 Cryptography is the art of achieving security by encoding messages to keep the information non-readable. Cryptography actually is a mathematical scrambling and unscrambling of data to achieve, Confidentiality (Readable only to sender and receiver); Integrity (not modified by any one to integrity of message); Non repudiation (sender can't refuse the claim of not sending); and Entity authentication. While sending or receiving the data, special keys are used to encrypt/decrypt data to verify the original contents. This key makes the process of cryptography secure. There are two approaches for the generation of encryption/decryption keys i.e software and hardware. The purpose of this paper is to generate encryption key using hardware technique. To design electronics circuit basic concept is derived from encoding and decoding of data vis four different channels at different times. Selections of channels will be guided by timer and decoder circuits. one form to another from at transmitter end receiver end respectively. The purpose of this paper is to generate the key code using electronic circuits to make the data secure.
