Difference TLS Vs DTLS protocol

Today in our article we will talk about the difference between TLS vs DTLS protocol. Lets start with the TLS protocol first and then will discuss about DTLS after that.

TLS Protocol
The TCP/IP transport protocols are given an additional layer of security by the Transport Layer Security (TLS) protocol. TLS adds extra security features, like authentication and message tampering detection, and securely sends private data using both symmetric encryption and public key encryption.

TLS lengthens the number of steps required to send data over TCP/IP, which adds to the latency of online communications. However, the security advantages frequently outweigh the additional latency.

TLS encryption is a common practice for most websites and helps shield web applications from data manipulation and eavesdropping. In response to the growing number of security threats and the requirement for encryption on both the client and server ends, the SSL/TLS protocols were created.

TLS is in place to aid in preserving user security and privacy. Without TLS, sensitive data being transferred online, such as credit card numbers, personal information, and login credentials, is susceptible to theft. Unknown third parties could also keep an eye on your emails, web usage, and direct message correspondence.

DTLS Protocol
Data transferred over datagram protocols are encrypted using the secure data transfer protocol DTLS (typically UDP). For datagram protocols, the DTLS protocol offers communications privacy. It offers equivalent security guarantees and is based on the Transport Layer Security (TLS) protocol.

The SSL/TLS protocol is intended to operate over a dependable transport channel (typically TCP). Data loss and records that are out of order are incompatible with SSL/TLS. A data record that enters out of order may not be correctly decrypted and instead contain a MAC verification error.

The TLS is a component of TCP and can guarantee the security of data transmission over TCP. An addition to TLS called Datagram TLS (DTLS) provides data transmission security over UDP.
