Abstract given by the source: For nyligt blev det annonceret at nogen havde konstrueret kvantecomputere. Selvom det er usikkert helt, hvor store sådanne maskiner vil blive, er det sikkert, at eksistensen af dem vil have en dramatisk effekt på sikkerheden af de kryptografiske systemer, som bliver brugt overalt i dag. Indtil nu har dette været kendt for de såkaldte public-key kryptosystemer. Nye resultater viser imidlertid, at sikkerheden af de såkaldte symmetriske systemer også er i fare, når kvantecomputere bliver bygget. Målet med dette projekt er at udvikle nye, symmetrisk kryptografiske algoritmer, som giver øget sikkerhed mod angreb implementeret på kvantecomputere, men samtidig bibeholder de effektivitetskrav, som nutidens anvendelser kræver. Helt konkret vil det resultere i forslag til fleksible, effektive og kvante-sikre blokkrypteringssystemer, MAC-systemer og autentificerede krypteringssystemer.
