METHOD AND SYSTEM FOR NON-INTERACTIVE, DYNAMIC AND SECURE GROUP COMMUNICATION

摘要

A method and system is provided for non-interactive secure group communication among a dynamic group of nodes. Method of the present invention includes enabling a node to create a group key in run time using its secret share, a random number, and network identities of recipient nodes, wherein the secret share is generated based on elliptic curve cryptography. Method and system of the present disclosure further include encrypting/decrypting a message using the group key. Method and system of the present disclosure further provides for addition and deletion of a node from a group and provides full forward and back secrecy.
