Cryptosystem Based on Fuzzy Theory

Ashutosh Pandey, Sunil Kumar Kashyap


This paper proposes a cryptosystem whose security comprises with the membership function of fuzzy. The security lies with the linguistic and numeric representation of information and its transformation by fuzzy. The one way hash function is substituted to membership function. The key generation and encryption comprises with fuzzy set and fuzzy logic respectively. Thus, the proposed system provides the security against all attacks by linguistic transformation rather than numeric representation. This is also an efficient cryptosystem by grading.

Keywords: Fuzzy, Cryptosystem, Membership Function, Fuzzy Set, Fuzzy Logic.
