Maitra and Paul (2008) [8] worked on analyzing RC4 based on weakness in biases and proposed additional layers over the key scheduling algorithm and pseudorandom generation algorithm.
Key scheduling algorithm is also used in AES to provide keys to each of the rounds.
To apply the association rule mining, we divided the data into two groups: constituent elements of ciphers (key size, block, S box, round function, rounds, key scheduling) and performance parameters (code size, RAM size, execution time).
The RC4 stream cipher uses the key scheduling algorithm (KSA) and the pseudo-random generation algorithm (PRGA), which are executed sequentially.
In a cipher algorithm a secret key is used to create the number of round keys (sub-keys) according to specified key scheduling algorithm.
Zoltak [8] proposed Variably Modified Permutation Composition (VMPC) which was designed to be efficient in software implementations and solved a weakness found in the RC4 Key Scheduling Algorithm (KSA) that had been described by Fluhrer et al.[9].The structure of Pseudo-Random Generation Algorithm (PRGA) in VMPC was more complex in comparison with the RC4 which makes it more resistant to attacks.
Refineries, therefore, can increase agility and perform all key scheduling activities within the same platform.
One of the main contributions of this paper, together with the seeding and extraction algorithms, is the output filter, which is a new design based on the key scheduling algorithm of RC4 (see [8]) to construct four 8 x 32 s-boxes; it can be adapted to other generators, incorporating the concept of key scheduling to PRNGs.
Appropriate for graduate students, the monograph analyzes the key scheduling algorithm of RC4, different algorithms for recovering the secret key of RC4 from the state information, and the pseudo random keystream generation algorithm.
In addition, components for data processing and key scheduling part are shared.
NBC and ABC probably can't afford to play things too safe this year, as both nets have several key scheduling holes to fill.
In 2001, when Scott Fluher, Itsik Mantin and Adi Shamir published "Weaknesses in the Key Scheduling Algorithm of RC4," and the Shmoo Group released the beta version of Airsnort, compromising a WEP key was a daunting task.
