Identity-based key agreement and encryption for wireless sensor networks

It is an important challenge to find out suitable cryptography for wireless sensor networks (WSN) because of the limitations of power, computation capability, and storage resources. Many schemes based on public or symmetric key cryptography are investigated. Recently, a practical identity-based encryption technique is proposed. In this article, we present an identity-based key agreement and encryption scheme for WSNs. This scheme is an elliptic curve cryptography type algorithm. First, we briefly review regarding identity-based encryption and decryption, particularly, the Boneh-Franklin algorithms. Then we describe a key agreement and encryption scheme on the basis of the Boneh-Franklin algorithms for WSNs. We discuss the efficiency and security of our scheme by comparing it with traditional public key technique and symmetric key technique.

Revisiting public-key cryptography for wireless sensor networks

The lack of a fixed infrastructure and the ad hoc nature of wireless sensor networks deployments suggest that the ability to encrypt and decrypt confidential data among arbitrary sensor nodes while enabling undisputed authentication of all parties will be a fundamental prerequisite for achieving security. To do this, nodes must be able to establish a secret key and know who their counterparts are. Thus, it becomes highly desirable to have a secure and efficient distribution mechanism that allows simple key generation for large-scale sensor networks while facilitating all the necessary authentications.
