BBB Secure Arbitrary Length Tweak TBC from n-bit Block Ciphers [PDF]
At FSE\u2715, Mennink introduced the concept of designing beyond-the-birthday bound secure tweakable block cipher from an ideal block cipher. They proposed two tweakable block ciphers $\widetilde{F}[1]$ and $\widetilde{F}[2]$ that accepts $n$-bit tweak ...

Ethnographies of Human‐AI Collaborations: What Arrangements of Expertise Emerge?
Sociology Compass, Volume 20, Issue 9, September 2026.ABSTRACT In this review, I outline four arrangements on the spectrum of human experts‐AI collaboration, as studied from an ethnographic, grounded perspective by sociology, management, and STS scholars. Starting with the sociology of expertise's definitions of what constitutes “expert work,” I first review cases in which AI almost replaced human ...

Localization sequences for logarithmic topological cyclic homology
Journal of Topology, Volume 19, Issue 3, September 2026.Abstract We introduce the notion of an Ek$\mathbb {E}_k$‐ring with prelogarithmic structure, define logarithmic topological Hochschild homology and logarithmic topological cyclic homology in this context, and establish localization sequences for these theories. Our approach is based on Thom R$R$‐algebras.

The MALICIOUS Framework: Embedding Backdoors into Tweakable Block Ciphers [PDF]
Lecture Notes in Computer Science, 2020 Inserting backdoors in encryption algorithms has long seemed like a very interesting, yet difficult problem. Most attempts have been unsuccessful for symmetric-key primitives so far and it remains an open problem how to build such ciphers.

Tweakable Block Ciphers Secure Beyond the Birthday Bound in the Ideal Cipher Model [PDF]
Lecture Notes in Computer Science, 2018 We propose a new construction of tweakable block ciphers from standard block ciphers. Our construction, dubbed \(\mathsf {XHX2}\), is the cascade of two independent \(\mathsf {XHX}\) block ciphers, so it makes two calls to the underlying block cipher using tweak-dependent keys.
