verkkosalaus

Verkkosalaus, also known as network encryption, refers to the process of protecting data transmitted over a computer network. This is achieved by using cryptographic algorithms to scramble the data in such a way that it becomes unreadable to unauthorized parties. Only those with the correct decryption key can restore the data to its original, readable form.

The primary goal of verkkosalaus is to ensure confidentiality, integrity, and authenticity of network communications. Confidentiality prevents eavesdroppers from accessing sensitive information. Integrity ensures that the data has not been altered or tampered with during transmission. Authenticity verifies that the sender of the data is who they claim to be.

Common protocols that implement verkkosalaus include Transport Layer Security (TLS), which is widely used for securing web traffic (HTTPS), and Virtual Private Network (VPN) protocols like IPsec and OpenVPN, which create encrypted tunnels for private communication over public networks. Secure Shell (SSH) is another example, used for secure remote login and file transfers.

The implementation of verkkosalaus typically involves a handshake process where the sender and receiver agree on the encryption algorithms and exchange cryptographic keys. These keys can be symmetric, where the same key is used for both encryption and decryption, or asymmetric, which uses a pair of keys: a public key for encryption and a private key for decryption.

Verkkosalaus is crucial for protecting sensitive information such as financial data, personal identification details, and confidential business communications. Its widespread adoption is a cornerstone of modern cybersecurity, enabling secure and trustworthy interactions across the internet and other networks.
