We design a secure group key management scheme and multi-layer group key management scheme using polynomial interpolation method. The proposed scheme follows a new approach for key computation. We propose new key structures for managing the group keys for both the secure group and multilayer schemes. We prove the security of the proposed schemes, and the schemes are efficient in terms of rekeying cost compared with few schemes available in the literature.
