TLS 1.2
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network. The communication protocol, protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible. The TLS protocol aims primarily to provide security, including privacy (confidentiality), integrity, and authenticity through the use of cryptography, such as the use of public key certificate, certificates, between two or more communicating computer applications. It runs in the presentation layer and is itself composed of two layers: the TLS record and the TLS Handshake (computing), handshake protocols. The closely related Datagram Transport Layer Security (DTLS) is a communications protocol providing communications security, security to datagram-based applications. In technical writing you often you will see references to (D)TLS when it applies to both versions. TLS is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cipher Suite
A cipher suite is a set of algorithms that help secure a network connection. Suites typically use Transport Layer Security (TLS) or its now-deprecated predecessor Secure Socket Layer (SSL). The set of algorithms that cipher suites usually contain include: a key exchange algorithm, a bulk encryption algorithm, and a message authentication code (MAC) algorithm. The key exchange algorithm is used to exchange a key between two devices. This key is used to encrypt and decrypt the messages being sent between two machines. The bulk encryption algorithm is used to encrypt the data being sent. The MAC algorithm provides data integrity checks to ensure that the data sent does not change in transit. In addition, cipher suites can include signatures and an authentication algorithm to help authenticate the server and or client. Overall, there are hundreds of different cipher suites that contain different combinations of these algorithms. Some cipher suites offer better security than others ...
