Custom Cryptography Services

IoT is becoming more and more part of our lives, touching a lot of areas from simple, smart devices automating our homes to sophisticated systems like autonomous driving with highly critical safety constraints. As all these devices connected to the Internet host sensitive information, start to exchange it, decide many times and take action based on these inputs, securing them effectively against malicious hackers shall be considered by design.

Being an active player for many years in embedded software development, Tremend can confidently claim a strong background in dealing with all these more and more sophisticated security challenges. The SW development process in Tremend starts from the initial security risk assessment, it goes through the security-aware design phase and ensures high-quality, secure coding standards compliance.

Telemetry System for Motorcycles

Tremend offered consultancy services to a motorcycle OEM for designing and developing an offroad motorcycle telemetry system. A critical part of the elaborated solution was to ensure ISO21434 compliance consisting of activities like:

  • Security risks assessment taking into account the specificity of an Internet-connected telemetry system with access to internal vehicle interfaces
  • Design an intrusion detection and prevention solution that detects new possible vulnerabilities and allows the deployment of countermeasures in a timely manner.
  • Design an Over The Air (OTA)update solution for both backend and client with an intrinsic fallback path ensures the vehicle returns to a running state even in the case of a major software update failure.

Bluetooth Smart Lighting

Our experts offered consultancy for supporting message signature and authentication based on AES-256 and ECDH algorithms.

Autosar MCAL Crypto module

A team from Tremend was involved in designing and implementing several Autosar BSW Crypto modules for a hardware provider on top of their security hardware accelerators. Below are some key points defining this collaboration:

  • Identify typical security use-cases in the Automotive industry in order to map the available security HW accelerator features to the Autosar Crypto interface in an effective way
  • Design and implement solutions for minimizing sensitive data exposure in SW-only security implementation.
  • Seamless integration in the customer’s organization by assimilating and following their Automotive SPICE processes and methodologies as a good base for further ISO21434 compliance.

Why Tremend?

During more than 16 years of delivering consultancy in software development, Tremend was involved in many diverse cross-platform projects, many of them addressing cybersecurity challenges in different industries like automotive, telecom, financial, retail, and public sector. And the embedded software components were many times part of these systems.

This legitimates Tremend’s confidence in our capability to offer security solutions in this growing interconnected world.
