"Cryptanalysis refers to the process of analyzing information systems in order to understand hidden aspects of the systems."
The study of cryptographic techniques with the intention of weakening or breaking them.
Encryption and Decryption: The process of converting plain text into cipher text and vice versa.
Cryptography schemes: Different types of cryptographic schemes like symmetric cryptography, asymmetric cryptography, and hashing.
Cryptographic primitives: Fundamental tools that make up a cryptographic scheme such as block cipher, stream cipher, message authentication code (MAC), digital signature, and hash function.
Cryptographic protocols: Sets of rules used to facilitate secure communication between two parties.
Attacks: Various attacks that can be used to compromise the security of a cryptographic system like brute force attacks, dictionary attacks, chosen plaintext attacks, chosen ciphertext attacks, and side-channel attacks.
Cryptanalysis methods: Different methods used to analyze and break the cryptographic system such as frequency analysis, differential cryptanalysis, linear cryptanalysis, and algebraic attacks.
Steganography: The art and science of concealing messages within other messages.
Key management: The process of securely storing, generating, and distributing cryptographic keys.
Public key infrastructure (PKI): A system used to manage public keys and digital certificates.
Digital signatures: A method of verifying the authenticity of digital content and verifying that it has not been tampered with.
Primitives for secure multi-party computation: Methods of computing securely without revealing any confidential information to the other parties involved.
Quantum cryptography: A method of securing communication using quantum mechanics.
Block cipher_modes of operation: Different modes of operation for block ciphers such as ECB, CBC, CFB, and OFB modes.
Side-channel attacks: Attacks that exploit flaws in the physical implementation of cryptographic devices or systems.
Cryptanalysis of symmetric cryptography: Methods used to analyze and break symmetric cryptographic systems.
Cryptanalysis of asymmetric cryptography: Methods used to analyze and break asymmetric cryptographic systems.
Cryptography standards: Standards set by organizations such as National Institute of Standards and Technology (NIST) and International Organization for Standardization (ISO) to ensure security in cryptographic systems.
Cryptanalysis tools: Various tools used for cryptanalysis such as Python Cryptography Toolkit, Cryptool, and OpenCrypt.
Cryptographic libraries: Libraries with pre-built functions and algorithms for cryptographic systems like OpenSSL and Crypto++.
Cryptography in practice: The practical application of cryptography in real-world scenarios such as secure communication, data protection, and financial transactions.
Frequency analysis: This type of cryptanalysis involves analyzing the frequency of letters, numbers, or symbols in a cipher text to uncover the underlying pattern.
Brute force attack: In this method, every possible combination of keys is tried until the correct one is found.
Statistical analysis: This cryptanalysis technique involves a statistical analysis of a cipher text using probability theory, frequency analysis, and other mathematical methods to crack the code.
Dictionary attack: A dictionary attack involves trying every word in a dictionary as a potential key to decrypt the cipher text.
Rainbow tables: These pre-computed tables are used to crack passwords by matching the hash values of the passwords.
Man-in-the-middle attack: A man-in-the-middle attack involves planting an intermediary between two parties communicating and eavesdropping on the communication.
Side-channel attacks: These attacks involve analyzing the physical properties of a system or device, such as power consumption or electromagnetic emissions, to determine the encryption key being used.
Timing attacks: Timing attacks are a type of side-channel attack that involves analyzing the time it takes for an encryption algorithm to process different inputs to determine the encryption key.
Differential cryptanalysis: This form of cryptanalysis involves analyzing differences in cipher texts to uncover any irregularities in the encryption key.
Linear cryptanalysis: Linear cryptanalysis is a method of cryptanalysis that analyzes the linear equations that govern an encryption algorithm to find weakness in the encryption key.
"Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown."
"Cryptanalysis (from the Greek kryptós, 'hidden', and analýein, 'to analyze')"
"Cryptanalysis includes the study of side-channel attacks that do not target weaknesses in the cryptographic algorithms themselves, but instead exploit weaknesses in their implementation."
"The methods and techniques of cryptanalysis have changed drastically through the history of cryptography, adapting to increasing cryptographic complexity."
