Cryptography plays a vital role in network security by protecting data from unauthorized access, tampering, and eavesdropping. Here's how cryptography contributes to network security: Key Aspects of Cryptography in Network Security 1. *Data encryption*: Encrypting data in transit (e.g., HTTPS, VPNs) and at rest (e.g., encrypted storage) to protect against interception and unauthorized access. 2. *Secure communication protocols*: Implementing secure communication protocols like SSL/TLS, IPsec, and SSH to encrypt data in transit. 3. *Authentication and integrity*: Using digital signatures and message authentication codes (MACs) to verify the authenticity and integrity of data. 4. *Key management*: Managing cryptographic keys securely to prevent unauthorized access and ensure the integrity of encrypted data. Benefits of Cryptography in Network Security 1. *Confidentiality*: Protecting sensitive data from unauthorized access. 2. *Integrity*: Ensuring data is not tampered with or altere...
