Revisiting Gilbert’s known-key distinguisher

Known-Key Distinguisher on Full PRESENT

In this article, we analyse the known-key security of the standardized PRESENT lightweight block cipher. Namely, we propose a knownkey distinguisher on the full PRESENT, both 80and 128-bit key versions. We first leverage the very latest advances in differential cryptanalysis on PRESENT, which are as strong as the best linear cryptanalysis in terms of number of attacked rounds. Differential prop...

Distinguisher and Related-Key Attack on the Full AES-256

In this paper we construct a chosen-key distinguisher and a related-key attack on the full 256-bit key AES. We define a notion of differential q-multicollision and show that for AES-256 q-multicollisions can be constructed in time q · 2 and with negligible memory, while we prove that the same task for an ideal cipher of the same block size would require at least O(q · 2 q−1 q+1 ) time. Using si...

revisiting the authority of “alidjma almadraki” (idjma with known origins)

non-authority of “alidjma almadraki” (idjma with known origins) is a topic frequently raised in the usulis’ contemporary literature. in this paper, the authority of “alidjma almadraki” has been studied through revisiting this idjma since the introduction of idjma in general by shia scholars up to the present. the results of this study show that based on all foundations raised to prove the autho...

Improved Single-Key Distinguisher on HMAC-MD5 and Key Recovery Attacks on Sandwich-MAC-MD5

Revisiting Known-Item Retrieval in Degraded Document Collections

Optical character recognition software converts an image of text to a text document but typically degrades the document’s contents. Correcting such degradation to enable the document set to be queried effectively is the focus of this work. The described approach uses a fusion of substring generation rules and context aware analysis to correct these errors. Evaluation was facilitated by two publ...
