The ideas of these lines came by taking into consideration the way that modern servers convert the code of the web pages, showing to the users only a slide interpreted in the HTML language; in this way the code and the algorithms are not accessible - see for example how this machanism is implemented in the PHP language.
This proposed cryptographic circuit has to take the role of the PHP language making hidden to the users the code that is running on the CPU.
How this circuit has to work is similar to the way of crypting with two locks but it will use instead of these locks some internal registers which to not be accessible to the users.
All the executable codes have to be converted using a generic language and a table in which are stored the correspondences between these new generic operators and the common ones from the ASM language.
The circuit will have the role to update the content of the internal registers proposed with the new correspondence and will make also the link to the HW.
In this way the code that is executed will not be accessible to the common users and some parts of programs (serial numbers of the setups) can be easily very good protected.
With this kind of circuit any activity of programs like macros recording > recording/merging macros from any application - can be avoided.

ALU ADD Circuit

The basic for this proposal is the classic circuit of adding two numbers on multiple bits.
Looking into the 2 dimensional array of the obtained appling the binary XOR operation on the bits of all the pairs of numbers smaller than a number it can be seen that instead of doing a+b (a and b are decimal numbres) we can do:
x= a xor b
y= 2*(a and b) and in approx. 50%, a+b = x or y and in the other 50% a+b = x+y this mean that we have to introduce again x and y in the ADD circuit.
If we draw the circuit only for adding 2 bits x and y to be introduced in the circuit means to apply some XOR gates to the binary representation of them.
The basic idea of this disclosure is focused on the 50% of cases in which a+b = x or y.
For this I formed a circuit in Tina ver. 6.0 a model of circuit that uses tri state buffers for selecting the cases when we have to use the XOR gates or the OR gates; instead of using a 3 state buffers there can be usesed one transistor.
In this way we avoid the usage of the XOR gates using only 1 transistors for each bit/line and OR gates.
In this way the timeof computing wll be faster and only the energy consume will be lower, beacuse of using less number of transistors.
