Encrypted group communication method
Embodiments herein include, for example, a method, comprising: generating a shared symmetric key to begin a communication session among a group of users by a first user; distributing, by the first user, the generated shared symmetric key to each user in the group of users; communicating within the communication session among a group of users, where each user encrypts a message to the group of users to be distributed through the communication session using the generated shared symmetric key, and each user decrypts a message received from the communication session using the generated shared symmetric key.
1. A method, comprising:
generating a shared symmetric key to begin a communication session among a group of users by a first user, wherein the first user is the user initiating the group communication session and wherein the communication session is a long-lived session;
distributing, by the first user, the generated shared symmetric key to each user in the group of users;
communicating within the communication session among a group of users, wherein
each user encrypts a message to the group of users to be distributed through the communication session using the generated shared symmetric key, and
each user decrypts a message received from the communication session using the generated shared symmetric key, and
wherein each encrypted group communication comprises a short-lived secure communication session.
2. The method of claim 1 , further comprising changing users within the group of users to reform the communication session among a new group of users comprises:
generating a new shared symmetric key by the first user;
distributing, by the first user, the generated new shared symmetric key to each user in the new group of users.
3. The method of claim 2 further comprising:
communicating to the communication session among a new group of users, wherein each user encrypts a message to the new group of users to be distributed through the communication session using the generated new shared symmetric key, and
each user decrypts a message received from the communication session using the generated new shared symmetric key.
4. The method of claim 1 further comprising adding additional users to the communication session by distributing the generated shared symmetric key to the additional users.
