Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...

Passwords are the keys to our online identities, and as a result, they’re also near the top of the target list for attackers. There have been countless breaches in the last few years in which ...

SHA1, one of the Internet’s most crucial cryptographic algorithms, is so weak to a newly refined attack that it may be broken by real-world hackers in the next three months, an international team of ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...

Researchers have found a new way to attack the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates that secure major websites, making it more urgent than ever to retire it ...

You can’t un-ring a bell, but you might be able to un-hash an email, depending on whom you ask. In order for marketers to safely use hashes for targeted advertising, they must stay abreast of the ...

Cryptographic hash functions secure data by providing a unique fixed-length output for each input. These functions are essential in blockchain for data integrity and secure transactions. Understanding ...

Researchers have produced a collision in iOS’s built-in hash function, raising new concerns about Apple’s CSAM-scanning system — but Apple says the finding does not threaten the integrity of the ...

Phil Goldstein is a former web editor of the CDW family of tech magazines and a veteran technology journalist. He lives in Washington, D.C., with his wife and their animals: a dog named Brenna, and ...
