MANTIS

Low-latency tweakable block cipher designed for memory encryption. 64-bit block size with 128-bit keys and 64-bit tweaks using reflection-based structure with 14 rounds. Optimized for minimal latency in hardware implementations. Note: Decryption uses modified key derivation per reflection property.
