Cryptography Basics
This test evaluates the understanding of fundamental cryptographic concepts and techniques.
Skill Required
Encryption Algorithms
Understanding and applying various encryption algorithms (e.g., AES, RSA) to protect sensitive data.
Hashing and Integrity Checks
Knowledge of hashing techniques (e.g., SHA-256) to ensure data integrity and prevent tampering.
Key Management
Expertise in secure generation, storage, and exchange of cryptographic keys for protecting information.
Test Structure
Section 1
This domain explores the principles and applications of symmetric cryptography, where the same key is used for both encryption and decryption. It covers foundational concepts, cryptographic algorithms such as AES and DES, key management, and the strengths and limitations of symmetric encryption. Emphasis is placed on its role in ensuring confidentiality, data integrity, and secure communication in various systems.
Section 2
This domain focuses on the principles and mechanisms of asymmetric cryptography, where a pair of keys—public and private—is used for secure communication. Topics include key generation, encryption and decryption, digital signatures, and certificate-based authentication. Emphasis is placed on understanding the mathematical foundations and practical applications of algorithms like RSA, ECC, and Diffie-Hellman.
Section 3
This domain explores the concept of hash functions, which are algorithms used to convert input data of arbitrary size into a fixed-size value, known as a hash or digest. It covers the properties of a good hash function, such as determinism, uniqueness, and collision resistance. Topics include cryptographic applications, hash function types (e.g., MD5, SHA-256), and their role in ensuring data integrity, digital signatures, and password storage.
