From: Globemaker on 6 Apr 2010 13:14 Open Source Crypto Processor Project Could be Developed by Volunteers Rev. 0 Proposal for a Computerbunker A gate array vendor will be chosen to provide one logic chip. It will be used to implement the microprocessor with variable instruction sets which can be defined according to a key. The 256 bit instruction width provides uniqueness for each computerbunker owner. A variable compiler will use the key to make executable binary files of instructions that are not useable by any computers not using the owners key. Also, the owners computebunker cannot execute instructions that are compiled for standard CPUs. This provides a logical isolation of the computerbunker from the corruptible internet. Engineers and scientists will be invited to contribute simulations of the logic design, after the FPGA field programmable gate array IC is selected. Your recommendations concerning the chip choices are needed now. One practical value of the resulting microprocessor is due to its independence from government control. A blank FGPA silicon chip can be burned with some ones and zeroes to achieve this.

Could it render computing more efficient? If not, it is the result of computing that counts, not how the computing is done. So, in particular for crypto, I can't see what you intend to achieve. M. K.

One application is for a business to buy a thousand computers for its thousand employees. Then, all of the employees can run secret software that nobody else can use and no virus can infect. This provides "ownership" of the computing power, instead of using a shared operating system licensed with a 50 page agreement from a monopoly that is subject to government parasites. This new computer architecture allows private programs to be executed while never exposing the intellectual property to thieves and government scum. >Could it render computing more efficient? No, it is slower than a 2010 computer and faster than a 1990 computer. >If not, it is the result of computing that counts, not how the computing is done. Yes. The result may be a proprietary computer vision algorithm, for example, that only your team shares. >So, in particular for crypto, I can't see what you intend to achieve. This will be revealed in more detail during the next four days. Imagine Sony using a variable instruction set for playing Sony music for paying customers. Non-paying hackers would be unable to execute the programs without paying for the unique key for the unique instructions that work on a single CPU. All other Sony CPUs will get different instructions to execute the same algorithms.

The idea that you need a gate-array is just a way to make this system more complicated, replacing the BIOS of a standard computer with said ROM would be far cheaper. And note, I said ROM not EEPROM. And even a standard programmable BIOS chip could securely used if the write signal requires a removable jumper to be installed during programming, then removed before the machine is given to it's user.
