Q: What do you call a random number that affects the calculation, but not the result?

Pierre AbbatThis is about the same random ladder algorithm as my previous question. It computes f(g,n,r)=n*g or g^n (depending on the group notation), where g is a generator of a group. Suppose n=5882353. This can be calculated as ((((((((((1*2*2+1)*2+1)*2*2*2+1)*2+1)*2+1)*2*2*2*2*2*2+1)*2+1)*2+1)*2+1)*2+1)*...

If I'm designing a CSPRNG in hardware based on ChaCha8, is there any reason not to simplify the final XOR of the permutation output with the input block by only XORing the key? The nonce, counter, and constant are public, so XORing them with the permutation output feels a bit wasteful.

Q: Masters Thesis ideas

cools_Not_coolI will begin studying at Kings college studying advanced Cyber Security, I have a passion for cryptography I can particularly express what, I just have found this topic so interesting for many years now, I have worked in research which was integrating the algorithms (PQ round 3) into OpenSSL and ...
