<p>The present invention relates to a method for visual authentication of high-entropy parameters by means of multi-step progressive visualization on a receiving application by a user, more particularly to allow machine-to-human authentication, which is unaddressed in existing solutions and security protocol frameworks. One of the advantages of the present invention is that it provides for representation of long high-entropy codewords as perceptually significant visual images on graphical displays. These codewords occur in the context of cryptographic protocols, and typically range in length from 128 to 1024-bits. By computing representation at more detailed scales of resolution in progressive steps, this allows human visual inspection which is both secure, effective and ergonomic. Another advantage of the method of the present invention is that it computes visually simple (and therefore ergonomic) representations at each step of progressive computation, with the complexity of visualization process (as would necessarily arise from entropy content of cryptographic codewords) dispersed over the multiple steps of progression. This provides for the user to determine whether visualised cryptographic input is authentic by means of a process which can range from simple to exhaustive, with the level of thoroughness proportional to number of user interactions with the particular visualization object. Authentication of the input codeword would be accomplished by means of comparing test visualization against reference visualization at each progressive step, the latter of which is executed on platform deemed to be trustworthy by the user.</p> |
