Encryption Algorithm - what is it?

The Encryption Algorithm is an effective tool for ensuring digital data security.

The development of digital technologies and the introduction of an innovative cryptocurrency system require regular improvement of algorithms, through which the unconditional security of crypto coin users' personal data and their monetary assets will be ensured. For this purpose, various encryption algorithms are used today, such as the Encryption Algorithm. Using such technologies eliminates potential risks of theft and fraudulent activities.

Basic types of encryption

The algorithms used to protect data are regularly improved, considering technology development and available solutions. In total, there are 2 main types of encryption:

  • symmetric, in which one cryptographic key is used for both encryption and decryption of information, which ensures simplicity and high speed of all processes;
  • asymmetric technology involves using several keys linked to each other; one is public (open), and the second is unique (private).

It is rational to use symmetric encryption in transactions between 2 system participants who exchange information. If this works with hundreds or thousands of other counterparties, then only an asymmetric algorithm provides a higher level of protection.

Best encryption algorithm

Different protocols have been used to implement various tools as the technical base has evolved. The most advanced and popular symmetric encryption protocol today is the AES protocol. Structurally, it consists of several block ciphers, which provide different sizes of the blocks themselves and different key lengths.

The basic principle by which the AES algorithm operates is substitution and permutation. There can be up to 14 information transformations in total.

Main advantages of AES Encryption Algorithm:

  • high security, including Wi-Fi networks, various platforms (SSL/TLS), mobile applications;
  • performance;
  • flexibility.

Among asymmetric technologies, the RSA protocol has several advantages. For example, he appreciates the possibility of scalability, thanks to which keys can have different lengths (768, 1024, 2048, 4096 bits). This encryption algorithm is easily implemented in a PKI infrastructure that uses public keys.

The second version of asymmetric technology - ECC - has a shorter length. However, despite this, the level of security when using such a protocol is an order of magnitude higher, as is performance, because this protocol requires less computing power and does not put such a serious load on the network. If RSA is used primarily for cryptocurrencies and email, then the use of ECC is more often noted for encrypting mobile applications and generating digital signatures.
