| Abstract | ||
| The important of reducing a chance of the information being detected during the transmission is Being an issue now days. Some solution to be discussed is how to passing information in a manner that the very existence of the message is unknown in order to repel attention of the potential attacker. The exchanging of the secret key that used in symmetric cryptographic represents a major and the most sensitive part of symmetric cryptographic systems. In different studies, Cryptanalysts usually attack symmetric key cryptosystems through their key management. In this paper, we present a new algorithm to exchange secret keys over insecure communication channel. This algorithm is based on hybridizing the steganography based on LSB (Least Significant Bit) stenography with cryptography using XOR function for exchanging the secret keys. It provides security and reasonable computational cost. Furthermore, it restricts most of the current attacking mechanisms. | ||
