Abstract: The present embodiments relate to establishing secure data communication using an Elliptic-curve Diffie-Hellman ephemeral (ECDHE) key agreement procedure. Devices in a network environment can utilize a key agreement procedure to establish secure communication between multiple application layers in a micro service architecture. Particularly, a tunnel can be established between a mobile device and an encryption service by transmitting key information between the mobile device and the encryption service. This can allow for encryption keys to only be accurately generated by the mobile device and encryption service. Accordingly, intermediary nodes may be unable to decrypt the data, allowing for safe and secure transport of sensitive data.

The private key is kept secret and is known to an originator and/or publisher of a media file. The public key is added to the media file and is used to validate integrity of the media file, that is, that content of the media file (e.g., portion(s), frame(s)) has not been altered since publication of the media file. By validating integrity of the media file, strong proof that the media file came from an owner of the keypair (e.g., had possession of the private key) can be obtained, for example, resolving issues of trust and/or authenticity common in altered content. In some embodiments, information regarding an origin of the content can further be determined.
