Suppose you visit a bank website to transfer money, but you login to a fake bank website, after entering the account and password, the server prompts because of internal network error, please try again later. At this time, your real account has been stolen by the illegal people inside the money. This time we need a mechanism to prove the site that we're visiting. H

As you know, the multithreading security of Java is implemented based on the lock mechanism, and the performance of lock is often unsatisfactory.The reason is that Monitorenter and Monitorexit, the two bytecode primitives that control multithreading synchronization, are implemented by the JVM relying on operating system mutexes (mutexes).A mutex is a resource-intensive operation that causes a thread to hang and, in a short time, needs to be re-dispatched back to the original thread.In order to o

In the process of planning and designing a website or software, we often hear this discussion: "This function is designed too much" or "we want to be able to handle it more lightly". It seems that light design is a hot topic today, but also in the ascendant Web2.0 of the designer's favorite (see Those in the world everywhere SNS site, whether visual elements or interactive process can be light light). This paper, from the point of view of practice and summarization, puts forward 6 techniques to

Recently took over a security certification program. It involves a lot of security authentication means, such as dynamic password, CA certificate, Usbkey, fingerprint and so on. This is a simple introduction to the principle of dynamic cryptography. What is a dynamic password card.Dynamic password card is a built-in power supply, password generation chip and display, according to the special algorithm to automatically update the dynamic password ever

A simple database access layer based on EntityFramework Core, applicable to lightweight database services and lightweight Databases The code of this access layer is actually from a senior in the garden. I just thought it was good and recorded it. The access layer needs to install EntityFramework Core through Nuget, but I personally think EF 6 can also be used. It is best to match databases with SQL Server (

string by "/" and into the array $getparam. The reason behind the for loop is starting from 2 is because $getparam[0] represents the controller, $GETParam [1] represents the method. These are not parameters, they are all in the $_get, and they are some parameter information. The following controller name and method name is the first detection of the existence of $getparam, if it exists in the $getparam, if it does not exist then the detection according to the controller nam

first, micro-services will become lightweight Architecture needs to be designed by people, who are called architects. Many people may not have given the architect the title, but they are doing the work of architecture. We believe that the structure of this work will always need to be done by people, may not be in the short term by the machine to replace. If we do not understand what the architecture is, or if we are puzzled by the responsibilities of

made great progress, with the ever-increasing informatization of all military services from military daily to wartime, from the back to the front, from superiors to the grass-roots, and the increasingly electronic and streamlined command functions, currently, the storage of large disk databases cannot fully meet the needs of electronic warfare, unmanned warfare, and lightning warfare for large volumes of data and fast access. A mechanism for fast data access is urgently needed. At the micro lev
