tls definition

What is the industrial Internet of things?In short, it is the specific application of the Internet of things in industrial control.What is SSL/TLS?SSL (secure Sockets layer Secure socket), and its successor Transport Layer Security (Transport layer Security,tls) is a security protocol that provides security and data integrity for network traffic. TLS encrypts the

SSL is the abbreviation for foreign language "secure Sockets layer", which is called "Secure Sockets Layer" in Chinese.It was designed by Netscape in the middle of the 90 century. (Incidentally, Netscape not only invented SSL, but also invented a lot of Web infrastructure-such as "CSS stylesheets" and "JS scripts").Why to invent SSL this protocol pinch? Because the HTTP protocol used on the internet is plaintext, there are a number of drawbacks-such as the fact that the transmitted content is pe

Handshake process of SSL/TLSDuring the handshake process of SSL/TLS, parameters need to be exchanged between the client and the server, as follows: The client provides various cipher suites that it supports (including cryptographic algorithms and hash functions) The server chooses the cipher suite that it also supports and notifies the client that the two will trans

A prefaceThe first thing to clarify is the confusion of names:1 SSL (Secure Socket Layer) is a secure transport protocol designed primarily for the web by Netscape Corporation. This kind of protocol has been widely used on the web.The 2 IETF (www.ietf.org) standardizes SSL, RFC2246, which is called TLS (Transport Layer Security), and technically, the difference between TLS1.0 and SSL3.0 is very small. Since this article does not deal with the small di

SSL (secure Sockets layer), and its successor, TLS (Transport layer Security, Transport layer safety) is a security protocol that provides security and data integrity for network communications. TLS encrypts the network connection with SSL at the transport layer.

Thread Local variable introduction can solve the problem of non-synchronization of static or global variables modified by multiple threads. For a simple example, a function FN may need to modify a static variable. The intention of writing this function is to call the function in its own thread, but if other threads may call this function, the value of this static variable may be damaged. Use local variables of the thread to ensure that each thread uses its own copy and does not interfere with ea

Thread Local Storage (TLS) enables multiple threads of the same process to use an index allocated byTlsallocFunction to store and retrieve a value that is local to the thread. in this example, an index is allocated when the process starts. when each thread starts, it allocates a block of dynamic memory and stores a pointer to this memory in the TLS slot usingTlssetvalueFunction. The commonfunc function uses
