Cryptography and Cryptanalysis | Cryptography and System Security (Reshoot)

In this comprehensive lecture, we delve into the fascinating worlds of cryptography and cryptanalysis, exploring the art and science of secure communication and codebreaking. Embark on a journey to understand the fundamental principles of cryptography, the techniques used to protect sensitive information, and the methods employed by cryptanalysts to break these codes. Cryptography: The Science of Secure Communication Cryptography is the study and practice of secure communication. It encompasses techniques and algorithms that transform plaintext (unreadable) data into ciphertext (encrypted) data, rendering it unintelligible to unauthorized parties. This process of encryption ensures the confidentiality, integrity, and authenticity of information. Key Concepts in Cryptography: Confidentiality: Protecting data from unauthorized disclosure. Integrity: Preserving the accuracy and completeness of data. Authenticity: Ensuring that data originates from a trusted source. Encryption: Transforming plaintext into ciphertext using a secret key. Decryption: Reversing the encryption process to recover plaintext from ciphertext. Cryptography Algorithms: Mathematical formulas used to encrypt and decrypt data. 👉 Download Ekeeda Application & Learn from the best professors with 10+ years of experience.
