/**
 * kMOSAIC Parameter Sets
 *
 * Security Analysis:
 * - SLSS: Based on LWE hardness with sparse secrets. Security ≈ n * log2(q) / (2 * sigma²)
 * - TDD: Tensor rank decomposition is NP-hard. Security ≈ n² * log2(r) bits
 * - EGRW: SL(2,Z_p) Cayley graph with 4 generators. Security = k * log2(4) = 2k bits
 *   (k=128 gives 256 bits, k=256 gives 512 bits)
 *
 * Performance Considerations:
 * - SLSS: O(m*n) for encryption, O(n) for decryption
 * - TDD: O(n³) for tensor operations - MOST EXPENSIVE
 * - EGRW: O(k) for path computation - FASTEST
