Questions tagged as ['output-size']
Output size refers to the output size of specific cryptographic functions. It is especially relevant when the output must fit into a resource constrained system or protocol. For signatures it is the signature size, for KEM schemes it is the size of the encapsulated key.

What hash based digital signature algorithms exist that have reasonably small signature sizes?
What hash based digital signature algorithms exist that have reasonably small signature sizes?
By reasonably small, I mean not much bigger than what you would get with a 256-bit ECDSA (which I believe has a signature of about 64 bytes). If nothing close exists, then what's the smallest signature size I can get?
I want 128 bit security or better (although its not a hard requirement).
I will be si ...

Size of group elements in a bilinear context
In a asymetric pairing context, which size (in bits) should have the elements of $\mathbb{G}_1,\mathbb{G}_2$ and $\mathbb{G}_T$ if we consider the most efficient elliptic curves?
