摘要
A method and system for establishing secure communications between endpoints includes transmitting a first message including a token having one or more entries each corresponding to a community of interest associated with a user of the first endpoint and including an encryption key and a validation key associated with the first endpoint. The method includes receiving a second message including a second authorization token including one or more entries, each entry corresponding to a community of interest associated with a second user and including an encryption key and a validation key associated with the second endpoint. The method includes, for each community of interest associated with both users, decrypting an associated entry in the second authorization token to obtain the encryption key and validation key associated with the second endpoint. The method also includes generating a shared secret based on the key pair, transmitting a third message including the created key pair to the second endpoint, and initializing tunnel using the shared secret to derive encryption keys used for IPsec-secured communications between the endpoints.
