Interaction Key Generation Schemes
Summary :
This paper proposes a new concept of Interaction key. An interaction key is a group public key that corresponds to a shared key shared by multiple users, and it has a new feature that an interaction key generator can verify the following: the shared key has been generated now, and the shared key has not existed before. In other words, the multiple users can prove them to the key generator. This feature is different from Time-stamp technology proves that a message existed at a point in time. Here, the key generator is a third party that can observe communications of the multiple users. Present technology only allows a group member or a privileged entity to generate a group public key. We are not presently aware of a technology where a third party can generate the group public key as above. The interaction key technology is useful both for generating public key certificates and for message certification. In a certificate generation, a certificate authority can issue a public key certificate with the shared key (i.e. secret key) to be used by the multiple users. In a message certification, the users can prove the signed message has not existed before, since the message is signed by the shared key corresponds to the interaction key.
