TLS encryption protocol aims primarily to provide security, including privacy, integrity, and authenticity through the use of cryptography, such as the use of certificates, between two or more communicating computer applications.

TLS encryption is a proposed Internet Engineering Task Force standard, first defined in 1999, and the current version is TLS encryption 1.

Since applications can communicate either with or without TLS encryption, it is necessary for the client to request that the server set up a TLS encryption connection.
| FactSnippet No. 1,602,652 |
Once the client and server have agreed to use TLS encryption, they negotiate a stateful connection by using a handshaking procedure.
| FactSnippet No. 1,602,653 |
Attempts have been made to subvert aspects of the communications security that TLS encryption seeks to provide, and the protocol has been revised several times to address these security threats.

The TLS encryption group was made up of individuals from Japan, United Kingdom, and Mauritius via the cyberstorm.

TLS encryption typically relies on a set of trusted third-party certificate authorities to establish the authenticity of certificates.

In July 2013, Google announced that it would no longer use 1024-bit public keys and would switch instead to 2048-bit keys to increase the security of the TLS encryption it provides to its users because the encryption strength is directly related to the key size.

Historically, TLS encryption has been used primarily with reliable transport protocols such as the Transmission Control Protocol.

Primary use of TLS encryption is to secure World Wide Web traffic between a website and a web browser encoded with the HTTP protocol.

TLS encryption can be used for tunnelling an entire network stack to create a VPN, which is the case with OpenVPN and OpenConnect.

TLS encryption is a standard method for protecting Session Initiation Protocol application signaling.
| FactSnippet No. 1,602,661 |
The attack involved tricking servers into negotiating a TLS connection using cryptographically weak 512 bit encryption keys.

At that time, more than 81,000 of the top 1 million most popular websites were among the TLS encryption protected websites that were vulnerable to the DROWN attack.

Sweet32 attack breaks all 64-bit block ciphers used in CBC mode as used in TLS encryption by exploiting a birthday attack and either a man-in-the-middle attack or injection of a malicious JavaScript into a web page.
| FactSnippet No. 1,602,664 |
The attacks worked because the TLS encryption implementation used on the affected servers incorrectly reused random numbers that are intended to be used only once, ensuring that each TLS encryption handshake is unique.
| FactSnippet No. 1,602,665 |
TLS encryption interception is the practice of intercepting an encrypted data stream in order to decrypt it, read and possibly manipulate it, and then re-encrypt it and send the data on its way again.

Such content could otherwise not be detected as long as it is protected by TLS encryption, which is increasingly the case as a result of the routine use of HTTPS and other secure protocols.
| FactSnippet No. 1,602,667 |
TLS encryption provides a secure shortcut in the handshake mechanism to avoid these operations: resumed sessions.
