Summary

Iasta is a stream cipher designed for integer-based hybrid homomorphic encryption in IoT systems, using polynomial modular arithmetic over a non-binary plaintext space and rotation-based linear transformations to reduce randomness. A dual S-box design lowers the round count while keeping the same security level. In SEAL library experiments against Pasta, Iasta reports 2x higher client-side throughput at half the storage cost, plus 3-5x higher server-side throughput and 2x faster runtime.
