Cryptography concepts and techniques

  • Cryptography algorithms

    Data Confidentiality, Data Integrity, Authentication and Non-repudiation are core principles of modern-day cryptography.
    Confidentiality refers to certain rules and guidelines usually executed under confidentiality agreements which ensure that the information is restricted to certain people or places..

  • Cryptography algorithms

    Some commonly used asymmetric cryptography techniques are RSA (Rivest Shamir and Adleman), Diffie-Hellman, DSA (Digital Signature Algorithm), ECC (Elliptic curve cryptography).
    Applications of cryptography include ATM cards, computer passwords, and electronic commerce..

  • Discuss various cryptographic techniques to ensure data security

    The five pillars are integrity of data in its original form, availability for authorized parties, identity authenticity, data confidentiality and non-repudiation..

  • What are the 4 principles of cryptography?

    Data Confidentiality, Data Integrity, Authentication and Non-repudiation are core principles of modern-day cryptography.
    Confidentiality refers to certain rules and guidelines usually executed under confidentiality agreements which ensure that the information is restricted to certain people or places..

  • What are the principles of cryptography and techniques?

    Cryptographic principles are the fundamental concepts and techniques that are used in the field of cryptography to secure communication and protect data.
    These principles include confidentiality, integrity, authentication, non-repudiation, and key management..

  • What are the techniques used in cryptography?

    It protects information and communications through codes so only those for whom the information is intended can read and process it.
    There are three main types of cryptography: symmetric key encryption, asymmetric key encryption, and public-key encryption.Jan 6, 2023.

  • What is the basic concept of cryptography?

    Cryptography is the process of hiding or coding information so that only the person a message was intended for can read it.
    The art of cryptography has been used to code messages for thousands of years and continues to be used in bank cards, computer passwords, and ecommerce..

Cryptographic techniques are used to ensure secrecy and integrity of data in the presence of an adversary. Based on the security needs and the threats involved, various cryptographic methods such as symmetric key cryptography or public key cryptography can be used during transportation and storage of the data.

Cryptographic technique

Chaffing and winnowing is a cryptographic technique to achieve confidentiality without using encryption when sending data over an insecure channel.
The name is derived from agriculture: after grain has been harvested and threshed, it remains mixed together with inedible fibrous chaff.
The chaff and grain are then separated by winnowing, and the chaff is discarded.
The cryptographic technique was conceived by Ron Rivest and published in an on-line article on 18 March 1998.
Although it bears similarities to both traditional encryption and steganography, it cannot be classified under either category.

Cryptographic secret, more secure than a salt

In cryptography, a pepper is a secret added to an input such as a password during hashing with a cryptographic hash function.
This value differs from a salt in that it is not stored alongside a password hash, but rather the pepper is kept separate in some other medium, such as a Hardware Security Module.
Note that the National Institute of Standards and Technology refers to this value as a secret key rather than a pepper.
A pepper is similar in concept to a salt or an encryption key.
It is like a salt in that it is a randomized value that is added to a password hash, and it is similar to an encryption key in that it should be kept secret.
