WebThe type of secret is an important characteristic of the authenticator. There are three basic types of authenticator secret: a memorized secret and two types of cryptographic keys, either a symmetric key or a private key. Memorized secret. A memorized secret is intended to be memorized by the user. WebBoth parties must use the same cryptographic algorithm. The cryptographic key that the sending party uses to encipher the data must be available to the receiving party to decipher the data. Figure 1 is a simplified illustration of the cryptographic components that are needed to encipher and decipher data in a secret key cryptographic system. In ...

Why do we keep our keys secret, rather than our algorithms?

WebJun 11, 2015 · Why is it that the common trend in cryptography is to keep the security key a secret but allow the encryption and decryption algorithms to be public. What if both the encryption and decryption algorithms were the secret? In that case there would be no need for a key anymore and it would simplify things a great deal.
