IV. COMPARISON

1. DES, developed by IBM and based on a design by Horst Feistel, emerged as a widely used cryptographic system upon its release, eventually adopted by the National Institute of Standards and Technology (NIST). It operates as a symmetric-key algorithm for digital data encryption, utilizing a block size of 64 bits and employing the Feistel network structure. Despite its early prominence, DES's adoption waned due to its sluggish performance and susceptibility to security breaches, notably stemming from its short key length of 56 bits. Notably, in 1999, distributed.net demonstrated DES's vulnerability by breaking a key in just over 22 hours, prompting NIST to rescind its standardization. Subsequently, 3DES emerged as a response to address DES's shortcomings and enhance security.
2. Triple DES, also known as 3DES or TDES, officially referred to as the Triple Data Encryption Algorithm, operates as a symmetric-key block cipher, applying the DES algorithm three times to each block. With a block size of 64 bits and a key length of 112 or 168 bits, it retains the Feistel network structure inherited from DES. Despite its robustness initially, the advent of modern cryptology techniques and supercomputing revealed serious vulnerabilities within 3DES. Consequently, the National Institute of Standards and Technology (NIST) deprecated both DES and 3DES for new applications in 2017 and for all applications by 2023. This decision was influenced by the emergence of the Advanced Encryption Standard (AES), which supplanted these encryption algorithms due to its enhanced security features and efficiency.
3. Blowfish, developed by Bruce Schneier in 1993 as an alternative to DES, offers a significantly faster symmetric- key encryption technique with a better encryption rate. Featuring a key length of 446 bits, surpassing DES and 3DES, it poses a greater challenge for key cracking. With a block size of 64 bits, Blowfish finds applicability in software due to its speed and efficiency. However, the advent of AES has shifted focus away from Blowfish, prompting Schneier to recommend Twofish as an alternative. Twofish, boasting a free license and availability for all uses, has garnered attention as a viable alternative to Blowfish in contemporary encryption practices.
4. AES, standing for Advanced Encryption Standard, stands out as one of the most robust encryption algorithms, effectively safeguarding data from malicious actors. Renowned for its strength and efficiency, AES ensures secure online activities without disruption by combining speed and security adeptly. Operating as a symmetric encryption method, AES employs the same key for both encryption and decryption processes. With key lengths available in 128, 192, and 256 bits, each offering varying levels of security, AES boasts a fixed block size of 128 bits or 16 bytes. Distinguished by its structure known as the substitution-permutation network, AES differs from other encryption algorithms, enhancing its resilience and effectiveness in protecting sensitive information.
5. RSA, or Rivest-Shamir-Adleman, is a widely-used asymmetric encryption algorithm renowned for its robust security features. Asymmetric encryption means it uses a pair of keys, one public and one private, for encryption and decryption, respectively. The public key is shared openly, while the private key is kept secret. RSA's strength lies in the difficulty of factoring large prime numbers, upon which its security relies. With RSA, secure communication is facilitated without the need for both parties to share a secret key beforehand, making it ideal for key exchange and digital signatures. Key lengths for RSA typically range from 1024 to 4096 bits, with longer keys offering greater security at the expense of computational overhead. Despite its security, RSA can be slower than symmetric encryption methods, particularly for large key lengths. Nonetheless, RSA remains a cornerstone of modern cryptography, enabling secure communication and data integrity verification in various applications.

With a variable key length, Twofish supports key sizes of 128, 192, or 256 bits, allowing for a wide range of encryption strengths to suit different security needs. As a symmetric encryption technique, Twofish utilizes the same key for both encryption and decryption processes, ensuring simplicity and efficiency in cryptographic operations. Notably, Twofish operates on blocks of data with a fixed size of 128 bits, maintaining consistency in its encryption structure. While AES remains a popular choice in contemporary encryption practices, Twofish's free license and availability for all uses make it an attractive option recommended by Schneier as an alternative to other encryption algorithms.

V. METHODOLOGY

A. Advanced Encryption Standard (AES)

The Advanced Encryption Standard (AES) is a widely adopted symmetric encryption algorithm designed to secure digital data. Established as a standard by the U.S. National Institute of Standards and Technology (NIST) in 2001, AES is celebrated for its robustness and efficiency. The algorithm encrypts data in fixed- size blocks of 128 bits and supports key sizes of 128, 192, or 256 bits, offering different levels of security. As a symmetric key algorithm, AES uses the same key for both encryption and decryption, which must remain confidential between the communicating parties to maintain security.

AES encryption involves a series of transformation rounds, with the number of rounds varying based on the key size: 10 rounds for 128-bit keys, 12 for 192-bit keys, and 14 for 256-bit keys. The encryption process begins with an initial round where the plaintext is combined with the encryption key through an XOR operation. This is followed by multiple rounds of substitution, permutation, and mixing of the data, where bytes are substituted using a lookup table (S- box), rows are shifted, columns are mixed, and the round key is added again. The final round omits the column mixing step but includes all other transformations. Decryption reverses these steps using the same key schedule, ensuring data can be accurately retrieved.

AES is utilized across various applications due to its security and performance. It secures data transmission in communication protocols like TLS/SSL, protects sensitive information in file storage and transmission, and is integral to wireless security protocols such as WPA2 for Wi-Fi. Additionally, AES is employed in full disk encryption solutions like BitLocker, ensuring comprehensive data protection. Its resistance to cryptographic attacks and ability to operate efficiently on both hardware and software platforms make AES a cornerstone of modern data security.

B. Rivest-Shamir-Adleman (RSA)

The Rivest-Shamir-Adleman (RSA) algorithm is a cornerstone of modern public-key cryptography, widely used to secure sensitive data. Developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman, RSA is an asymmetric encryption algorithm that relies on two keys: a public key for encryption and a private key for decryption. This key pair is generated based on the mathematical properties of large prime numbers, ensuring robust security. The public key can be freely distributed, while the private key must be kept secret to maintain the integrity of the encrypted data.

RSA encryption works by transforming plaintext into ciphertext using the recipient's public key, ensuring that only the corresponding private key can decrypt the message. The process involves modular exponentiation, where the plaintext is raised to the power of the public key exponent and then taken modulo a large composite number, typically the product of two large prime numbers. This transformation renders the ciphertext unreadable without the private key. Decryption reverses the process using the private key, restoring the original plaintext. The security of RSA relies on the computational difficulty of factoring large composite numbers, a problem currently infeasible to solve with existing technology.

RSA has a wide range of applications, particularly in securing digital communications and ensuring data integrity. It is commonly used in secure web browsing through protocols such as SSL/TLS, where it helps establish secure connections between clients and servers. RSA also plays a crucial role in email encryption, digital signatures, and key exchange protocols, providing authentication and non- repudiation. Additionally, it is employed in secure file transfer protocols and virtual private networks (VPNs). Despite its strength, RSA's computational intensity and the increasing threat of quantum computing have led to the exploration of alternative encryption methods, though RSA remains a fundamental component of contemporary cryptographic practices.

C. DEFFI-HELLMAN Key Exchange Algorithm

The Diffie-Hellman key exchange algorithm is a foundational protocol in the field of public-key cryptography, enabling secure key exchange over an insecure communication channel. Introduced by Whitfield Diffie and Martin Hellman in 1976, this algorithm allows two parties to generate a shared secret key, which can then be used for symmetric encryption of subsequent communications. The Diffie-Hellman algorithm relies on the mathematical difficulty of computing discrete logarithms, ensuring the security of the exchanged key even if the communication is intercepted. The key exchange process begins with both parties agreeing on a large prime number p and a base g , which are both publicly shared. Each party then selects a private key—let's call them a and b —which are kept secret. Using their private key and the public base, each party computes a public value: A = ga mod p and B = gb mod p. These public values are exchanged between the parties. Upon receiving the other party's public value, each party computes the shared secret key using their own private key: the first party computes s = Ba mod p and the second party computes s = Ab mod p . Due to the properties of modular arithmetic, both parties arrive at the same shared secret key, s, which can then be used for symmetric encryption. The Diffie-Hellman key exchange algorithm is widely used in securing various communication protocols. It is a fundamental component of SSL/TLS, which underpins secure web browsing by enabling encrypted connections between web servers and clients. It is also employed in secure shell (SSH) protocols, virtual private networks (VPNs), and other systems requiring secure key exchange. Despite its strengths, the Diffie- Hellman algorithm can be vulnerable to man-in-the- middle attacks if proper authentication mechanisms are not in place. Nevertheless, its ability to facilitate secure key exchange without prior shared secrets makes it an essential tool in the landscape of modern cryptography.
