PROTO-142：简易符号提示界面同态检索降维匹配锁
标准名称：基于子空间正交投影与门限 LWE 的简易符号提示界面同态检索降维匹配锁
技术领域：全同态检索 / 符号语义对齐 / 密文域匹配
Python
import numpy as np
class HCOS_HomomorphicPromptMatcher:
def __init__(self, reduced_dim=16, modulus_q=8380417):
self.d = reduced_dim
self.q = modulus_q
self.theta_match = 12500 # 同态匹配硬红线阈值
def evaluate_encrypted_distance(self, cipher_u_b, cipher_target_b):
# 直接在全全盲密文域执行单步同态差分平方累加
# 模拟同态减法与平方算子
cipher_diff = (cipher_u_b - cipher_target_b) % self.q
homomorphic_dist_sq = np.sum(cipher_diff ** 2) % self.q
