Security experts are warning that a security flaw has been found in a popular and powerful data encryption algorithm, dubbed SHA-1, by a team of scientists from Shandong University in China. The three ...

At the Crypto 2004 conference in Santa Barbara, Calif., this week, researchers announced several weaknesses in common hash functions. These results, while mathematically significant, aren’t cause for ...

The National Institute of Standards and Technology (NIST) is conducting a competition to choose a new secure hashing algorithm, and the contest will end Friday, by which time the agency hopes to have ...

Two new IP cores for secure hash algorithm 3 (SHA-3) standard feature more versatile algorithm support. That encompasses support for all four variants of SHA-3 hashing algorithms—224, 256, 384, and ...

The original version of this story appeared in Quanta Magazine. In our increasingly digital lives, security depends on cryptography. Send a private message or pay a bill online, and you’re relying on ...

In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...

We don’t know when, but it will happen: Quantum computers will become so powerful that all existing public-key cryptography protections will be quickly crackable. According to Dr. Mark Jackson of ...

Two researchers have improved a well-known technique for lattice basis reduction, opening up new avenues for practical experiments in cryptography and mathematics. In our increasingly digital lives, ...
