Australian Journal of Social Issues, EarlyView.ABSTRACT As modes of activism rapidly evolve, activists—both seasoned and emerging—must increasingly navigate a hybrid terrain of both digital and non‐digital engagement. This paper draws on the personal narratives of 16 nascent activists based in Australia to explore how they develop competencies related to digital storytelling, which is critical to ...

Generic Universal Forgery Attack on Iterative Hash-based MACs [PDF]
, 2014 . In this article, we study the security of iterative hash-based MACs, such as HMAC or NMAC, with regards to universal forgery attacks. Leveraging recent advances in the analysis of functional graphs built from the iteration of HMAC or NMAC, we exhibit ...

Forgery Attacks on Several Beyond-Birthday-Bound Secure MACs
, 2023 At CRYPTO’18, Datta et al. proposed nPolyMAC and proved the security up to 22𝑛/3 authentication queries and 2𝑛 verification queries. At EUROCRYPT’19, Dutta et al. proposed CWC+ and showed the se- curity up to 22𝑛/3 queries. At FSE’19, Datta et al. proposed PolyMAC and its key-reduced variant 2k-PolyMAC, and showed the security up to 22𝑛/3 queries. This

A Statistical Approach for Keystroke Continuous Authentication Subversion
IEEE AccessContinuous Authentication systems leveraging keystroke dynamics are increasingly used to verify users unobtrusively. However, the resilience of these systems against advanced adversarial techniques remains unclear.

Breaking into the KeyStore: A Practical Forgery Attack Against Android KeyStore [PDF]
, 2016 We analyze the security of Android KeyStore, a system service whose purpose is to shield users credentials and cryptographic keys. The KeyStore protects the integrity and the confidentiality of keys by using a particular encryption scheme. Our main results are twofold. First, we formally prove that the used encryption scheme does not provide integrity,

Angewandte Chemie International Edition, EarlyView.The first catalytic asymmetric formal [3+2] cycloaddition of allylsilanes delivers cis‐2,5‐disubstituted tetrahydrofuran‐3‐ones that serve as versatile intermediates for the synthesis of diverse bioactive scaffolds. ABSTRACT A formal [3+2] cycloaddition via cyclization/1,2‐hydride shift initiated by nucleophilic attack of allylsilanes has been ...

Forgery and Key Recovery Attacks on PMAC and Mitchell’s TMAC Variant [PDF]
, 2006 In this paper we discuss the security of PMAC, a provably secue and parallelizable MAC scheme proposed by Black and Rogaway, and Michell's TMAC variant, proposed to improve the security of TMAC. We show how to devise forgery attacks on PMAC and compare the success rate of our forgery attacks with their security bound. We also present forgery attacks on

A practical forgery and state recovery attack on the authenticated cipher PANDA-s [PDF]
, 2014 PANDA is a family of authenticated ciphers submitted to CARSAR, which consists of two ciphers: PANDA-s and PANDA-b. In this work we present a state recovery attack against PANDA-s with time complexity about $2^{41}$ under the known-plaintext-attack model,

The LOCAL attack: Cryptanalysis of the authenticated encryption scheme ALE [PDF]
, 2013 We show how to produce a forged (ciphertext, tag) pair for the scheme ALE with data and time complexity of 2102 ALE encryptions of short messages and the same number of authentication attempts.
