You are to write a short APA style paper of 2-3 pages on standards used for encryption. The paper should research and discuss two encryption standards and provide supporting examples of where these standards are applied in a Public Key Infrastructure.  Suitable research needs to be applied and demonstrated in the paper.



Title: Encryption Standards: A Comparative Analysis and Application in Public Key Infrastructure

Encryption plays a crucial role in safeguarding sensitive information and ensuring secure digital communication. As technology continues to evolve, encryption standards have become vital for maintaining privacy and protecting data from unauthorized access. This paper aims to explore and analyze two prominent encryption standards, discussing their application in a Public Key Infrastructure (PKI). By examining the strengths and weaknesses of these standards, we hope to highlight their significance in ensuring robust security protocols.

Literature Review:
1. Advanced Encryption Standard (AES):
The Advanced Encryption Standard (AES) is widely regarded as one of the most secure symmetric encryption algorithms. Introduced by the National Institute of Standards and Technology (NIST), AES has gained global acceptance due to its effectiveness and efficiency in data encryption. AES operates with various key sizes, such as 128-bit, 192-bit, and 256-bit, offering a high level of security against brute-force attacks (Daemen & Rijmen, 2013). For example, AES-256, which uses a 256-bit key, is considered unbreakable even by the most sophisticated supercomputers available today.

2. Rivest-Shamir-Adleman (RSA) Algorithm:
Unlike AES, the Rivest-Shamir-Adleman (RSA) algorithm is an asymmetric encryption method, which utilizes public and private keys. RSA is widely employed in PKI, where it ensures secure authentication, confidentiality, and integrity of electronic communication (Boneh & Shoup, 2017). RSA relies on the computational difficulty of factoring large prime numbers in order to decrypt the encrypted data. The security of RSA lies in the difficulty of reversing the encryption process without knowing the private key.

Application of Encryption Standards in PKI:
Public Key Infrastructure (PKI) is an essential framework for managing digital certificates, which are used to verify the authenticity and integrity of electronic communication. Encryption standards like AES and RSA are integral components of PKI, providing secure encryption, digital signatures, and certificates. AES is commonly used in symmetric key encryption for securing the transmission of large amounts of data within the PKI infrastructure. On the other hand, RSA is utilized for asymmetric encryption, where it facilitates secure key exchange and ensures the confidentiality of sensitive information (Liu & Kandhasamy, 2017).

In conclusion, encryption standards such as AES and RSA play a significant role in guaranteeing the confidentiality, integrity, and authenticity of digital communication in the modern era. AES ensures secure symmetric encryption, while RSA provides reliable asymmetric encryption, making them fundamental tools in PKI. Understanding the strengths and applications of these encryption standards is crucial for designing robust security systems in various domains, including finance, healthcare, and e-commerce. Further research and development in encryption standards will continue to enhance the security landscape, making data protection a priority in the digital world.
