They have decided to use cryptography to achieve this but can't decide on which model. WebThe term “cryptosystem” is shorthand for “cryptographic system” and refers to a computer system that employs cryptography, a method of protecting information and communications through the use of codes so that only those for whom the information is intended can read and process it.
WebMar 8, 2024 · In simple terms, “cryptography” refers to the art of securing sensitive information using mathematical algorithms. These algorithms stop third parties, commonly known as adversaries or hackers, to peep into your data.
Cryptographic hash functions are cryptographic algorithms that generate and use keys to encrypt data, and such functions may be viewed as keys themselves. They take a message of any length as input, and output a short, fixed-length hash , which can be used in (for example) a digital signature.
