Q: dimension of Goppa codes

yoyoFor the McEliece/Niederreiter cryptosystems, an efficient seemingly secure choice of code is an irreducible binary Goppa code, defined by an irreducible $g(x)\in GF(2^m)[x]$ of degree $t$ and a support vector $L=(\alpha_0,\ldots,\alpha_{n-1})$ with distinct $\alpha_i\in GF(2^m)$. The code itself ...

Q: Why is SHA3 more secure than SHA2?

Arturo RomanWhy are SHA3 algorithms considered more secure than their SHA2 counterparts? Surely in part, it is due to their resistance to length extension attacks. But specifically, when considering collision resistance they have the same O(n) attack times. Is it because they are more resistant to preimage a...
