Mostly randomly generated noise. A play on the fact that side-channels can be rendered useless by adding random noise. The same is true for chat rooms: they can quickly degenerate to many intertwined completely off-topic "random" discussions. Like in the case of side-channels, there is stil...

The following is a quotation from my cryptography course: Recent results on the discrete logarithm raise big concerns on the security of elliptic curves over a binary field. What are these results? Also, is characteristic three safe?

Till now all we know is Hasse's theorem, which states that $|\#E(p)-(p+1)| \leq 2\sqrt{p}$, where $\#E(p)$ is the total number of points in $E_p(a,b)$. Is there any other theorem which defines relation between points on elliptic curve $E_p(a,b)$ ? I want to find the maximum interval of $x$ co-o...

According to my understanding there are some pretty solid seeming roadblocks to carrying out an index calculus on an elliptic curve over a finite field. The general strategy is to take points over $E(\mathbb{F}_p)$, lift them to points over $E(\mathbb{Q})$, and then hope that the curve over $\mat...

Alice wishes to send Bob a number $n$ between 0 and 255. Bob has a private, public EC key pair $(b, B)$ where $B = bG$ and $G$ is an already agreed upon base point on the ed25519 curve. Alice could roll a random number $r$ and perform a Diffie Hellman exchange to compute the shared secret $rB$....
