eSync, an Automotive Grade Over-the-Air Pipeline

​The Excelfore eSync System provides a secure path to exchange information between cloud-based servers and vehicles. This includes downstream data push such as over-the-air software and firmware updates, and upstream data pull such as device status, error codes, performance metrics and other diagnostic data.
eSync components in the cloud and in the vehicle create a secure bidirectional pipeline that reaches from the server not just to the head unit or vehicle gateway, but all the way to the end devices in the vehicle. Both downstream and upstream data is compressed and encrypted from origin to end point, providing end-to-end security with full data integrity. The eSync System is compatible with all popular automotive processors and operating systems.

WHAT WE PROVIDE

Features

The eSyncTM System has been developed to provide specific capabilities under a set of guiding principles.

• It is a single solution for data-push and data-pull. It can push data to the vehicle, for OTA updating of software and firmware. It also has the ability to pull data from the vehicle, for purposes of diagnosing and tracking vehicle status and performance.
• It reaches all the way to ECUs, sensors, and actuators, and is designed to reach any number of devices inside the vehicle.
• It provides end-to-end security. All OTA and diagnostic traffic is fully encrypted all the way from the Server to the Update Agent. The eSync System implements authentication in both directions. Authentication makes use of Public/Private Key (asymmetric) cryptographic technology.
• It is policy-driven. Policies for OTA updates are established by the OEM during creation of the OTA campaign. The policy engine architecture allows for customized policies to be created for an OEM’s particular needs.
• It scales to a virtually unlimited number of vehicles.
• It is modular. Boundaries of software components are well defined, and Excelfore makes the APIs available for these boundaries. The eSync System operates as a complete system, but each component can be licensed separately.

​
​Additional Features

• Fault-tolerant – The eSyncTM System is highly tolerant of faults or glitches during the update process.
• Adaptive Delta Compression Engine minimizes vehicle downtime cause by software updates.

eSync OTA pipeline for automotive

The eSyncTM System has components in the cloud and in the vehicle. In the cloud, there are eSync Servers for updates, diagnostics, and telematics. There is also a Campaign Manager cloud-based application. In the vehicle, there is one eSync Client and multiple eSync Agents for updates and diagnostics. Combined, these components provide a secure path for over-the-air (OTA) updates down to multiple end devices in vehicle, as well as diagnostics and telematics upstream to the cloud.

WP.29 Conformity

What is WP.29?

WP.29 was established on 6 June 1952 as the Working Party on the Construction of Vehicles, a subsidiary body of the Inland Transport Committee (ITC) of the United Nations Economic Commission for Europe (UNECE). In March 2000, WP.29 became the "World Forum for Harmonization of Vehicle Regulations (WP.29)". The objective of the WP.29 is to initiate and pursue actions aimed at the worldwide harmonization or development of technical regulations for vehicles. Providing uniform conditions for periodical technical inspections and strengthening economic relations worldwide, these regulations are aimed at:

• improving vehicle safety;
• protecting the environment;
• promoting energy efficiency and
• increasing anti-theft performance.
