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 ...
Both hashes and salts are key elements in cryptography. A hash function takes an input (such as a master password) and produces a fixed-length string of characters. Meanwhile, a salt is a unique, random value added to the input before it’s hashed.Salting adds an unknown elementand is ...
Similar to leakage-resilient cryptography, tampering attacks are captured by a class of efficient functions named tampering functions, and tampering-resilience is formulated by requiring a cryptographic primitive meet its original security notion even for the attackers having access to a tampered-functionali...
Despite blockchain’s promising features, such as cryptography, digital signatures, hash functions, and decentralisation, blockchain-based IoT networks remain vulnerable to DDoS attacks. Potential anomalous behaviours that manifest as a consequence of a DDoS attack have been evaluated, which can inform ...
As a result, these hash functions are slower and bulkier when compared wit... P Kitsos,B Prasad - International Conference on High Performance Computing 被引量: 3发表: 2007年 Fire ant attacks on residents in health care facilities: A report of two cases. Describes fire ant attacks among ...

In this paper we combine two powerful methods of symmetric cryptanalysis: rotational cryptanalysis and the rebound attack. Rotational cryptanalysis was designed for the analysis of bit-oriented designs like ARX (Addition-Rotation-XOR) schemes. It has been applied to several hash functions and block ci...
