Cryptographers Dimitri Koshelev, a postdoctoral researcher at the Universitat de Lleida's Cryptography and Graphs group who also holds an affiliation with the Institute of Mathematics at the National ...

Cryptographic hash functions are widely used in many aspects of security, such as digital signatures and data integrity checks. The short digital fingerprint generated from an electronic file, message ...

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 ...

For more than six years, the SHA1 cryptographic hash function underpinning Internet security has been at death’s door. Now it’s officially dead, thanks to the submission of the first known instance of ...
