What is Data Encryption?

It is indisputable that companies need to protect their content. In view of this, a resource called data encryption appears, which promises to offer greater security to a company's data.

On several occasions, information sent by email within a company is confidential and, therefore, requires extra protection, as a way to prevent cyber attacks that steal this type of content.

Therefore, more and more companies, such as a São Paulo virtual concierge or a law firm, are investing in ways to make sharing this data more secure, choosing to use encryption.

In this article, it is possible to understand more about the subject, knowing what cryptography actually is, how it works and what are its types, so that it is possible to better understand how much it is increasingly necessary.

What is data encryption and how does it work?

In a practical way, it is possible to define encryption as a type of protection that goes beyond the password. Therefore, only those who own it, together with the algorithm, can access a certain content.

Therefore, encryption is responsible for providing secure communication when there is the presence of third parties or malicious people. Its main process is to transform plain text into encoded text.

Therefore, a portable air conditioning maintenance company , for example, can use encryption to make its information more secure. This is because this feature has several functions, such as:

Information integrity;

Data availability;

Confidentiality;

Authentication of senders and recipients.

In view of this, the operation of cryptography takes place through the use of an algorithm, which transforms a simple input text into a coded one that must use the same key.

For the algorithm to be considered secure, the attacker cannot be able to determine any property of the plain text, or even the key of that text that was encrypted.

Thus, when a server communicates with a client, it is possible to prevent intruders from gaining access to the data contained therein. It is even interesting to mention that protections are provided by cryptographic protocols, such as SSL/TLS.

Encryption can also provide greater protection for data at rest, such as data stored on disk, which helps prevent confidential disclosure in the event of theft or theft of physical media.

What are the types of data encryption?

Both the nearest veterinary clinic and an accounting office can use cryptography in their daily lives. But, it is necessary to know beforehand the existing types of this resource. Are they:

Symmetric encryption;

Asymmetric encryption;

Quantum cryptography;

Homomorphic encryption.

Symmetric cryptography is one that uses a unique key to transform and decrypt a message. Therefore, the secret is shared. In contrast, asymmetric cryptography uses a pair of keys, one public and one private.

These keys are related through an algorithm, and the encrypted data can only be unraveled when these keys match.

Quantum cryptography is one that uses essential features of quantum physics. Therefore, it ensures the security of information, and eliminates the issue of key distribution. 

Finally, there is also homomorphic cryptography, which is different from the other options, as it performs the computation to execute the encrypted data directly, without the need for access through the secret key.

Therefore, the result of the calculation will remain encrypted, but later, it is revealed by whoever has the secret key.

In any case, any company that has a structure with an 8-seat workstation , in which several people work very close to each other, can be relaxed, since even in such cases it is possible to use cryptography.

In fact, any company in the market that deals daily with data must prioritize its security, so that this information receives its most appropriate layer of protection and prevents leaks of confidential data.

Final considerations

It is undeniable that, every day, companies in the market receive and need to deal with a large amount of confidential information, which should not be revealed and therefore depend on resources that allow for this extra protection.

Given this, encryption proves to be an interesting resource for companies and the most varied segments, who can bet on this tool to protect their data and to ensure that they do not leak and bring harm to everyone.
