Lattice based cryptography for electronic travel documents

The world has become one globalized platform with the advent of sophisticated embedded systems as it allows people to communicate in the local town to the farthest town on this earth. This includes communicating via mobile phones Internet or sending an instruction to microwave oven television and other wireless systems. We make assumptions that our communication remains confidential when we communicate using mobile phones or Internet. We assume that the payment gateway will be authenticated and our banking details will remain confidential while accessing Internet banking. We assume that our instruction sent to the wireless embedded systems will be received exactly as we had sent (Integrity) i.e. the message sent by us and the message received by the embedded system will be the same. We make these assumptions as there will be certain protocols followed to maintain security standards.
