A two‐step authentication framework for Mobile ad hoc networks [PDF]
, 2007 The lack of fixed infrastructure in ad hoc networks causes nodes to rely more heavily on peer nodes for communication. Nevertheless, establishing trust in such a distributed environment is very difficult, since it is not straightforward for a node to ...

The nearly Newtonian regime in Non-Linear Theories of Gravity
, 2005 The present paper reconsiders the Newtonian limit of models of modified gravity including higher order terms in the scalar curvature in the gravitational action. This was studied using the Palatini variational principle in [Meng X. and Wang P.: Gen. Rel.

International Journal of Climatology, Volume 45, Issue 9, July 2025.The onset of the rain season in Thailand in the late April–early May is highly predictable from ending ENSO events. The predictability is highly non‐stationary from 1950 due to subtle changes during warm ENSO events, which last longer and are more intense from 1980 onward.

Amplified Boomerang Attacks Against Reduced-Round MARS and Serpent [PDF]
, 2001 We introduce a new cryptanalytic technique based on Wagner's boomerang and inside-out attacks. We first describe this new attack in terms of the original boomerang attack, and then demonstrate its use on reduced-round variants of the MARS core and Serpent. Our attack breaks eleven rounds of the MARS core with 265 chosen plaintexts, 270 memory, and 2229

War as a continuation of politics by other means... unmanned [PDF]
Janus.net, 2014 The growth of US combat capability due to the operational introduction of drones is the most significant of any weapon system in recent decades. Under this new operating model, the drones are proliferating a myriad of essential activities in the battle ...

A new S-box pattern generation based on chaotic enhanced logistic map: case of 5-bit S-box
CybersecurityCryptography plays consistently an essential role in securing any sort of communications or data broadcast over the network. Since the security of any designed block cipher algorithm is related to its Substitution box (S-box), several efforts have been ...

A Holistic Framework for Impossible Boomerang Attacks
IACR Communications in CryptologyIn 2011, Lu introduced the impossible boomerang attack at DCC. This powerful cryptanalysis technique combines the strengths of the impossible differential and boomerang attacks, thereby inheriting the advantages of both cryptographic techniques. In this paper, we propose a holistic framework comprising two generic and effective algorithms and a MILP ...

The Boomerang Attack on 5 and 6-Round Reduced AES [PDF]
, 2005 In this note we study security of 128-bit key 10-round AES against the boomerang attack. We show attacks on AES reduced to 5 and 6 rounds, much faster than the exhaustive key search and twice faster than the “Square” attack of the AES designers. The attacks are structural and apply to other SPN ciphers with incomplete diffusion.

The Boomerang Attacks on BLAKE and BLAKE2 [PDF]
, 2015 In this paper, we study the security margins of hash functions BLAKE and BLAKE2 against the boomerang attack. We launch boomerang attacks on all four members of BLAKE and BLAKE2, and compare their complexities. We propose 8.5-round boomerang attacks on both BLAKE-512 and BLAKE2b with complexities \(2^{464}\) and \(2^{474}\) respectively.
