There’s been great feedback highlihghting that the rule “if a line crosses two points , it will cross a third point” might not be absolute. That’s is true , there’s a few exceptions and today I will try to explain one , what would happen if point P and Q share the same position (x and y wise):https://brainbit.uk/posts/elliptic-curve-crypto-addition/Thu, 29 Jun 2017 10:59:26 +0000https://brainbit.uk/posts/elliptic-curve-crypto-addition/Hello! , this will be the sequel of: Elliptic Curve Crypto , The Basics Today let’s try to tackle operations as in addition and multiplication , keep in mind that these are “invented” operations , the fact that it is called addition it’s a mere coincidence , They should’ve been called something different but such is life. I will split this into a few concepts and then lately write about some of the exceptions.https://brainbit.uk/posts/elliptic-curve-crypto-the-basics/Tue, 27 Jun 2017 07:52:26 +0000https://brainbit.uk/posts/elliptic-curve-crypto-the-basics/Alright! , so we’ve talked about D-H and RSA , and those we’re sort of easy to follow , you didn’t need to know a lot of math to sort of grasp the the idea , I think that would be a fair statement. Well things are a little bit steeper when facing ECC , to say the least , it’s got multiple properties and there’s a lot more math in it .https://brainbit.uk/posts/how-does-rsa-work/Fri, 23 Jun 2017 14:27:27 +0000https://brainbit.uk/posts/how-does-rsa-work/Hey guys , I wanted to write a little bit about RSA cryptosystem . RSA is an asymmetric system , which means that a key pair will be generated (we will see how soon) , a public key and a private key , obviously you keep your private key secure and pass around the public one. The algorithm was published in the 70’s by Ron Rivest, Adi Shamir, and Leonard Adleman, hence RSA , and it sort of implement’s a trapdoor function such as Diffie’s one.https://brainbit.uk/posts/can-you-reverse-diffiehellman/Thu, 22 Jun 2017 14:05:45 +0000https://brainbit.uk/posts/can-you-reverse-diffiehellman/Hi All , so in a previous article i tried to explain how D-H works , and i hope I did a good job of it and hopefully there’s no questions , but how hard would it be for the person eavesdropping to reverse the “secret exponents” and guess the key? Initial communication Remember that image ? let’s recap: Jerry and Simon agreed a prime and a base number , while they were chatting about this there’s a third person “Random” that is listening to everything.
