Utilising Simulation Technique to Examine the Security of Various Key Sizes on Rijandael, FPA, and RC4 Algorithms in VB.NET
Abstract
A breach of the unprotected electronic data might result in sensitive or confidential information being taken, changed, copied, sent, viewed, or used without authority. This study focuses on having security testing of Rijindael, Rivest Cipher4 and Format Preserving Algorithms in VB.Net Using simulation Comparison Techniques by comparing three (3) encryption algorithms by simulation method to know the most secured algorithm in VB.Net of different minimum and maximum key sizes to determine the security. The study also evaluate the three most common encryption algorithms like Rijandael, Rivest Cipher4 and Format Preserving Encryption Algorithm. A simulation comparison were conducted for those three (3) encryption algorithms at different settings for each algorithm such as minimum and maximum key size change to know which among those algorithms performs cryptography in the most secured way. Results from simulation analysis showed that Rivest Cipher4 (RC4) is the best algorithm in terms of security among the other compared contenders using the higher key size and lower key size as it maintain an average time for each key size both (Min & Max) followed by Rijandael and format preserving algorithm. This study therefore recommend the adoption of Rivest Cipher4 (RC4) in VB.Net in terms of secured cryptography.
