The use of smart embedded device has been growing rapidly recently because of the miniaturization of sensors and platforms. A resource-efficient Public Key Cryptography (PKC) is very desirable for the resource-constrained embedded system. Whereas most public key security protocols requires both public and private keys to be generated together, Identity Based Encryption (IBE), a public key cryptography protocol, allows the public key to be generated from an arbitrary string. IBE has been actively researched and deployed, but conventional IBE primitives are still computationally demanding and may not be suitable for all embedded system. Simplified version of the identity based encryption is available and satisfies the tight budget of the embedded platform. In this thesis, we describe the implementation of lightweight IBE based on elliptic curve in resource-constrained embedded sensor nodes. We also compare and contrast its performance with the conventional pairing-based approach.
