Abstract

This paper presents a survey of key distribution schemes for wireless sensor networks. This survey includes the new approach of key distribution using the piggy bank method. Different Network architectures and different key pre-distribution schemes are described. The survey includes the use of the piggy bank approach to cryptography in which part of the key is pre-distributed and the remainder is varied in the application.
