Why do ZK proofs need specialized symmetric ciphers?
Traditional ciphers incur many R1CS constraints, raising prover cost. Arithmetization-oriented ciphers reduce these constraints.
answer
intermediate
How does Lumora reduce proving overhead?
It uses Even-Mansour to avoid key schedule circuits and optimizes the number of nonlinear multiplication constraints.

How do multiple instances affect application choices?
Different n values offer trade-offs between security and efficiency, letting users pick parameters like n=64 for high-security cases.
