“…Blowfish uses a large number of subkeys that can be precomputed before any data encryption or decryption. Blowfish consists of an array also called as P-array which comprises of 18 sub-keys [28]. This prevents attackers from figuring out how the sub-keys were generated, and then gaining access to all the other known keys.…”

-In web environment, browser extension extends its functionality by retrieving, presenting and traversing the information through web browser. Browser extensions run with 'high' privileges which consequences, vulnerable web browser extensions to steal user's credentials and trap users into leaking sensitive information to unauthorized parties. One of the attack known as Colluding browser extension attack causes privacy leakage of share data in web browser through extensions. This paper, proposed Defacement of colluding Attack (DCA) mechanism to secure user credentials and confidential information over web browser extension. DCA mechanism encapsulate padding with blowfish algorithm to encrypt sensitive information before sharing it over common memory location. Finally the comparison evaluation of proposed mechanism is carried out with twofish, threefish, 3DES and DES on standard parameters such as encryption time, decryption time, key-length, throughput, attacks and level of security.

“…Blowfish may be a quick, compact, and straightforward block encoding algorithm with variable length key permitting a trade-off between speed and security. The block size is sixty four bit and uses 16-round Feistel Cipher and enormous key-dependent S boxes [11,12]. The algorithm keeps 2 subkey arrays; 18entry P-array and 4 256-entry S-boxes.…”

Authentication and Encryption with Key Exchange are the key concepts in Cryptography, which have been continuously being targeted. Many Security Algorithms are developed as research outcome and they are broadly classified into Symmetric and Asymmetric algorithms. Symmetric Algorithms are conventional which use a common secret key that is transmitted by using physical or other communication channel. Data Encryption Standard, Triple Data Encryption Algorithm, International Data Encryption Algorithm, Blowfish and AES are the algorithms that are categorized into Symmetric. In order to make key distribution easy, Asymmetric Key algorithms such as Rivest Shamir Adleman, Diffie Hellman, Elgamal, Digital Signature Algorithm and Elliptic Curve Cryptography, are used for Encryption and Authentication where secret key remains with generating user. Rivest Shamir Adleman, ElGamal and Elliptic Curve Cryptography are the most widely used public key algorithms that perform Key Exchange and used for both authentication and confidentiality. Digital Signature Algorithm is a generally applied digital signature system where as Diffie Hellman is used only for Key Exchange. This paper presents a review of the renowned Symmetric and Asymmetric algorithms. The specified algorithms are developed and test results are presented comparing the performance and key sizes.

“…It takes a variable-length key, from 32 bits to 448 bits, making it ideal for both domestic and exportable use (Alabaichi, Ahmad, & Mahmod, 2013). It is a freely available symmetric block cipher designed in 1993 by Bruce Schneier.…”
