从加密值+明文中找出AES密钥 [英] Find out the AES key from encrypted value + plaintext

问题描述

我有两张 AES 加密的票证(见下文)和明文.我可以从这些信息中找到 AES 密钥吗?

I have two AES-enrypted tickets (see below) and the plaintexts to it. Can I find the AES key from this information?

加密类型:带有 PKCS#5 填充的 AES CBC 加密

encryption type: AES CBC encryption with PKCS#5 padding

推荐答案

当一个人可以访问一个或多个明文及其相关密文时确定加密密钥的能力被描述为已知明文攻击"，其中(根据维基百科)AES(目前)不存在漏洞.

The ability to determine the encryption key when one has access to one or more plaintexts and their associated ciphertexts is described as a "known-plaintext attack", to which (according to Wikipedia) AES is not (currently) known to be vulnerable.
