Under an adaptive chosen ciphertext attack (CCA2), the security of an encryption scheme must hold against adversaries that have access to a decryption oracle. We consider a weakening of CCA2 security, wherein security need only hold against adversaries making an a-priori bounded number of queries to the decryption oracle. Concerning this notion, which we call bounded-CCA2 security, we show the ...

Abstract Food values are supposed to be stable. This paper tests this assumption by comparing food before and during the coronavirus-19 pandemic. While ranking of remains very similar, there some interesting differences in relative importance that consumers attached A substantial decrease attach safety was observed pandemic, while a moderate increase taste, nutrition, appearance, convenience or...

Abstract Nativism is one of the defining phenomena contemporary era. Yet, we know little about how malleable citizen attitudes associated with nativism and nationalism are to priming effects when media frames which deal key issues such as immigration introduced. In this article, present findings from a survey experiment fielded nationally representative sample voters in Australia May 2019. it, ...

Due to the simplicity and performance of zk-SNARKs they are widely used in real-world cryptographic protocols, including blockchain smart contract systems. Simulation Extractability (SE) is a necessary security property for NIZK argument achieve Universal Composability (UC), common requirement such protocols. Most works that investigate SE focus on its strong variant which implies proof non-mal...

In this dissertation, I propose that, post-action, people tend to be more optimistic about outcomes when their actions were based on malleable (vague) information compared to when their actions were based on unmalleable (precise) information. However, pre-action, no such difference occurs. I term this inconsistency in optimism in the pre and post-action stage, the Information Malleability Effec...

Current theories of emotion perception posit that basic facial expressions signal categorically discrete emotions or affective dimensions of valence and arousal. In both cases, the information is thought to be directly ‘‘read out’’ from the face in away that is largely immune to context. In contrast, the three studies reported here demonstrated that identical facial configurations convey striki...
