The paper also tentatively discusses several related encryption algorithms to improve the security and analyzes the plaintext key space, ciphertextkey space and encryption strength.
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。

If the same block is encrypted twice with the same key, the resulting ciphertext blocks are the same.
如果相同的块加密两次使用相同的密钥，由此产生的密文块是相同的。

The public key cryptosystem secure against chosen ciphertext attacks is a very strong secure cryptosystem and is a useful primitive for designing protocols that resisting active adversary.
