Abstract: 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.

Abstract: Embodiments disclosed herein provide a method that includes receiving, at a client-side web browser, a minimal bootstrap payload from an application server; storing, by a client-side processor, the minimal bootstrap payload in a client-side local cache, where the locally cached minimal bootstrap payload is executed by the client-side processor before executing an application from the application server; the minimal bootstrap payload includes at least one public key and at least one Uniform Resource Location (URL) address of an application code payload.

Abstract: Embodiments herein include, for example, a method that includes signing onto an secure communications system; sending a communication message; and transmitting every messages to all devices in a device group, before displaying any message sent or received.

Abstract: Embodiments herein provide, for example, a method that includes generating a deniability key; downloading an encrypted blob from a server, where the encrypted blob includes a server-stored symmetric key and is encrypted with a user password; and decrypted the encrypted blob with a locally-stored symmetric key and the user password, where the sever-stored symmetric key: encrypts a message before transmitting the message to an intended recipient, and decrypts a received message, where the deniability key encrypts a deniable message before transmitting the message to an intended recipient, and where the message and the deniable message are transmitted in a random order to the intended recipient.

Abstract: Embodiments herein provide, for example, a method that includes generating a shared symmetric key to exchange authentication information among a communications group; distributing the generated shared symmetric key to each communicating party in the communications group; exchanging authentication information among members of the communications group, where each communicating party: encrypts the authentication information using the generated shared symmetric key and sends the encrypted authentication information to other members of the communications group, and receives encrypted authentication information from another communicating party in the communications groups and decrypts the received encrypted authentication information using the generated shared symmetric key.
