Abstract: One aspect of the present invention provides a method and a system for securing data and transmitting it securely. Data is encrypted on a source computer and transmitted to a receiving computer. Users must provide authentication to access the data on the source or receiving computer. The data is not decrypted on the receiving computer until access to it has been authorized. The data can be viewed on the receiving computer or processed to create a print file. The print file can be printed onto pre-printed or partially pre-printed forms. A second aspect of the present invention provides a method for dividing a data file into portions and encrypting the portions. Not all of the portions are encrypted by the same encryption method. An index file describes the portions into which the data was divided and the methods of encryption used to encrypt the portions. The different encryption methods can use different keys. These keys can be produced by multiplying an encryption key by random numbers.

Abstract: An apparatus and method for connecting simulator instruments to a simulator host computer includes a plurality of panel modules, a data bus having a connection to each panel module, and a control computer connected to the data bus and to the host computer. Each panel module further comprises at least one simulated instrument and a local computer. The local computer runs a computer program adapted to the instrument or instruments controlled by that panel module, so that the local computer communicates with the data bus for bi-directional communication between the instrument and the control computer. Each panel module has a unique address on the data bus.
