The key generation problem in the two-way relay channel, in which there is no direct channel between the key generating distributions. We propose an effective key generation scheme that achieves a substantially keys than direct channel. Unlike existing schemes, there is no need for the key generating terminals to obtain. Secure key distribution schemes establish communication between a group manager and group members through an unreliable broadcast channel. The improved efficiency for key management process is realized by periodically refreshing all public private key as well as the multicast keys in all the nodes using one newly generated function. The article classifies and compares the most significant key distribution schemes, key distribution algorithms, at the predistributed secret data management, and self-healing mechanisms. It consists of polynomial-based algorithms, exponential arithmetic based algorithms and hash-based techniques. Proposed classification is based on the applied cryptographic primitives.
