但还是遗留一个问题:在第一步中,Alice如何确认收到的公钥是属于Bob,而不是被Eve截取并串改过的? 在上图中,Eve截获了Bob发给Alice的公钥 $K_{pub}$,并替换成自己的公钥$K_{pubEve}$,发给Alice。 Alice拿到了Eve的公钥$K_{pubEve}$,她并不能验证该公钥的真实性,以为这个公钥就是Bob的。这直接导致Eve窃取...

This works well, and now that Alice and Bob have identical keys Bob can use the same method to securely reply. Meeting at a bar to exchange keys is inconvenient, though. It gets even more inconvenient when Alice and Bob are on opposite sides of an ocean. Public-Key Encryption This time,...

Bob is actually having an affair with Alice, and his former partner, upset, cracked the encryption to see what the message contained. Nevertheless, the "gossipy cryptographic protocol specs" all took Alice's side (since the goal of any good crypto system is, of course, tosucceedin this str...

我们这学期上了密码课。马上要考试了。复习的时候突然看到这张ppt。突然觉得自己有密码课还挺幸福的。

(4). 对称加密: 128-bit AES GCM and 256-bit AES GCM. 以上所有的加密算法都与大多数系统兼容,Bob 和 Alice 可以选择一条椭圆曲线来定义他们的密钥对,然后使用给定的哈希算法计算加密密钥,这些通常都是通过 HKDF(HMAC 密钥派生函数)实现的。对于在实际场景中,我们通常使用对称加密,因为这比公钥加密快得多。
Most existing encryption/decryption schemes[3] allow one party to send encrypted data to another with a single shared key. To decrypt, you need that key. In order to get that key, you either need to be one of the two parties (typically referred to as “Alice” and “Bob”), or hope...
