Practical free-start collision attacks on 76-step SHA-1 [PDF]
, 2015 In this paper we analyze the security of the compression function of SHA-1 against collision attacks, or equivalently free-start collisions on the hash function.

American Journal of Industrial Medicine, Volume 66, Issue 2, Page 109-121, February 2023., 2023 Abstract Background The Occupational Safety and Health Administration (OSHA) implemented a new standard in 2014 requiring employers to report nearly all work‐related inpatient hospitalizations within 24 h of the event. We examined the characteristics of the injured workers who were reported and the compliance of Michigan employers with the regulation ...

Preimage and pseudo collision attacks on round-reduced DHA-256 hash function
Tongxin xuebao, 2013 A preimage attack on DHA-256 hash function reduced to 37-round and a pseudo collision attack on the func-tion reduced to 39-round were proposed respectively.Based on the meet-in-the-middle attack,the Biclique technique was used to improve the preimage ...

Attack Prevention for Collaborative Spectrum Sensing in Cognitive Radio Networks [PDF]
, 2011 Collaborative spectrum sensing can significantly improve the detection performance of secondary unlicensed users (SUs). However, the performance of collaborative sensing is vulnerable to sensing data falsification attacks, where malicious SUs (attackers) submit manipulated sensing reports to mislead the fusion center's decision on spectrum occupancy ...

On the Design of Secure and Fast Double Block Length Hash Functions [PDF]
, 2008 In this work the security of the rate-1 double block length hash functions, which based on a block cipher with a block length of n-bit and a key length of 2n-bit, is reconsidered.

A Practical Collision-Based Power Analysis on RSA Prime Generation and Its Countermeasure
IEEE Access, 2019 We analyze the security of RSA prime generation implemented on embedded devices by a practical power analysis attack. Unlike previous differential power analysis-based attack on primality tests of RSA prime generation exploiting the deterministic ...

A Meaningful MD5 Hash Collision Attack [PDF]
, 2006 It is now proved by Wang et al., that MD5 hash is no more secure, after they proposed an attack that would generate two different messages that gives the same MD5 sum. Many conditions need to be satisfied to attain this collision.

Arthritis Care &Research, EarlyView.Objective Osteoporosis, a known complication of rheumatoid arthritis (RA), increases the risk of hip fracture, which is associated with high morbidity and mortality. Fracture risk estimates in patients with RA treated with contemporary treatment strategies are lacking.

IACR Transactions on Symmetric Cryptology, 2016 In this paper, we describe attacks on the recently proposed Haraka hash functions. First, for the two hash functions Haraka-256/256 and Haraka-512/256 in the family, we show how two colliding messages can be constructed in about 216 function ...
