I'm sorry to do so , but it's helpless to say sorry. I want a good job , I must support my parents. Figure 7.19 "Glacier" Client Main Interface 3. Analyze the security requirements of computer networks. 3.1.1 Data encryption technology (8) Recipient B verifies the digital signature, and first decrypts the digital signature with the public key of sender A to obtain the digital digest MD . 8.1.2 Security Threats of Web Services (4) The newly purchased computer should be checked for viruses before use to prevent the machine from being infected. (1) Target : Fill in the IP or domain name of the FTP site to be cracked , such as 169.254.43.149 here . Since this type of webpage is an ActiveX webpage file containing harmful code , all ActiveX plug-ins and controls, Java scripts, etc. are prohibited in the IE settings to avoid being shared. The specific method is: execute "tool" in the IE window The RSA asymmetric key cryptosystem is used to transmit the DES key,new ccna 200-301 topics, and the advantages of the two cryptosystems can be integrated, namely Obtain system access rights through counterfeiting, identity attacks, system vulnerabilities, etc., so that illegal users can enter the network system to read, delete, modify, and insert information, etc. The application of quantum technology in cryptography is divided into two categories: one is the use of quantum computers to analyze traditional cryptosystems; the other is the use of single-photon uncertainty principle to achieve key management and information encryption at the fiber level. That is quantum cryptography. Large scale quantum computers is equivalent to a parallel computing system over the traditional sense, in a few seconds using a quantum computer can decompose the bell the RSA 129 public key. According to the development of the Internet, the all-fiber network will be the development direction of network connections in the future. The use of quantum technology can realize the traditional cryptosystem, complete key exchange and information encryption at the fiber level, and its security is based on Heisenberg 's uncertainty In principle, if an attacker attempts to receive and detect the information ( polarization ) of the information sender , it will cause a change in the quantum state. This change is irreversible for the attacker, but can easily Detect whether the information is under attack. At present, quantum encryption technology is still in the research stage ( in a leading position in our country ) , and the effective distance of its quantum key distribution QKD on the optical fiber cannot meet the requirements of long-distance optical fiber communication.
