Steganography explained and how to protect against it

WebA cryptanalyst chooses the plaintext to be encrypted in a chosen plaintext attack; the goal is to derive the key. Encrypting without knowing the key is done via an “encryption oracle,” or a device that encrypts without revealing the key. This may sound far-fetched, but it is quite practical: a VPN concentrator encrypts plaintext to ...
