How to choose a suitable encryption software

How to choose a suitable encryption software

One: Popular encryption patterns on the market

Transparent encryption : The design idea of transparent encryption is based on Windows file System (filtering)-driven (IFS) technology, which works on the core layer of windows . When we install the computer hardware, we often install its drivers, such as the printer, the drive of theU Drive. File system drivers are a kind of virtual driver that handles files as a device. When an application operates on a suffix file, the file driver monitors the operation of the program and changes how it operates to achieve the encryption effect.

Environment Encryption : The design of environment encryption is the client in the case of a secret, the launch of an encrypted sandbox, sandbox is a container, the secret software, files thrown into the container encryption. The container is transparent and the user does not feel its presence. Using the most advanced disk filter drive, file filtering drive, network filtering drive, such as kernel-level deep encryption anti-leak technology, each module only do what they do best, so very stable. Those who did not enter the Gaza box pattern are separated from the two spaces and are isolated from each other, so there is no need to worry about leaks.

Second: The stability of the product

No stability does not talk about the application, after looking at the domestic brand of a wide range of encryption software, many people are attracted by the peripheral features of cryptographic software and neglect the functionality of the cryptographic software itself. Type selection first ask is not BS architecture Ah, there is no desktop control, can be remote push, can not be compatible with LINUX,MAC and other functions. I think these fancy features can really make the application icing on the cake, but ignoring the core stability of encryption software, talking about functionality is the wrong way to choose encryption software.

No contact with encryption software, relying on the experience of selection management software, it is easy to ignore the stability of encryption software. Feel that software development mature a little, can guarantee stability, encryption software and management software, it involves the WINDOWS underlying driver, not only to achieve encryption protection, but also to ensure that the stability of the system in the development of a very difficult job. Most of the management software is relatively stable, but the encryption software can truly stabilize the product is really not much.

Several manifestations of cryptographic software instability

1 : Destroying Files

The destruction of drawing documents is the first enemy of cryptographic software, often occurring in transparent encryption class software. Transparent encryption software in the course of operation, accidental file damage, resulting in documents can not be seen, this is the most reluctant to happen to customers, but it happened. In the development phase of the encryption software industry, many software has this problem, that is, now, the so-called famous encryption software to destroy the file is not uncommon. Transparent encryption class software will never destroy the file, it is almost impossible. Just in what circumstances to destroy the drawings, the probability of how much. But one thing that destroys files is a headache for businesses, and maybe that file is a department or a project team that spends a week or more on the results, and this problem does not occur in environment encryption.

This problem for the design industry, there are drawing document requirements of the company, need to carefully consider the selection. If a good product is not selected, there is no help for future use, and there are a lot of problems that affect employees ' normal work.

2: frequent conflicts with operating system

Blue screen crashes and other phenomena, which is a typical use of the company's problems. This recurring system conflict makes the user very mad, which directly leads to the customer's idea of abandoning the use of cryptographic software. If the encryption kernel is self-developed, the solution is relatively simple, is the process of patching bugs , software applications more customers,Bugs are resolved more, the system gradually stabilized. If a few simple bugs of encryption software can not be resolved, it is necessary to suspect that it is not self-developed, some manufacturers buy someone else's kernel or OEM other things, do not have the ability to harness the cryptographic core, some small problems, solve very laborious.

The customer uses the encryption software to appear the freezing, the slow speed and so on a series of questions, whether is oneself software problem? Not necessarily! On the one hand, employees emotionally on the encryption software, coupled with small and medium-sized computer maintenance is not standard, a little bit of a problem without analysis attributed to encryption software. So our implementers have spent a lot of time troubleshooting the source of the conflict, or proving their innocence, or identifying the cause of the problem.

How to find a stable encryption software, this is very difficult, first of all to test and trial, testing is just a simple use of software functions, but does not reflect the overall stability of the software. If the condition permits, it is best to install it on your computer for a period of time, so that you can test the basic stability of a cryptographic software. If your own trial can not go on, such a product is necessary to sell it. But to prove whether a product is really stable, or whether it has a large number of applications, this is at least hundreds of customers, the number of sites more than thousands of, to test a product truly stable.

　

III: Compatibility of products

Product stability and compatibility itself is not divided, such as the stability of the system, in fact, with a variety of software compatibility, operating system compatibility. We put it into the software's underlying stability, which is actually compatible. What we say here is more compatible with other management software or hardware applications. This is very important, a very stable encryption software, if not good integration with other systems, the project may eventually be stuck.

1 : ERP,PDM,OA and other management software compatibility integration.

transparent encryption class software : To be able to guarantee the use of encryption environment, ERP exported files automatically encrypted, ERP can read encrypted files, and ensure that the system is normal, it can. The integration of PDM is relatively complex, customer requirements are more, some customers require the entire ciphertext, encryption into the encryption, and the normal built-in browser preview, the PDM system to read properly. While some customers are required to enter PDM , the files are automatically decrypted and the files are automatically encrypted when the PDM system is out. PDM for CS schemas is relatively easy to integrate, and BS is more difficult to do with PDM , and more problems may be encountered. As with BS schema PDM , there are many problems with OA , especially the weboffice issue, and there are still few products that can be followed by the Weboffice Good integration. Because of the limitations of transparent encryption, the integration of management software is less than the environment encryption.

Environment Encryption Software: Environment encryption software and management software integration is better, because the encryption mode is not the same, in the integration with the management software will be more easily recognized by customers, environmental encryption class can be seamless integration with management software. ERP,PDM , including OA and other management software, whether it is CS architecture or BS architecture can be compatible. Can be done only the client pc or trusted pc to access the management software, does not affect the internal browser normal browsing, outgoing files can choose whether encryption. In the aspect of compatible management software, the environment encryption software is still doing better.

2 : Technical drawings, documents and other encryption protection

Since it is necessary to encrypt the drawings, it will inevitably involve the design of customers and manufacturing processing center customers, the most common customers are CNC design, designing institutes, research institutes, advertising companies. Drawing design class is more cumbersome is the NC class need to guide the drawings to the relevant equipment, and then by the equipment processing.

transparent Encryption class software : The better solution is to encrypt the file through the software to the machine, the transmission process of automatic decryption. Because the integration with the machining center is very frequent, and the processing center of the software, so the workload is relatively large, and settings can let users customize, if this can not be customized, it is a headache, once encountered similar customers, it will be very painful.

Environment Encryption Software : The solution to the environment encryption is generally directed to the processing center, because the environment encryption is not for the process control, so not because of the variety of software can not be customized problems, in the paper directed decryption sent to the machining center, You can also do a monitoring backup, because to the monitoring center itself is required clear state, in the sending process for more security, you can do a monitoring backup at a later date these to the processing center of the files to conduct an audit, in order to prevent the random transmission of other critical information.

3 : Encryption protection for source code

For source code encryption, this type is generally a software development company, hardware product development manufacturers, website development,APP development and other components. Customers need to write the chip automatically decrypted, most of the electronic enterprises need to the embedded board or other hardware peripherals for burning debugging. The customer requires that the program source code be encrypted. and is automatically decrypted when the chip is written. This requires both the encryption software to support source code encryption, but also require encryption software to do output automatic decryption (similar to the drawing machining center).

Transparent encryption software : In the process of encrypting with the source code, a lot of processes to call the source code, like the machining center, the need for custom tools, some encryption software needs to use the Task Manager to see what process calls, their own handwritten down, then to do the integration, it is very backward, Some software cannot be customized. This will meet the same problem as the machining center, once there is such a customer, or this demand, will inevitably become a headache. There are some Web site development customers, need to do local debugging, if encrypted after the local debugging will not be able to see the content.

Environment Encryption Software : In the development process, the environment encryption can be based on their own design advantages, in the protection of the source is handy. When the user is debugging, the hardware can be trusted settings, the source code is sent to a specific device, so that users can make debugging calls. If the user does not trust the security of decentralized information, you can set a white list, recording hardware debugging files for later review, tracing the source.

These are some of the key points in the selection of cryptographic software products, which are also the criteria for evaluating the performance of a cryptographic software. You can refer to the above points, to measure the ability of the software, to help enterprises find a suitable for their own encryption software.
