Abstract: An ID is being calculated in a manner distributed among devices of the user's personal area network (PAN). The devices communicate in a wireless manner. A server runs a simulation of the PAN. If the server and the PAN calculate matching results, it is assumed that the user's ID is correct for purposes of conditional access. The distribution of the calculation of the ID among the user's PAN devices and its, for practical purposes, stochastic nature render the system very hard to hack.

Abstract: A measure of security is provided by determining authenticity of an object (e.g., credit card, cell phone, car keys, etc.) by letting the object predict at which nodes multiple specific data packets are going to be in a distributed network in the next time slot.

Abstract: A monitoring system monitors a system that has multiple devices that perform respective primary tasks. For the purpose of the monitoring, each device has a finite state machine (FSM) with stochastic non-periodic behavior. The monitoring system simulates in software the behavior of the FSM's. A discrepancy between the states assumed by the FSM's after each time step and the states assumed in the simulation in each time step indicates a failure or a breach of the network's integrity. Hacking such as primary system is practically impossible without being detected. Each device comprises computational resources. In order to reduce the computational environment available to a virus, the idle time of the resources is absorbed by dynamically increasing the complexity of the FSM's.

Abstract: A video game comprises several parts that require attention and response from the user. Interaction with a part that allows for an algorithmic solution can be delegated to a separate controller, thus freeing bandwidth for the user to concentrate on other parts so as to optimize the score.
