Highly efficient one-time pad key generation for large volume medical data protection
Fengling Han, Jiankun Hu, Kai Xi · 2010
In this paper, an efficient one-time pad key generation scheme using grid or space scroll chaotic attractors is proposed. This key can be used for low cost protection of large volume digital medical data, e.g. real-time monitoring ECG data. The one-time pad key is generated from grid or space scroll chaotic attractors to ensure its high-level randomness. In addition, each communicating party needs neither to pre-store nor to distribute the large number of session keys. Simulation results show that this proposed scheme requires low computational power.
