Efficient ID-based Broadcast Threshold Decryption in Ad Hoc Network
Zhenchuan Chai, Zhenfu Cao, Yuan Hua Zhou · 2006
In this paper, we construct an efficient ID-based broadcast threshold decryption scheme in mobile ad hoc network. Our scheme allows a sending node to efficiently broadcast an encrypted message to many dynamic groups in such a way that only the groups meeting the minimal size requirement (number of nodes that is within the range of the group) can read the message. Moreover, we analyze the security and discuss how to improve the security of the scheme. Finally, we evaluate our scheme's performance
