Systems and methods for encrypted communication in a secure network

Non-transitory computer storage that stores executable program instructions that, when executed by one or more computing devices, cause the one or more computing devices to perform operations comprising:

• receiving an encrypted first message from a device, wherein the first message comprises a username and a password and the first message is encrypted using a first public key;
• decrypting the first message using a first private key;
• authenticating the username and the password;
• generating a session identifier;
• retrieving an address and a second public key of a communication server;
• generating a third key pair comprising third public and private keys;
• generating a fourth key pair comprising fourth public and private keys;
• sending a second message to the communication server, wherein the second message comprises the fourth public key, the username and the session identifier;
• encrypting a third message, using the third public key, wherein the third message comprises the session identifier, the address of the communication server, the second public key, and the fourth private key;
• sending a fourth message to the device, wherein the fourth message comprises the encrypted third message and the third private key;
• decrypting the third message, using the third private key;
• encrypting a fifth message, using the second public key, wherein the fifth message comprises the session identifier and the username;
• decrypting the fifth message, using the second private key;
• authenticating the session identifier and the username;
• encrypting communications from the device to the communication server using the second public key, decrypting the communications from the device to the communication server using the second private key;
• and
• encrypting communications from the communication server to the device using the fourth public key, decrypting the communications from the communication server to the device using the fourth private key.
