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

Flaws in the symmetric cryptography system: Key allocation problem: the communication between two parties to encrypt communication, the need to negotiate the encryption key through a secret secure channel, and this secure channel may be difficult to achieve key management problems: In a network with multiple users, any two users need to have a shared key, when the network of users n is very large, the number of keys to manage is very large , there is

As a Java programmer, the most painful thing is to choose too wide, can read too many books, often easily confused. I would like to choose some of the technical books I have read, according to the Order of study, recommend to everyone, especially those who want to constantly improve their technical level of Java programmers.

[From Renren network source address: http://blog.renren.com/GetEntry.do? Id = 896285182 owner = 274281790,Very touched !!] In the past, I would like to read a book before reading, but in actual reading, I often "want to read a book" rather than "want to read a book ". This kind of thinking often makes my life very painful. When you want to finish something quickly, your mind is no longer in this matter. This problem has plagued me for a long time in college. I don't realize that this is actuall

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
