In this paper, we examine the design and application of a one-time pad encryption system for protecting data stored in the Cloud. Personalising security using a one-time pad generator at the client-end protects data from break-ins, side-channel attacks and backdoors in public encryption algorithms. The one-time pad binary sequences from modified analogue chaos oscillators initiated by noise encoded client data locally. Specific “one-to-Cloud” storage applications give control to the end user but without the key distribution problems associated with one-time pad encryption. Development of the prototype was aided by “Virtual Prototyping” in the latest version of Cadence OrCAD PSpice®. This addition allows the prototype simulation schematic to be connected to an actual microcontroller in real time using device model interface for bi-directional communication. using device model interface.
