Analysis of Security in Body Sensor Networks Using Binary Sequences

摘要

BSN demands extremely high resource constraints as the heavy weight schemes are not preferred. For the purpose of security, making use of existing information to a BSN is found to be an attractive resolution. In this paper we verified the feature of randomness of 256 - bit binary sequences. The binary sequences are obtained from inter-pulse intervals of 30 subjects who are healthy enough but suffered with myo cardiac infarction and 54 subjects with some other cardio diseases. The time of encoding a binary sequence on a BSN node is about 25ms on an average and occupies 204bytes memory. These binary sequences can be employed as encryption keys which avoids the problem of key distribution over BSN.
