Abstract: Apparatuses, systems, and techniques to perform a cryptographic operation using multiple iterations, wherein each iteration includes two or more stages operating in parallel on inputs derived from a common value, one of the stages computing real data and other stages computing dummy data.

Abstract: Approaches in accordance with various illustrative embodiments provide for the encryption of communications going into and out of a device, such as a chip or proprietary bus. The encryption can occur in a central Root-of-Trust (ROT), which can include agents for individual communication protocols to generate session keys used to encrypt communications for individual sessions, and the data can be sent to a crypto engine for the respective communication protocol. A key tunnel unit can be used to receive a wrapped session key over the public bus and then unwrap the key in hardware, then able to then transmit the unwrapped session key to the corresponding crypto engine without exposing the session key to software executing on the device outside the RoT. The receiving inline crypto engine can then use that session key to encrypt session data to be transmitted to a separate device or destination.
