What is the encryption of the link?

Link encryption is a security method used in communication networks for transferring encrypted data between computers. Thanks to this method, the data is encrypted and decrypted with each piece of hardware along the path, such as network routers or other specialized devices. When the communication connection is encrypted in this way, the entire data transfer is hidden in contrast to other encryption schemes where the transfer can still be captured. The method can also be referred to as the encryption of the connection level or encryption of the link layer. This is because everything happens in the bottom layer of the Open Systems InterConnect (OSI), known as a layer of data connection.

because the data packets leave the network interface, the entire packet, clusters of data sent via a network connection, is encrypted. The encryption of the link is this unique, because the information about the header that contains information about the original and target addresses is encrypted together with the SPEsible payload of the data. Secured packets are then sentThrough the line, until they are sitting with another device along the road, at this point the header is decrypted and checked to see if the address information. If the packets did not reach the destination, they are encrypted and sent on the road.

It is useful to maintain safe transmission against someone trying to eaves on line or capture packets for analysis. The attacker is unable to know who the data comes from, where he is heading, and the way he has taken on the way. The process is also usually without a human error, because it all happens automatically, which saves the user from remembering to encrypt its communication, allowing light, regular regular data transfers that must be secure.

There are several shortcomings to access. Encryption of connection is very suffering from public networks such as Jeinternet. Many people who use this method use it only on reserved,Rent lines where greater control over hardware along the road can be achieved. This also means that the keys used for encryption and decryption data must be maintained on multiple devices, so each point along the path potentially vulnerable if the attacker gets access to one of the devices along the route.

Another solution is the method known as SuperCryption, which is used to encrypt the user in the application layer in the application layer, and then the remaining information about the header is encrypted as it goes to a larger network. Another method in super -nception is known as End-to-End encryption. Thus, the primary difference between the encryption of the connection is that the end-to-end method allows the data to go through an unsecured network for a certain period of time, because the keys for encryption and decryption are known at each end of the transfer. Addressing and routing information is still visible for eavesdropping, but the primary payload of data remains safe. In the case of Superencryption, however, where EN is usedD-to-end and interconnecting encryption must rarely go further than the local router before entering the encrypted connection for transport.
