What is Encryption Software?

Encryption software has developed rapidly. At present, the most common is transparent encryption. Transparent encryption is a technology that automatically encrypts data written to a storage medium at the operating system level according to requirements. Transparent encryption software, as a new method of data confidentiality, has been popular with many software companies, especially manufacturing software companies and traditional security software companies since it went public in 2005. It also brings customers who need to keep sensitive data confidential. Hope. Since the listing of encryption software, the market share has increased year by year. At the same time, after several years of practice, customers have put more demands on software developers. Different from the first one or two years when encryption software products were first launched on the market, different software vendors held their own words. After several trials in the market, customers and manufacturers have a more unified understanding of transparent encryption software.

Encrypting Software

Encryption software is developing rapidly, the most common currently is

Application of database encryption technology

After the data stored in the relational database is encrypted, it is used to encrypt and protect the data in the relational database when the foreground application accesses the ciphertext data in the background database to prevent information from being stolen illegally. It is common in relational databases. Based on the views and triggers, by implementing multi-level views and combining triggers based on row identifiers to automatically encrypt and decrypt sensitive data to achieve the goal of transparency to applications, the application system does not need to be modified; through multi-level views, Precise judgment of database query behaviors, so that you can construct special ciphertext and plaintext data cache strategies based on the LRU cache management mechanism for different types of query behaviors, and construct a batch pre-decryption strategy for ciphertext data to achieve efficient Cipher query.

Database encrypted cipher text indexing technology

After the data stored in the database is encrypted, the original plaintext data index will inevitably fail. In the process of querying the ciphertext data, if you want to mention the query speed, you must first make a ciphertext index to increase the hit rate of the query results. An index creation, retrieval, and maintenance method based on a lightweight ciphertext index structure without a partial order relationship. This structure can represent the node relationships in the index, is easy to maintain, and has low maintenance costs. The data stored in the index is ciphertext. Because there is no partial order relationship between the data, it cannot be analyzed, and the data is guaranteed to be secure. The ciphertext index retrieval method based on this unordered relationship can quickly retrieve and locate the ciphertext data; the maintenance method can effectively maintain the index data and node relationships, and ensure the correctness of the index data in the concurrent operating environment Sex.

Automatic backup of cipher text becomes a must-have feature

Data storage is a complex process.

Encryption software can be divided into passive encryption and active encryption according to the implementation method.

The encryption software for enterprises on the market is mainly divided into two types: the offline version and the network version. The main difference is that the offline version does not require LAN support and can be installed separately.
The offline version of the encrypted program is controlled. Any changes need to be repackaged by the software vendor. And each computer needs to extract the hardware code and register and install it separately.
The network version of the encryption program and all configuration can be completed through the server, and no need to re-register when changing computers. ^[3]

Rich encryption software product line

Customer demand is always the compass for product development, and the transparent encryption software market is no exception. At the beginning of the emergence of the transparent encryption software market, all manufacturers adopted the same publicity model. What's more, some manufacturers directly copied the publicity materials of other peers. It now appears that everyone was introducing the benefits of transparent encryption at that time, and did not reflect the advantages of their own products. Of course, the main reason was that manufacturers did not understand the market demand for encryption software at that time. With more than two years of face-to-face communication and collisions with customers, manufacturers of transparent encryption software products have a deeper understanding of the market and new trends in product positioning and development.

Transparent encryption technology just emerged

When the transparent encryption technology first appeared, the main selling point was compulsory encryption. It can also be said that compulsory encryption has become synonymous with transparent encryption. All vendors, regardless of whether it is a network version or a discretely licensed version, are directed towards mandatory encryption. Therefore, the product has only one type of forced encryption of the sensitive files generated by the specified application, and the expected customers are basically single LAN users. In fact, on the one hand, customers not only worry about the leakage of files from the inside, but also have to consider the leakage of files from the outside; on the other hand, not only group customers have confidentiality requirements, but also general personal PC users have a large number of file encryption requirements. Therefore, more transparent encryption products have emerged as the times require.

For some companies, their partners can also access their sensitive documents. Therefore, companies need to control sensitive documents issued to external parties such as suppliers. In response to such customer needs, some manufacturers have developed outbound document control versions that control the aging of outbound documents, print permissions, and the number of openings. Some also call anti-diffusion software.

Users need confidentiality

The need for file confidentiality is not only in the enterprise, but also necessary for individuals. Kings and masters of file and folder encryption circulating on the Internet are good evidence. Transparent encryption is very suitable for making an enterprise version of forced encryption, but transparent encryption is not equal to forced encryption. It is also suitable for the needs of personal encryption. It is even more advanced and easier to use than the existing personal encryption software technology. Therefore, some manufacturers also feel the existence of this market, and have launched personal versions of transparent encryption software.

In short, the development of market demand has spurred the application of transparent encryption technology in various fields. Not only are companies with the need to extend security throughout the supply chain, but individual PC users are also looking for more and better transparent encryption technology products. With the further development of the market, there will surely be more and better products / versions on the market.
