// FHE Key Generation → IO Evaluation Circuit

/**
 * Abstract: Privacy-Preserving Key-Value Operations
 * 
 * This module demonstrates a hybrid approach combining:
 * - Fully Homomorphic Encryption (FHE) for key generation
 * - Indistinguishability Obfuscation (iO) for evaluation
 * 
 * Theoretical Foundation:
 * We construct an encrypted key-value store where operations
 * are performed on ciphertexts without decryption, followed
 * by iO-sealed evaluation circuits for secure computation.
