: Combine hashing and asymmetric cryptography to provide authenticity and non-repudiation. Applications and Protocols

: Implementation of secure exchange systems using identification and commitment schemes. Future and Advanced Topics Advanced editions of the textbook also cover:

: Uses a single shared secret key for both encryption and decryption. Examples include the Advanced Encryption Standard (AES) and DES . Introduction to Cryptography: Principles and Ap...

: Transform input of any length into a fixed-size "fingerprint" to ensure data integrity without using a key.

: Prevents a sender from denying they sent a message or performed an action, often enforced via digital signatures. Key Cryptographic Techniques : Combine hashing and asymmetric cryptography to provide

The textbook and industry standards divide these techniques into several categories:

: Encrypting data "at rest" on cloud servers or backup drives to prevent unauthorized access if the physical media is compromised. Examples include the Advanced Encryption Standard (AES) and

Practical implementations of these principles are found in various digital systems:
