Outer-Convex Dominating Set in the Corona of Graphs as Encryption Key Generator

Blog Article

In this paper, we present a new type of symmetric encryption summer beauty ornamental onion by converting the classical monoalphabetic affine cipher into a polyalphabetic cipher.The proposed encryption utilizes the properties of outer-convex dominating set in the corona of graphs to generate random keys verbatim coupons from the shared keyword to every character of the message.The new encryption eliminates the weaknesses of affine cipher, thus increasing the level of confidence for exchanging messages.
