Safety remains one of the most important factors whenever we surf the internetespecially when they must be introduced credit card numbers, enter payment platforms, among many other places where they are handled private and important data.
That is why today data encryption has become a very important procedure to be able to protect files, data or any other document that is handled on the webespecially with the proliferation of cloud storage services where more and more there are millions of information that is in this mobility.
All this has led to hackers have one greater ease when wanting to steal some type of data or information. One of the ways to be able to have all this protected and safe from any cybercriminal is by encrypting the information. That is why here we are going to teach you what it is to encrypt data and what this function is for.
What is data encryption and what is it for in computing?
encrypt data has become is one of the best ways to be able to protect users’ personal and important informationthis is how this consists of placing a security key to all information deemed necessary where only people with access to said key will be able to read them. Therefore, the goal of all this is to be able to ensure the protection of digital data and offer them a greater peace of mind for users.
Although this process can involve advanced mathematical calculations, performing this procedure is not difficult, so almost all people can be able to do it. To do this, you simply have to search for the information you want to cover and through secret codes Your information will be hidden, in this way only those people who have said information will be able to enter. access to researchotherwise no relevant text will be found in it.
This is how all the information that is encrypted will have very advanced security levels capable of protecting any type of online procedure to do with them. Some of the most important data for encrypt are the credit card numbers, personal data or private information that is shared over the network.
What are the main elements of data encryption?
the encryption is composed of two fundamental elements for its optimal development, this is about the key and the algorithmsit is these two functions that allow users to protect your data and in that way restrict access to it by third parties. This is how here we are going to explain a little more about the two main elements of this security system.
Key code
The main element to be able prevent third parties from accessing the files is the key or password, which is the derivative of the public key of one party and the private key of another party. Therefore, the password that is shared is used to encrypt subsequent communications between the partiesThese parts usually they do not usually have prior knowledge of each otherwhere you end up using a symmetric encryption system.
In this way, the creations of public keys and private keys can be generated over and over again each time run security protocolthis will always guarantee information protection.
Algorithm
The They are a fundamental piece for what it is the protection of an access control system, since they are the ones who are going to guarantee the invulnerability of communications between the different parties. Therefore, the use of algorithms is essential for this type of mechanism which can constantly be receiving attacks on the files that are exchanged.
It is essential to mention that today there are different security levels for communicationswhere there is currently two fundamental algorithms for them, which we show you below:
AES (Advanced Encryption Standard) algorithm
Considered today as one of the most stable and securespecially created to maintain the privacy of secret information handled within the National Security Agency of the United States. This is how all this is based mainly on permutations, substitutions and linear transformations that run on 16 byte blocksand which are repeated simultaneously.
Being such a safe algorithm, it is frequently used to encrypt the information contained in the world’s banks, governments and maximum security systems. Until now no known attack that you have achieved breach your protection system.
3DES (Triple Data Encryption Standard) algorithm
He is specialized in the DES algorithmwhich aims to apply a large number of basic operations In order to convert a document into a encrypted document. To do this, use a cryptographic keythus preventing third parties from accessing said information contained there.
This is how this algorithm is responsible for performing a triple cipherthat is to say, that apply three times with three different keys which makes it almost impossible to break. This type of system is currently used by a large number of electronic payment pages, where it protects the identity of credit cards and personal data.
What are the different types of data encryption that have been developed so far?
As time has passed the types of encryption have been changingthis is how we can currently find different kinds of them either according to its key, its properties and its algorithms. Therefore, below, we are going to explain what each of them means.
According to your key
This type of encryption may vary depending on your key typeeither a symmetric or asymmetric encryption, This is how we explain each of them here.
Symmetric Encryption
So much the encryption and decryption keys are the sametherefore, the communicating parts They should have the same keys so that completely secure communication can be established. In other words, the same is used key to encrypt and decrypt the message that both the sender and the receiver must know.
Asymmetric Encryption
This system is mainly based on the use of two keyswhat he is public key system that anyone can use to encrypt the messagebut in this case only the receiving part is the one that will have password access to read the message. This allows all this information to be disseminated without much problem to all those people who need send encrypted information.
While the other type of key is the one that is privatethat is to say that it cannot be at anyone’s reach, and will only be known by its creator. In the same way this password type can never be revealed which will prevent third parties from accessing the documents. Therefore, the use of a symmetric or asymmetric system will mainly depend on you need them from the user. Nevertheless, the symmetrical system has shorter calculations what do you require less times than those of system asymmetric.
According to your algorithm
The other types of encryption that can be found today are according to their algorithm, in which two types can be distinguished:
stream encryption
In this case the encryption will be done bit by bitand are mainly based on the creation of extremely long keys which are used for both encrypt how to decrypt the information. They can be used in a only use or generate them using a pseudorandom key generator what generates a pseudorandom binary sequence from a startup password.
In most cases, for the calculation of this type of key directly intervenes in the encrypted message up to that moment. Furthermore, it is important that the encryption in this type of algorithm is always kept in secrecy for security reasons.
Block Ciphers
This type of block algorithms consists in the first instance break the message into blocks that have the same length, then each of these blocks will be converted into an encrypted message block through a set of operations that will be carried out simultaneously. In this encryption type operations are performed in each of messages such as permutation and substitution of elements. Furthermore, in this type of password algorithm can be so much symmetric as asymmetric.
According to its properties
Another of the types of encryption that are currently found is according to their propertiesin this case algorithms are grouped according to their function, its characteristics and properties.
Some examples of these include the following:
- Secure forward encryption: The main idea of this type of system is that you can have a static public key don’t changeand also to be able to count on a procedure that is in charge of change that password automatically from time to time after performing some procedures.
The process for the calculation of the key it must be in only one direction, which makes it easy to calculate, but the inverse problem must be complicated, this means that, if the current key is violated, the old keys must remain in the system. Therefore, even though current key is decrypted, old keys are kept.
Two more types of encryption:
- Threshold encryption: When it comes to a threshold encryptionis usually done with the notation “t-threshold” in order to be able to indicate what the threshold value of the system is. All this is done with the aim of being able to distribute functionality in order for the different entities to cooperate, such as distribution of responsibilities and fault tolerance.
- Identity-based encryption: It is characterized mainly by the use of user identity attributesas it are email addresses, domain names, personal data, local address, among many others. From this it can be encrypt and verify signatures, without the need of require digital certificates.
This has meant that nowadays it is not necessary manipulate these certificates which makes it much easier to manipulate users’ cryptographyas messages will be able to be encrypted by people before these are manipulated by any other entity.
- deniable encryption: This type of encryption is responsible for denying the convincing way in which the data is encrypted or being able to decrypt it. Usually a ciphertext can be decrypted into a single plaintext, but in the case of deniable encryptionallows the user to decipher texts and produce a simple text only when necessary.
Even though I’m in the condition of revealing a plain textthe attacker cannot reveal some of the differences between the true and alternate text.
- Isolated Key Encryption: Isolated key encryption is usually split into N periodswhere the secret keys…
