Human Decipherable Encryption Schemeioned in Sect. 2.2, messages are encrypted with a key to ciphertexts as shown in Fig. 4.1a. Without anticipating the following subsections, we point out that messages are first encoded and then encrypted with a key distinguishing between codings and encryptions (see Fig. 4.1). Therefore the followin

Both approaches are not able to ensure perfect non-transferability, but may be sufficient depending on the values to protect.

Summary, Conclusion and Outlookrevious research of visual cryptography, we gave alternative description of visual encryption schemes by distinguishing between encoding and encryption. This allowed us to study the properties of the used encoding and encryption scheme independently. Furthermore, we defined the notion of . (HDES), w

Introduction,ons. In the second scenario, a user has a trustworthy device, but does not want to be tracked by the party verifying the authentication. Additionally, the user should not be able to lend his credentials to someone else. In the next paragraphs we discuss both scenarios in more detail.
