Top 5 Strongest Data Encryption Algorithm in Cybersecurity
Data encryption is a security method that helps protect internet users’ data. In data encryption, one can protect the data by encoding it so that it can only be decrypted by the user who holds the correct encryption key. When users without the proper encryption key try to lay their hand on encrypted data, they either see gibberish or unreadable data.
Data encryption is extremely crucial nowadays with the rise of cybercrime. It helps protect the users of their confidential data. Almost all communication forms on the internet and different data types can be encrypted. It is why many popular messaging apps and cloud services can provide data encryption to their users for an added layer of security.
The Importance of Data Encryption
Data encryption helps authenticate the actual owners of the data and, thus, prevents data theft. It also provides privacy to the user. For instance, only the receiver can access the data if you share your IP address after finding it out on What Is My IP and encrypting it. In addition, the privacy that data encryption brings with it helps protect it from other users.
Data encryption is also vital for many businesses because of the government’s regulatory compliance. Many governments impose this regulatory compliance to protect the data of the customers. Lastly, it provides robust security for all kinds of data.
There are many types of data encryption available. Therefore, understanding the different data encryption algorithms in cybersecurity can help one choose the best encryption for their requirement. Below is a list of the top five most robust data encryption algorithms in the cybersecurity domain.
1. Advanced Encryption Standard (AES)
AES is so efficient that even the United States government uses it to encrypt their data. It can use 192- and 256-bit keys; however, it is most efficient for the 128-bit form. AES is a standard encryption method that protects against different cyberattacks. However, it is prone to brute force.
Messaging apps commonly use AES. It provides both the sender and receiver with a single key for encryption and decryption.
2. Triple DES
Triple DES has evolved from the previous Data Encryption Standard algorithm. The developers felt the need for Triple DES when the hackers came to know how to breach the Data Encryption Standard algorithm. It receives its name from the fact that it employs the triple DES algorithm to protect all the data blocks. Furthermore, all the individual blocks house 64-bit data.
The key length of Triple-DES is usually long, which makes it one of the most robust encryption types. Many users employ Triple-DES to encrypt UNIX passwords.
3. Blowfish Encryption
Blowfish Encryption uses a single key for encryption and description of the data. The USP of this encryption lies in its 18 subkeys, 16 rounds and four S-boxes. Furthermore, it breaks the messages into 64-bit blocks, which are then encrypted individually.
Blowfish encryption is extremely popular because of its speed and flexibility. It is free in the public domain, and anyone can use it. The most common usage of Blowfish encryption lies in eCommerce platforms and password management tools.
4. Twofish Encryption
Twofish is the successor of Blowfish. Just like Blowfish encryption, it again encrypts the data in 16 rounds, irrespective of the key size. It uses one key for encryption and decryption. Additionally, it carries overlapping features of Blowfish and AES encryption.
Twofish encryption is also highly flexible, and it supports many options. For instance, depending on your requirement, you can go for fast and slow encryption using Twofish encryption.
5. RSA Encryption
The RSA algorithm is one of the oldest encryption algorithms developed in the 1970s. Even today, RSA encryption is widespread because of its power. In this encryption, two large prime numbers are multiplied to create a large prime number. To know the key, one must reverse the entire process to figure out the original two prime numbers.
The calculation is tough to crack and is very time-consuming. Also, this encryption creates two keys simultaneously, which include both public and private keys. The public key encrypts the data, whereas the private key is designed for decryption. Without the correct decryption key, the RSA security algorithm generates a massive gibberish of data that consumes plenty of resources.
To choose the correct encryption key for your requirement, you should consider the security requirement through intelligent assessment. Then, you should select the right encryption tool based on its pros and cons. Lastly, deploy the chosen encryption to protect all kinds of your data.
