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, 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 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 downloading a symmetrically encrypted data block from a server, where the encrypted data block comprises a server-stored secondary password; decrypting the encrypted data block with a shared-symmetric key; signing onto at least one of a server or service using the server-stored secondary password; generating a secondary password, where the generated secondary password is different than the server-stored secondary password; and overwriting the server-stored secondary password with the generated secondary password.

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: Embodiment herein provide, for example, a method, comprising: downloading an encrypted data block from a server, where the encrypted data block includes a server-stored symmetric key; and decrypted the encrypted data block with a locally-stored symmetric key, where the sever-stored symmetric key: encrypts a message before transmitting a message to it's intended recipient; and decrypts a received message.

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.

Abstract: Embodiments herein provide, for example, method, comprising: requesting, by a first user on a first device, to open a channel of communication to a second user on a second device; confirming the first user's identity and the second user's identity through a second channel that is separate from the communication channel; and communicating through the communication channel after each user has validated the other party's identification through the second channel.

Abstract: Embodiments herein provide, for example, a method that includes, comprising: sending a request, by a first user on a first device, to a server, the request comprising requesting the server open an ephemeral communication session with a second user on a second device; allocating resources, by the server, to begin the ephemeral communication session between the first user and the second user; generating a unique ephemeral communication session identifier by the server and transmitting the unique ephemeral communication session identifier to the first user; transmitting, by the first user, the unique ephemeral communication session identifier to the second user using a second communication channel; connecting, by the second user, to the first user through the ephemeral communication session using the unique ephemeral communication session identifier; and connecting, by the first user, to the second user through the ephemeral communication session using the unique ephemeral communication session identifier.
