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 ...

LAS VEGAS—Elie Bursztein, Google's lead anti-fraud researcher, began his talk here at Black Hat 2017 with an understatement: "It has been a long and interesting journey over the last few years." In ...

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 ...

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 ...

SHA-1 is one of the most prevalent forms of a secure hash algorithm used in the legal and security industry. Now that Professor Xiaoyun Wang and her associates in Tsinghua University and Shandong ...

The Tuesday updates for Internet Explorer and Microsoft Edge force those browsers to flag SSL/TLS certificates signed with the aging SHA-1 hashing function as insecure. The move follows similar ...

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 ...

The SHA-256 hash function remains a cornerstone of modern cryptographic systems, underpinning applications ranging from blockchain mining to secure communications in IoT networks. Recent advancements ...

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 ...

Since my start in 2008, I've covered a wide variety of topics from space missions to fax service reviews. At PCMag, much of my work focused on security and privacy services, as well as a video game or ...
