The Role of Cryptography in Cyber Security

Cryptography plays a foundational role in cyber security by ensuring data confidentiality, integrity, and authenticity in digital communications. It protects sensitive information from unauthorized access through encryption and decryption techniques, making it essential for securing emails, financial transactions, and personal data. As cyber threats grow more complex, modern cryptographic methods like public-key infrastructure (PKI), symmetric encryption, and blockchain-based protocols are becoming critical. Businesses, governments, and individuals rely on cryptography to build secure networks and prevent cyber attacks. Learning cryptographic concepts is now a core focus in professional cyber security training programs offered by institutes like SKILLOGIC, helping professionals stay ahead in the security domain.
