Secure Data Transmission Using Enhanced Key Block-Chain Mechanism

Encryption plays a major role in protecting data transmission over the internet from illegal access. The major security challenge is to protect the keys from an intruder. The sharing of keys among communicating nodes is the biggest challenge before the actual communication begins. To transmit secret data, data security algorithms apply cryptography techniques with suitably decided common keys in a session. The challenge of key sharing is to provide secure access to keys to the communicating nodes. Their communication is supported by the Trusted Third Party (TTP). The security of the key is ensured by continuously updating its value based on some graph nodes. The graph traversal technique determines the complexity of deriving a new key for the next round of communication. The detailed analysis of deriving keys for data encryption further depends on the graph traversal technique.
