Usually encrypting information is used to defend against network eavesdropping.

What are the ways to defend against network eavesdropping?

Information encryption technology uses mathematical or physical means to protect electronic information during transmission and storage to prevent leakage Technology.

Confidential communication, computer keys, copy-proof floppy disks, etc. all belong to information encryption technology. (Recommended study: web front-end video tutorial)

Encryption in the communication process mainly uses passwords. In digital communication, computers can be used to use encryption methods to change the digital structure of the load information. Computer information protection is mainly based on software encryption.

The most popular encryption systems and encryption algorithms in the world currently include: RSA algorithm and CCEP algorithm. To prevent encryption breaches, encryption software often uses hardware encryption and encrypted floppy disks.

Some software products often come with a small hard card, which is a hardware encryption method. Using a laser to punch holes in the floppy disk can prevent illegal copying by causing unknown local memory corruption in the software's storage area.

Such an encrypted floppy disk can be used by people who do not master encryption technology to protect software. Due to the increasingly serious problems of illegal copying, decryption and piracy of computer software, which have even caused international disputes, the research and development of information encryption technology and encryption methods have attracted the attention of the computer industry in various countries and are developing with each passing day.

Encryption Technology Application

In the conventional postal system, the sender uses an envelope to hide its content. This is the most basic confidentiality technology. In e-commerce, The physical envelope is no longer the representative choice.

In order to achieve the confidentiality of electronic information, it must be achieved that the information is unreadable by anyone except the specific recipient. In order to ensure the information security of trading partners who share design specifications, certain means must be used to hide information, and the most effective means of hiding information is encryption.

Confidential communication, computer keys, copy-proof floppy disks, etc. all belong to information encryption technology. Encryption in the communication process mainly uses passwords. In digital communication, computers can be used to use encryption methods to change the digital structure of the loaded information. Computer information protection is mainly based on software encryption.
