Method for securely communicating data between members of a group of mobile devices using a wireless channel |
摘要 |
<p>A method securely communicates data between members of a group of mobile devices using a wireless channel. The members include a group leader. Each member is associated with a physical token. Each member and associated token stores a binding key. Each member also stores an identification. A session key is stored by the group leader. Each token generates a member key, which is encrypted with the binding key and transmitted to the member where it is decrypted and stored. The session key is distributed securely to each member. Each member key is securely passed to the group leader. Then, data to be communicated between the group leader and a particular member can be encrypted using the associated member key of the particular member and the session key.</p> |
