PixSel: Images as Book Cipher Keys. An Efficient Implementation Using Partial Homophonic Substitution Ciphers

In this paper we introduce a novel encryption technique, which we call PixSel. This technique uses images in place of literature as the book cipher’s key.

Description
Summary:In this paper we introduce a novel encryption technique, which we call PixSel. This technique uses images in place of literature as the book cipher’s key. Conventional book ciphers possess an unwieldy ciphertext enlargement, creating ciphertexts multiple times the length of the plaintext. As well, there is often the issue of a given book not containing the necessary material for the encipherment of some plaintexts. Wesought to rectify these nuisances with PixSel, possessing a typical ciphertext enlargement of merely 1% to 20% for text. UsingPixSel, there are also no limitations on encipherable data type, given a suitable image.
