Description: Transport encryption is a security method used to protect the confidentiality and integrity of data transmitted over networks, such as the Internet. This type of encryption ensures that information sent between two points, such as a client and a server, is encrypted, meaning that only authorized parties can access it. Transport encryption is fundamental in modern digital communication, as it helps prevent unauthorized access and interception of sensitive data, such as passwords, financial information, and personal data. The most common technologies implementing transport encryption include SSL (Secure Sockets Layer) and its successor, TLS (Transport Layer Security), which are protocols designed to provide a layer of security in network connections. By using transport encryption, a secure channel is established that protects information during transit, which is essential in applications such as e-commerce, online banking, and private communication. In summary, transport encryption is a crucial tool for ensuring data security in an increasingly interconnected and digitized world.
History: Transport encryption began to gain prominence in the 1990s with the development of SSL by Netscape in 1994, designed to secure communications on the web. Over the years, SSL evolved and was replaced by TLS, which was introduced in 1999. TLS has gone through several versions, continuously improving the security and efficiency of data encryption in transit.
Uses: Transport encryption is primarily used in protecting data in web applications, such as e-commerce, online banking, and the transmission of sensitive information. It is also applied in secure communication protocols and connection between various devices.
Examples: An example of transport encryption is the use of HTTPS, which combines HTTP with TLS to secure communication between browsers and web servers. Another example is the use of VPNs (Virtual Private Networks), which encrypt data traffic between the user and the server.
