A team of researchers from the U.S., Switzerland, and the Netherlands successfully forged some trusted SSL certificates with the help of 200 PS3's cluster.

At issue is the crypto technology used to ensure visitors to Amazon.com, for example, are actually connected to the online retailer and not to a fake site erected by a fraudster. That assurance comes from a digital certificate that’s vouched for and digitally signed by a trusted authority like Verisign. The certificate is transmitted to a user’s browser and automatically verified during SSL connections — the high-security web links heralded by a locked-padlock icon in the browser.

Key to the signing process is a so-called hash function — an algorithm that turns a digital file into a small fingerprint of a fixed size. To prevent forgery, the hash function must make it practically impossible for anyone to create two files that will boil down to the same hash.

The researchers have also released a diagram showing us how their method works:

They plan to release their full details on how the executed there method soon.
