An Efficient Cryptosystem Using Playfair Cipher Together With Graph Labeling Techniques

An Efficient Cryptosystem Using Playfair Cipher Together With Graph Labeling Techniques B Deepa V Maheswari V Balaji Abstract Cryptography is the branch of Discrete Mathematics which deals with the transmission of secret communications between intended parties without the knowledge of third party. Graph theory is the enchanting field if Mathematics that designate integers to edges and vertices through some established functions. In current scenario security of communication plays a crucial role in any telecommunication or network applications. In this paper we have proposed an efficient cryptosystem using play fair cipher together with graph labeling to safeguard our secret text from unauthorised persons. Here we employ the substitution cipher namely Play fair cipher for plaintext encryption and ourencrypted text in the form of Cipher Graph is forwarded to the receiver which on application of graph labeling yields our plaintext. Thus a fusion of the techniques Cryptography with Graph labeling provides ultimate security for secure transmission of data or information at various levels. 07 01 2021 022016 http://dx.doi.org/10.1088/crossmark-policy iopscience.iop.org An Efficient Cryptosystem Using Playfair Cipher Together With Graph Labeling Techniques Journal of Physics: Conference Series paper Published under licence by IOP Publishing Ltd http://creativecommons.org/licenses/by/3.0/ https://iopscience.iop.org/info/page/text-and-data-mining 10.1088/1742-6596/1964/2/022016 https://iopscience.iop.org/article/10.1088/1742-6596/1964/2/022016 https://iopscience.iop.org/article/10.1088/1742-6596/1964/2/022016/pdf https://iopscience.iop.org/article/10.1088/1742-6596/1964/2/022016/pdf https://iopscience.iop.org/article/10.1088/1742-6596/1964/2/022016 https://iopscience.iop.org/article/10.1088/1742-6596/1964/2/022016/pdf Gallian 2018 A Dynamic Survey of Graph Labeling Harary 1969 International Journal of Engineering and Technology Selvarajan 7 750 2018 10.14419/ijet.v7i4.36.24234 Prime Graceful Labeling Journal of the Egyptian Mathematical Society Zeen EI Deen 27 20 2019 10.1186/s42787-019-0025-x Edge even graceful labeling of some graphs Khan Design and Analysis of Play fair Ciphers with Different Matrix Sizes UlabJournal of Science and Engineering AhnafTahmid Shakil 5 An Efficient Modification to Play fair Cipher International Research Journal of Engineering and Technology (IRJET), e-ISSN: 2395-0056 Deepthi 04 A Survey Paper on play fair Cipher and its Variants Maha IJITEE Karthiga 9 2020 Enhancing Security in Cloud Computing using Play fair and Caesar Cipher in Substitution Techniques Xiaomei 10.1109/ICISE.2010.5691730 1 2010 Journal of Environmental Science, Computer Science and Engineering & Technology, JECET; March 2019- May 2019; Sec.
