Kopp will be “Pad­ding Ora­cle At­tacks - The cri­ti­cal bug in your ho­me-bre­wed cryp­to pro­to­col”.

Pad­ding ora­cle at­tacks are a com­mon im­ple­men­ta­ti­on weak­ness in en­cryp­ti­on al­go­rithms. An in­for­ma­ti­on dis­clo­sure re­gar­ding the pad­ding, e.g., via error me­sa­ges or run time dif­fe­ren­ces in the exe­cu­ti­on of the al­go­rithm can lead to a full de­cryp­ti­on.

We are very much loo­king for­ward to the event and will be avail­able in the SCHUTZ­WERK-chan­nel in the BSi­des­ME­s­h21-Slack chan­nel for ques­ti­ons and ex­ch­an­ge on June 22nd from 1 p.m. to 6 p.m.
