To understand Viginere encryption check out the following site:
**broken link removed**
since i will only be using it to encrypt letters it will need 7 bits for the ASCII code of each letter. I use d flip-flops to hold the key-word and then with a MUX deside which letter of the key should be...
Hi, I am designing a circuit to perform Viginere encryption and I have a problem on how to provide the entrances to the circuit. I have to use a keyboard that transforms alpharithmetics to ASCII codes but the one design that I found is too large and too old. Does anyone have an idea on what to...
very interseting seminar topcs
you could organise a seminar on quantum cryptography, it would be very interesting, try the Berkeley Quantum lab for more info on specific subjects :D

any help is gratefully appreciated:D:|:cry:
Re: why do we use complex exponential mathematics in dig com
It's for the same reason we consider both positive and negative frequencies in Fourier transform while the negative ones do not have any physical meanning.It makes calculations and representations of types much easier to understand...
I strongly recommend Wakerly, especially the new fourth international edition, very good work as far as digital design is concerned and also helpful remarks about CMOS.
