How the ECDSA Algorithm Works by PS3 Developer KaKaRoToKS

1350°
135w ago - Following up on his status update for the PS3 4.0 Homebrew Enabler (HEN), today Sony PlayStation 3 hacker KaKaRoToKS has explained how the ECDSA algorithm works.

To quote: To popular demand, I have decided to try and explain how the ECDSA algorithm works. I've been struggling a bit to understand it properly and while I found a lot of documentation about it, I haven't really found any "ECDSA for newbies" anywhere.

So I thought it would be good to explain in simple terms how it works so others can learn from my research. I have found some websites that explain the basic principles but nowhere near enough to actually understand it, others that explains things without any basics, making it incomprehensible, and others that go way too deep into the the mathematics behind it.

ECDSA stands for "Elliptic Curve Digital Signature Algorithm", it's used to create a digital signature of data (a file for example) in order to allow you to verify its authenticity without compromising its security. Think of it like a real signature, you can recognize someone's signature, but you can't forge it without others knowing.

The ECDSA algorithm is basically all about mathematics.....
 

Video: Arc System Works Details BlazBlue for PlayStation Vita

136w ago - Today Arc System Works Director Geraint Evans has shared a video detailing everything fans would want to know about BlazBlue for PlayStation Vita!

To quote: With the PS Vita launch just around the corner - we thought we'd take a look at a series that's built a reputation for itself among fighting aficionados over the last couple of years.

Currently readying itself for a spot on the 22 February launch line up, BlazBlue is a fighter that's proven something of a cult hit - a series that's earned high praise from critics for its left-field approach to fighting but is still perceived in some fighting circles as 'the weird other one'.

Getting stuck into a little Street Fighter or a bit of Tekken from time to time is comforting, familiar - you know your way around the character roster, their moves and abilities. You know where you stand - and we understand that.





BlazBlue, seems scary in comparison. For the uninitiated, gameplay footage looks full-on, intense - like the circus has arrived for a gunfight at a firework factory. It's hard to look beyond the relentless visual assault and understand the fighting game that lies beneath.

So for all you BlazBlue beginners out there...
 

BioShock Infinite to Support Move, PS Vita Game in the Works

50°
169w ago - Straight from Irrational Games Creative Director Ken Levine via E3 2011 comes news that BioShock Infinite will support PlayStation Move alongside a PS Vita game in the works.

To quote: Let me dish out some home truths here. The BioShock universe hasn't always treated the PlayStation community super well. The first game came out on PS3 over a year after launch on other platforms. To Sony fans, that probably read as, "Hey, what are we? Chopped liver?"

[Register or Login to view links] came to the press conference to say Sony fans are not chopped liver. How's them for bold words? They're fans who have embraced innovation. Who champion cool, weird stuff like Flower and LittleBigPlanet. Who seek out content from all over the globe.

But I'm also here to back our commitment up with action. Like Move integration. Like a new game set in the BioShock universe on PS Vita. Like a free copy of BioShock 1 with each copy of BioShock Infinite on PS3 to ensure that everyone in the PlayStation world gets a chance to see how the whole BioShock magilla began.





I know I didn't give a ton of details today about the Move stuff and the new game on PS Vita. That's because we're still...
