In symmetric key cryptography, both parties must possess a secret key which they must exchange prior to using any encryption. Distribution of secret keys has been problematic until recently, because it involved face-to-face meeting, use of a trusted courier, or sending the key through an existing encryption channel. The first two are often impractical and always unsafe, while the third depends on the security of a previous key exchange. WebOct 23, 2013 · Secure key distribution is another problem. The security of the system is broken if a man-in-the-middle can grab the key while it is being transmitted from Alice to Bob. Asymmetric encryption. Two keys are used in asymmetric cipher (e.g., RSA)—a public and a private one. The public one is available for everyone, but the private one is known ...
WebThe biggest problem with symmetric cryptography is key distribution: ensuring that both sides get the key in a way that no eavesdropper can observe it. For instance, you cannot just send it as a network message containing the key. There are several techniques to handle the problem of key distribution. Manually, by using pre-shared keys (PSK ...
