Thanks for your querry. I actually meant writing the positive integer n as n=\sum a_{i}^{2} with finite number of terms. But I think this may generalize to...
hi, Let == indicate congruent to. let !== indicate incongruent to. Algorithms such as quadratic seive finds two integers x and y,such that x^2==y^2(mod n) and ...
hai i think there is book for implenting elliptic curves i think book name is implementing elliptic curve by rosing i think its correct i will confirm and let...
Hello frenz Many of us might not have much insight into what is elliptic curve cryptography. I have read a little on the same but the concept is not so clear...
hi, Thats right, you can find more info on this book at the url below. http://www.manning.com/books/rosing Nice book for coding up ECC applications in C. The...
Dear Indocrypt members Given two elements a, b in a finite field K, what is the criterion for deciding whether there exists r such that b=a^r? Can this be done...
Hello, As far as I know there is no way, unless you know 'a' is a primitive element. If there is a way for finding membership in a subgroup, the discrete log...
... Yes, the case where $a$ is a generator makes everything trivial. ... This is a decision problem and I feel this problem cannot be of any help to discrete...
Hello, ... If we choose the polynomial f(x) to be irreducible but not primitive,the element 'alpha' which is a root of f(x) in the extension field will not be...
Thanks Sarad and Sudarshan. This is indeed a decision problem (DP) and does not explicitly ask for the DL (discrete log in the subgroup). Depending on the...
Hello, ... You appear to assume that b belongs to <a> from the second line of your statement. That is what we need to prove. You are also assuming that the...

Dear All I have some querries on Elliptic Curve Cryptography. Can you help? 1. Why are elliptic curves over rationals E(Q) not used in cryptography? These...
perhaps this is due to the limiatations of representing rational points on an elliptic curve in a finite number of bits.. is there a theorem that proves that...
dear sir, the link that u sent for hashclash is bad. Kindly plz check it and let the group know. Thank you very much Murtaza Masalawala Indian Institute of...
Hi, 1. I'm Ashish Sharma of Army Institute of Technology, Pune, India 2. My paper titled "FastFlex: A New Fast and Flexible Cryptographic Function" has been...
Hi there. I saw ur website. Seems to be some good work. If ur looking out for software companies in Pune dealing in security, the Kodito Security Systems is...
Well, Both Salsa and my function are based on Add-Rotate-Xor structure which has found some mention in literature. And Salsa 20 is not faster. For 20 rounds,...
