Improve vro security to free up CPU

Data encryption and decryption requires a large number of complex operations. The software processing code is executed by the CPU. If you use hardware encryption, the CPU does not need to participate, you can release valuable CPU resources for more important transactions.

Network security is enhanced by network devices.

In this issue, we recommend that you use the hardware encryption engine to improve the security of your vro.

Network security is an eternal topic. Whether data is secure and reliable in the network transmission process has become an important topic of Information Development in the new era. After all, the transmitted data often involves key data from R & D, finance, sales, and other departments. Once the data is leaked during network transmission, it will bring huge losses to the enterprise's interests and the consequences will be unimaginable.

There are many links, and "vulnerabilities" cannot be prevented

Data is transmitted over the network from one node to another. There are many links in the middle, such as going through different lines, routers, and switches. In the wide area network, these are locations that are difficult for users to effectively control. Whether the data can be guaranteed to be disclosed during these steps cannot be known by network users, all users know is whether the transmission line is smooth, whether there is data packet loss, and whether there is network latency.

To ensure data security, some key industries and large enterprises adopt leased line access. For example, in the financial industry, leased line access is widely used, but leased line access also has the problem of line data being eavesdropped. Because the leased lines provided by telecom operators access FR, DDN, E1, ISDN, X.25, etc.) from the bank's outlets to the sub-branch usually have two copper lines, the data of such copper lines is easy to be intercepted, at the same time, the ISP can also easily perform bypass monitoring on data. Therefore, the leased line is not safe.

Encryption and decryption without CPU involvement

In this environment, how can we ensure the security of users' key data during network transmission?

The best way is to Encrypt Key data. In this way, even if the encrypted data is stolen during network transmission, it cannot be restored to plain text, that is, it cannot be interpreted, fully ensuring data security.

Currently, two encryption methods are generally used: "Software Encryption" and "Hardware Encryption ". However, which of the two encryption technologies is more suitable for enterprise networks? This is also the focus of the battle between "Software Encryption" and "Hardware Encryption.

The data encryption and decryption process requires a large number of complex computing processes. The software method is used, and the CPU executes the relevant software processing code. In hardware mode, the CPU does not need to participate in the data encryption and decryption process. The CPU only needs to send the data to be encrypted to the hardware encryption engine and then encrypt the data to the CPU to complete the encryption process. The same principle applies to data decryption. The data to be decrypted is simply sent to the hardware encryption engine. The encryption engine decrypts the data and sends it back to the CPU, which completes the data decryption process.

Built-in encryption engine, exhausting CPU

With the development of information technology, the amount of data transmitted over the network is increasing. If Software Encryption is adopted, almost all things the CPU does are encrypted and decrypted, the CPU does not care about other key transactions. It wastes valuable CPU resources and seriously reduces network performance. With hardware encryption, the CPU does not need to be involved, releasing valuable CPU resources for more important transactions.

At present, although there are many vrouters with high-performance security functions, it is rare to use the built-in hardware encryption engine in the vro. Ruijie network recently launched the RG-R1762/RG-R2632/RG-R2692 series router, can be said to be second to none.

RG-R1762/RG-R2632/RG-R2692 series router is the biggest characteristic, on the basis of the realization of many security characteristics, is currently in the same grade router, the first to adopt the built-in hardware encryption engine technology, at the same time, the speed is 3 ~ faster than that of Software encryption ~ 10 times, significantly improving the overall performance of the network.
