# Term for non-ARX symmetric-key cryptographic primitive design strategy

What's the term for describing designing symmetric-key cryptography primitive out of bitwise operations and shifts and rotations?

The closest thing I've found is this Keccek team's page calling it NORX, but the linked reference says NORX is actually an AEAD algorithm.

• NORX is just a name, not a type of cipher. NORX is actually classified as a duplex sponge based AEAD symmetric cryptographic primitive Jun 27 '19 at 0:10

Bitwise and, or, not, xor are element-wise $$\mathbb{F}_2$$ additions and subtractions; $$n$$-bit shift are based on multiplication by $$x^n$$ reducing $$x^w$$ where $$w$$ is the width of the word; rotation are based on multiplication reducing $$x^w+1$$.
