Cryptographic secret
WebIn the special case of a password, the authenticator is the secret. Cryptographic key [ edit] A cryptographic authenticator is one that uses a cryptographic key. Depending on the key material, a cryptographic authenticator may use symmetric-key … Cryptography is widely used on the internet to help protect user-data and prevent eavesdropping. To ensure secrecy during transmission, many systems use private key cryptography to protect transmitted information. With public-key systems, one can maintain secrecy without a master key or a large number of keys. But, some algorithms like Bitlocker and Veracrypt are generally not private-public key cryptography. For example, Veracrypt uses a password hash to generate the si…

WebThe widely accepted notion that the security of the system should depend on the key alone has been explicitly formulated by Auguste Kerckhoffs (in the 1880s) and Claude Shannon (in the 1940s); the statements are known as Kerckhoffs' principle and … Since the key protects the confidentiality and integrity of the system, it is important to be kept secret from unauthorized parties. With public key cryptography, only the private key must be kept secret, but with symmetric cryptography, it is important to maintain the confidentiality of the key. Kerckhoff's principle states that the entire security of the cryptographic system relies on the secrecy of the key.

WebJun 11, 2015 · Ultimately, modern cryptography is based on Kerckhoffs's principle which states that: A cryptosystem should be secure even if everything about the system, except the key, is public knowledge. This is because with the knowledge that we have, this is really the only reasonable way to approach serious, secure cryptosystem design. Share
