A Systematic Literature Review on Symmetric and Asymmetric Encryption Comparison Key Size

Symmetric and asymmetric encryption methods are used when a web browser is used to reply to emails, submit website forms, and perform similar activities. Key size is essential to enable security, which means the longer a key is, the better security can be ensured. Purpose: This review aims to present an overview of the critical size length, which is significant against different types of cyber attacks. Methodology: This research study is based on systematic literature review and secondary data analysis. Results: The symmetric and asymmetric key sizing participate in enabling data security and protection. Conclusion: Different cryptographic techniques will contribute to highlight the best approach that can be employed to maintain confidential data and address related issues within symmetric and asymmetric encryption key size.
