A novel scheme based on traditional electronic codebook (ECB) mode was proposed to improve the capability of block-cipher mode of operation.

为提高分组密码工作模式的性能，提出了1个基于电码本(ecb)模式的新方案。

We show that when the attacker has access to an electronic codebook(ECB)oracle, the plaintext cipher block chaining mode(PCBC) can be easily attacked;

对分组密码的工作模式进行了攻击，结果表明如果攻击者能询问电码本（ECB）问答器，则很容易攻破明密文分组连接模式（PCBC）；
