Introduction

Encryption helps encode information into specific symbols that protect data from viruses and hacks. This technique is commonly used in the IT and engineering spheres when professionals need to secure big data and transfer it to the customer. There are two types of encoding which are called symmetric and asymmetric, and they are used in diverse cases like data integrity, authentication, privacy (Kaur & Kumar, 2020). Data protection is considered one of the most important aspects while coding. Consequently, this essay will compare two types of encryption techniques and evaluate their importance in protecting big data.

Encryption Techniques and Their Importance

Symmetrical encryptions have special algorithms which encrypt and decrypt information. There is only one key called a secret key, and it converts data into code that is not understandable for anyone. Once the encoded message is received by those who need it, parallel algorithms transform the code into the original form. The information can be accessed using a specific password available for those who work with the code. This password is generated by the systems, including random numbers and letters. Every sphere that requires information encryption and password generation has unique algorithms not available for those who do not work in a particular area. According to Kaur and Kumar (2020), there are two types of symmetrical encryption called ‘block algorithms’ and ‘stream algorithms.’ Blocks transform information into chunks of electronic data, and streams store data in a structured sequence.

Asymmetrical encryption has approximately the same functions as symmetrical techniques, using two separate cryptographic keys. These keys are commonly known as ‘public key’ and ‘private key,’ and they have diverse responsibilities (Kaur & Kumar, 2020). The public key is often used for encryption, and the private key is famous for the decryption process, and this type of information can be accessed only with the use of a specific password. Both keys are mathematically connected, and their parallel generation helps secure the encryption process.

Both techniques are used to secure data and ensure a safe transfer of information. The keys used in the process allow developers and customers to have protected access to specific data that other people should not reveal. Asymmetric and symmetric techniques are usually used by banks where all transactions should secure and transferred in the particular code to decrease the risk of stolen money or hacked accounts. Software developers can decide which type of encryption process they like most and what can be more helpful. For more easy projects symmetric technique can be used as it requires less time to be generated. At the same time, more complicated schemes require professionals to use asymmetrical methods.

Nevertheless, it is important to understand the most visible differences between these two types of encryption methods. For instance, the text is shorter in the symmetrical method, and the generation of codes does not take much time. However, asymmetrical encryption requires developers to encode more information and make it more complicated. Moreover, the asymmetrical type is more secure than symmetrical and used in serious areas. The symmetrical technique is easy to use because the encryption and decryption are conducted using one specific key, while asymmetrical requires developers to combine private and public keys. Nonetheless, symmetrical encryption is an old version of encoding, and asymmetrical, in this case, is considered to be more reliable.

Symmetrical encryption is more suitable for big data as it does not require long messages, and long messages can be encoded quicker. Big data includes many complicated information pieces that constantly renew and should be protected. Consequently, the symmetrical technique uses an easy method that allows developers to preserve data efficiently. The asymmetrical technique is rarely used in massive encryption processes as it increases the length of the cryptogram, which is not beneficial in the encoding process. The price, in this case, rises significantly, and the demand for this method decreases. Moreover, the symmetrical method uses less power and may provide encryption and decryption simultaneously. The hybrid technique can also be useful in data protection, but it isn’t very easy, and software developers should have experience in combining different techniques. Nevertheless, the hybrid method helps control encryption during the session, and when it finishes, the developer can save changes or leave them unsaved. ‘Session key’ is generated for the single access and is not saved in the system. These methods help ensure data security and test different changes that might affect big data.

Conclusion

In conclusion, encryption helps to protect different types of data, and diverse techniques give developers the chance to test or adjust changes to specific information. Symmetrical and asymmetrical encryption techniques are the key aspect of the concept, and they allow IT professionals to work with different amounts of data. By understanding the key similarities and differences, encoders are able to use both techniques in the right way. Each method has advantages and disadvantages, and if people understand how to decrease the negative effects caused by these techniques, the data encryption process can become more reliable and secure.
