Therefore, these cryptographic tools are designed in order to satisfy the desired properties The methods for analyzing hash functions, or attacks shortly, can be classified in various types according to the main
At ASIACRYPT 2007, Knudsen and Rijmen introduced known-key security of blockciphers, which gave rise to many distinguishing attacks on existing blockcipher constructions. In this work, we analyze the impact of such attacks on primitive-based hash functions. We present and formalize the weak cipher...
In this paper, we analyze the security of RIPEMD-128 against collision attacks. The ISO/IEC standard RIPEMD-128 was proposed 15 years ago and may be used as a drop-in replacement for 128-bit hash functions like MD5. Only few results have been published for RIPEMD-128, the best being a ...
People have already tried to use SAT solvers to break cryptographic hash functions, but you do eventually hit a limit on the feasible problem size. MILP Mixed-integer linear programming (MILP) is a form of optimization where the optimization variables may be integer-valued, rather than the ...
With each extra digit added to the hash, the odds of creating a matching one decrease significantly. 20. Malware attack Malware is a general term for malicious software, hence the “mal” at the start of the word. Malware infects a computer and changes how it functions, destroys data, ...
In [88], a decentralized method is proposed to authenticate vehicles using hash functions. The Two-Factor LIghtweight Privacy-preserving (2FLIP) algorithm works in two steps to provide fast and accurate authentication. In the first step, a thematic device is used to identify the driver using fi...
Rainbow table attacks where attackers use a rainbow table – a precomputed table/ dictionary of plaintext passwords and hash functions corresponding to them. Using the rainbow table, they try to reversecryptographichash functions. Reverse brute force attacks where attackers use common/known passwords or...
Let be a family of universal hash functions. Then for arbitrarily random variables , it holds that where and . This lemma states that a family of universal hash functions gives an average-case -strong randomness extractor as long as . 2.3. Key-homomorphic hash proof systems We present the no...

Stored XSS attacks usually occur on websites that permit content sharing, such as forums, blogs, and message boards. If a website has vulnerabilities and fails to validate user input thoroughly, it becomes vulnerable to exploitation by attackers. Attackers use functions such as posting, commenting...
