摘要

aaaa密码系统是一种设计良好的加密方案，用于保护可能传输比其密钥大小大的数据集的消息(或明文)。然而，传输大于指定条件的数据并不是一个好主意。这项工作将解释为什么会这样。因此，我们证明了一些最重要的数据位是可以恢复的。尽管完整的参数不可能完全恢复，无论如何，通过泄漏其最重要的位，即使是非常少的量也可能导致任何密码系统不安全。

(In)Security of the AAβ Cryptosystem for Transmitting Large Data

The AAβ cryptosystem is a well-designed encryption scheme for securing a message (or plaintext) which could transmit large dataset than its key size. Nevertheless, the idea to transmit data larger than the specified condition is not a good idea. This work will explain why it is the case. As a result, we show that some most significant bit of the data can be recovered. In spite the very fact that the complete parameter cannot be recovered fully, anyway by leaks of its most significant bits, even of a very little amount could lead any cryptosystem insecure.
