New Constructions of MACs from (Tweakable) Block Ciphers
IACR Transactions on Symmetric Cryptology, 2017 We propose new constructions of Message Authentication Codes (MACs) from tweakable or conventional block ciphers. Our new schemes are either stateless and deterministic, nonce-based, or randomized, and provably secure either in the standard model for ...

The costs of Suaahara II, a complex scaled-up multisectoral nutrition programme in Nepal. [PDF]
Matern Child NutrSuaahara II, a scaled up multisectoral nutrition programme in Nepal, cost US$132 per programme participant (mother in the 1000‐day period). Opportunity costs of volunteer and participant time are high, accounting for 47% of total costs. Complex multisectoral programmes require significant resources to ensure coordination and support at national and ...

Multi-User BBB Security of Public Permutations Based MAC [PDF]
, 2022 At CRYPTO 2019, Chen et al. have shown a beyond the birthday bound secure $n$-bit to $n$-bit PRF based on public random permutations. Followed by the work, Dutta and Nandi have proposed a beyond the birthday bound secure nonce based MAC $\textsf{nEHtM}_p$

Double-block Hash-then-Sum: A Paradigm for Constructing BBB Secure PRF
IACR Transactions on Symmetric Cryptology, 2018 SUM-ECBC (Yasuda, CT-RSA 2010) is the first beyond birthday bound (BBB) secure block cipher based deterministic MAC. After this work, some more BBB secure deterministic MACs have been proposed, namely PMAC_Plus (Yasuda, CRYPTO 2011), 3kf9 (Zhang et al ...

People and Nature, EarlyView.Abstract Tree‐planting initiatives are a crucial part of international sustainability and climate action efforts. Yet, many of these initiatives fail to achieve their long‐term sustainability and climate goals. The role of community value is an often‐overlooked factor in promoting the success of new tree plantings.
