Abstract
While IoT becomes more and more popular, security becomes an important issue when IoT deployment. Considering there are lot of mobile device, it is frequent for member joining and leaving. Therefore, traditional key agreement schemes are not suitable for dynamic IoT environments. In this paper, we propose a dynamic key management scheme to avoid key update overhead when membership changing.

Notes
- 1.
In Blom’s work, it is not required to use a Vandermonde matrix. Here we use the Vandermonde matrix for convenience and the storage issue.
- 2.
Of course, users can prepare a larger pool for new coming nodes.
