相对公钥密码算法，接收方可以在不知道明文的情况下，直接对密文执行融合，节省了因解密带来的能量消耗。
Corresponding to public key cryptographic algorithm, it can save energy consumption because the receiver can aggregate cryptograph directly instead of obtaining explicit terms.
同时对这种加密算法的明文密码空间、密文密码空间和加密强度等作了初步的分析。
Therefore the decryption time and difficulty can be greatly increased, and the cipher can be protected from decryption in this algorithm.
提出两个抗选择密文攻击的门限密码系统。
Two threshold cryptosystems secure against chosen ciphertext attacks are proposed.
