Kodeerimisprotokollid

Kodeerimisprotokollid are a set of rules and procedures used in data transmission to ensure the confidentiality, integrity, and authenticity of information. These protocols are essential in securing communication over networks, especially in the context of the internet. They work by encrypting data before it is sent and decrypting it upon receipt, making it unreadable to unauthorized parties.

One of the most widely used encryption protocols is Transport Layer Security (TLS), which is the successor to the Secure Sockets Layer (SSL). TLS ensures that data transmitted between a client and a server remains private and secure. It uses cryptographic algorithms to encrypt data and verify the identity of the communicating parties.

Another important protocol is Internet Protocol Security (IPsec), which provides secure communication at the network layer. IPsec is commonly used in virtual private networks (VPNs) to create secure tunnels for data transmission. It offers two main modes: Transport Mode, which encrypts only the payload of the IP packet, and Tunnel Mode, which encrypts the entire IP packet, including the header.

Kodeerimisprotokollid are crucial for protecting sensitive information in various applications, including online banking, e-commerce, and secure communications. They help prevent eavesdropping, data tampering, and man-in-the-middle attacks, thereby enhancing the overall security of digital transactions and communications.
