This work exploits internal differentials within a cipher in the context of Differential Fault Analysis (DFA). This in turn overcomes the nonce barrier which acts as a natural counter-measure against DFA. We introduce the concept of internal differential fault analysis which requires only one faulty ciphertext. In particular, the analysis is applicable to parallelizable ciphers that use the cou...

In this paper we obtain a weakness in the design specification of ACORN, which is a competitor of CAESAR competition. We show that there exists a probabilistic linear relation between message bits and ciphertext bits, which holds with probability greater than 12 . This is the first paper which finds a probabilistic linear relation between message and corresponding ciphertext bits of ACRON, and ...

Robots are able to enter concealed and unstable environments inaccessible to rescuers. Previous Urban Search And Rescue (USAR) robots have experienced problems with malfunction of communication systems, traction systems, control and telemetry. These problems were accessed and improved in developing a prototype robot called CAESAR, which is an acronym for Contractible Arms Elevating Search And R...

BACKGROUND The new REACH legislation requires assessment of a large number of chemicals in the European market for several endpoints. Developmental toxicity is one of the most difficult endpoints to assess, on account of the complexity, length and costs of experiments. Following the encouragement of QSAR (in silico) methods provided in the REACH itself, the CAESAR project has developed several ...

In this paper we experiment with cube testers on reduced round Trivium that can act as a distinguisher. Using heuristics, we obtain several distinguishers for Trivium running more than 800 rounds (maximum 829) with cube sizes not exceeding 27. In the process, we also exploit state biases that has not been explored before. Further, we apply our techniques to analyse Trivia-SC, a stream cipher pr...

Caesar is a distributed, social code review tool designed for the specific constraints and goals of a programming course. Caesar is capable of scaling to a large and diverse reviewer population, provides automated tools for increasing reviewer efficiency, and implements a social web interface for reviewing that encourages discussion and participation. Our system is implemented in three loosely-...

ASCON is one of the elegant designs authenticated encryption with associated data (AEAD) that was selected as first choice for lightweight applications in CAESAR competition, which also has been submitted to NIST cryptography standardization. literature a while; however, there no successful AEAD secure and at same time lighter than ASCON. In this article, we have overcome challenge constructing...
