Abstract: A rover or semi-autonomous or autonomous vehicle may use an image classifier to determine a terrain class of regions of an image of the terrain ahead of the rover or vehicle. The regions of the images are used to estimate the slope of the terrain for the different regions. The terrain class and slope are used to predict an amount of slip the rover will experience when traversing the terrain of the different regions. A heuristic mapping for the terrain class may be applied to the predicted slip amount to determine a hazard level for the rover or vehicle traversing the terrain.

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.
