The research and implementation of chosen ciphertext attacks .

选择密文攻击法之研究与实作。

The type of operations used for transforming plaintext to ciphertext .

明文转换为密文的操作类型。

Without breaking the encryption , a hacker can infer significant information from the context in which the ciphertext is stored .

黑客无需进行解密，即可根据存储密文的上下文推断出重要信息。

This seed is encrypted , and the result is combined with a block of plaintext to produce the ciphertext .

加密种子后，将加密结果与明文块结合产生密文。

As long as the noise does not grow too large , the decryption algorithm can take all the apparent gibberish produced by the operations and recover the bit inside the final ciphertext , which contain the desired result of the processing .

只要噪声不至于过大，加密算法都能识别那些由运算产生的、明显杂乱的信息，并使最终暗文中的比特位复位，这种暗文包含整个流程所期望的结果。
