At the 25th Chaos Communication Congress (CCC) today, researchers will reveal how they utilized a collision attack against the MD5 algorithm to create a rogue certificate authority. This is pretty big ...

In general, unless you're specifically tailoring input to produce collisions, collision risk of a (formerly, in case of md5 and by now also sha1) cryptographically secure hash function is not ...

Researchers have demonstrated new collision attacks against SHA-1 and MD5 implementations in TLS, IKE and SSH. If you’re hanging on to the theory that collision attacks against SHA-1 and MD5 aren’t ...

If you thought MD5 was banished from HTTPS encryption, you’d be wrong. It turns out the fatally weak cryptographic hash function, along with its only slightly stronger SHA1 cousin, are still widely ...

Using computing power from a cluster of 200 PS3 game consoles and about $700 in test digital certificates, a group of hackers in the U.S. and Europe have found a way to target a known weakness in the ...

RADIUS is a common user authentication protocol used for network connections. It was originally developed in 1991 with dial-up connections in mind, but at the time of writing, it is supported by ...

A powerful digital certificate that can be used to forge the identity of any website on the internet is in the hands of in international band of security researchers, thanks to a sophisticated attack ...

The old and insecure MD5 hashing function hasn’t been used to sign SSL/TLS server certificates in many years, but continues to be used in other parts of encrypted communications protocols, including ...

The MD5 collision attack used by the creators of the Flame malware was significantly more difficult to pull off than an earlier attack that resulted in the creation of a rogue CA certificate, says ...
