Abstract:
In this work, the RSA (Rivest, Shamir, Adelman) cipher system was
implemented by software. The data in form of speech waveform have been
recorded by using a computer microphone. These digital speeches were
encrypted, and sent via an optical fiber interface card (Fast Ethernet adapter
card) at a bit rate of 100 Mbps to another computer, and then it was
decrypted .The encrypted data were transmitted through the optical system
using a light emitting diode (LED) with a wavelength of 1310 nm and
power of (-14 )dBm.
A multimode optical fiber was used as a channel and Positive Intrinsic
Negative (PIN) photodiode was used as an optical detector.
The power budgets for distances (3, 10, 15, 20, 25) meters have been
.calculated by using the experimental results
In this work, a program was written to support the RSA cipher algorithms
