Abstract: Aspects of the invention are directed to techniques for mutual authentication between a passenger that has requested a transportation service and a dispatched vehicle for providing the requested transportation service. A user device associated with the passenger verifies the dispatched vehicle using a vehicle access token generated by a transportation service platform and sends a secret key to the dispatched vehicle. The dispatched vehicle uses the secret key to recover passenger biometric information from a passenger secret received from the user device through the transportation service platform, captures passenger biometric information on-site, and compares the recovered passenger biometric information and the passenger biometric information collected on-site to verify the passenger.

Abstract: A process for operating a thermal or catalytic cracking unit is described. The process entails generating a product that includes cracked hydrocarbon vapor and solid coke-particles from a heavy hydrocarbon input. The product is communicated towards a fractionator and a quench liquid is introduced into the product for creating a two-phase flow of cracked hydrocarbon vapor and the quench liquid with solid coke-particles entrained in the quench liquid. The two-phase flow is introduced into the fractionator and the cracked hydrocarbon vapor are separated from the quench liquid and the solid coke-particles entrained therein by gravity separation. The two-phase flow can reduce or remove the requirement of a wash zone within the fractionator. A recirculation loop is included in a wash-zone circulation system. The recirculation loop bypasses one or more spray headers of the wash zone and returns to a first end of the wash-zone circulation system.

Abstract: Disclosed are techniques for mutual authentication between a passenger that has requested a transportation service and a dispatched vehicle for providing the requested transportation service. A user device associated with the passenger verifies the dispatched vehicle using a vehicle access token generated by a transportation service platform and sends a secret key to the dispatched vehicle. The dispatched vehicle uses the secret key to recover passenger biometric information from a passenger secret received from the user device through the transportation service platform, captures passenger biometric information on-site, and compares the recovered passenger biometric information and the passenger biometric information collected on-site to verify the passenger.

Abstract: Disclosed are techniques for securing electronic control units (ECUs) in a vehicle. A security platform for a vehicle includes a key distribution center (KDC) for the vehicle. The KDC is configured to verify that a digital certificate associated with a first electronic control unit (ECU) on the vehicle is a valid certificate, where the digital certificate indicates a first security level of the first ECU. The KDC is configured to generate, based on the first security level of the first ECU, one or more security keys for secure communication between the first ECU and a set of ECUs on the vehicle, and provision the one or more security keys to the first ECU and the set of ECUs. In some embodiments, the KDC uses the provisioned keys to authenticate each ECU when the vehicle is powered up.
