A Method of Probabilistic One Time Programs with Information Theoretic Security

University of Vienna Background
To combat software piracy, various safety checks can be built into computer programs. One such method is that of ‘one-time’ programs which can only be executed a single time. By the use of this quantum technology, a classical program can be only allowed to operate a single time, preventing copying of the software
Technology Overview
This technology, developed in collaboration with the Singapore University of Technology and Design, allows programs to be sent securely using single particles of light (quantum photonics). These particles of light do not merely describe the program but are the physical logic of the program. The interaction with the light is the act of using the program. This is a completely new and novel way of performing a computation and it provides security to the program which is guaranteed by the laws of nature – not by the assumed computational power of an adversary.
