As a "lost cause" (because I boycott 3 of the GAFA for personal reasons), I would say that you're very judgemental when saying that, but, as I faced people like the ones you mention in your 1st paragraph, I just used them cards to buy any random item, then get it refunded and cash the money to buy what I really wanted, and where I really wanted. Another lifehack (still questionable though, I agree). I'd like to read what you advice OP in order to ask for cash too :) — OldPadawan 36 secs ago

What is the benefits of quantum computing vs parallel processing using classical computer ?
Can classical parallel processors outperform quantum computing ?

After we've concluded that 64-bit is an insecurity for classical computers, I think many would like to know, how secure in a perspective view, is 64 quantum bits security.
As we know, the Grover's algorithm halves the security strength offered by symmetric key primitives - a 128-bit-key block c...

According to the web page for NewHope, an R-LWE post-quantum key encapsulation mechanism (KEM) candidate for standardization, it comes in types that are or IND-CPA or IND-CCA secure. I know what CPA and CCA security are, but I don't understand the difference between the two types of NewHope and w...

Popular multivariate schemes are constructed by having a several easy-to-invert functions/maps as parivate key, and their composition as the public key.
When signing, the hash, or a padded form of which is converted to a series of multivariate variables, and its pre-image under the maps compute...
I am trying to understand the action of the CSIDH protocol.
Let $E_0:y^2=x^3+ax^2+bx$ be a Montgomery elliptic curve over $\mathbb{F}_p$ for some prime $p$. If we take $\mathcal{O}$ as $End_{\mathbb{F}_p}(E_0)$, then $Cl(\mathcal{O})$ acts on $\mathcal{E}\ell\ell(\mathcal{O})$ as follows:
