How carmakers and Tier-1 suppliers can secure connected cars

ELE Times - Fri, 02/17/2023 - 10:46

Author: STMicroelectronics

Connected cars provide opportunities for car makers and Tier-1 suppliers to introduce new functionalities and services such as infotainment, digital key systems, authentication, and vehicle-to-everything (V2X) communication. While these new possibilities promise many benefits, cybersecurity experts have voiced well-founded concerns over how this connectivity is secured. Let’s discover how we can ensure the highest level of security in connected cars, in a timely and cost-effective manner.

Hardware secure MCUs: the safest road to security

Among the different strategies available to tighten security, hardware systems offer greater protection against tampering and other malicious attacks than any software-based approach. EAL6+ Common Criteria certified, ST’s secure hardware element offers the highest level of security currently available. Named ST33K-A, the product provides authentication, confidentiality, and integrity services to protect car manufacturers and Tier-1 suppliers against cloning, counterfeiting, malware injection and unauthorized production.

ST33K-A was specifically developed for the automotive industry. Designed to protect any kind of device from unauthorized access, this tamper-proof MCU can store confidential and cryptographic data, protect credentials and run secure, unique authentication and identification services. More specifically, ST33K-A securely generates and stores encryption keys in a Root of Trust (RoT) platform to encrypt and decrypt data “on demand”. These tasks can be performed effectively in harsh environments, from –40 °C up to 105 °C. In terms of performance, the chip incorporates the most recent generation of Arm® processors.

Easy Lego-like modular developments

ST’s hardware secure MCU has more to offer than just security. It can host and run a wide range of in-cabin applications, such as Qi charging pads, digital car keys and ‘plug and go’ platforms. To create and secure these connected services in a timely manner, ST has developed an easy-to-use modular approach. Developers can use the ST33K-A secure element as a strong security hardware foundation. Depending on their targeted applications, they can add STSAFE-V, a secure system solution for vehicles, with either a STSAFE-VJ multi-SoC solution based on Java Card or a STSAFE-TPM dedicated solution. This agile development process is the preferred solution of thousands of OEMs. More than 1.5 billion units of ST33 have been sold and customized so far.

ST provides end-to-end confidentiality. ST33K-A units are produced using certified manufacturing processes, through a trusted supply chain with pre-provisioned secrets and certificates. Sensitive customer data is handled in a highly confidential environment. Developers receive a set of software libraries and drivers to ensure their secure and seamless integration into the final device. If necessary, ST can also develop tailored innovative solutions that meet specific customer needs.

Affordable security access points

The automotive industry is moving to deliver the right level of security. But change doesn’t happen overnight. While a secure element might be the only viable route to security, concerns about the cost of implementing such a secure element into every single device may arise. ST’s R&D team is committed to helping carmakers and Tier-1 suppliers to gradually upgrade their architecture in a cost-effective way. As a leader in integrated solutions, ST R&D experts can create access points, with one single secure element addressing various applications. More information is available on our website.

Make sure you aren’t ignoring threats. Build new competitive infotainment services that keep hackers out with ST33K-A and STSAFE-V.

Ascon algorithms finalized for lightweight cryptography

EDN Network - Fri, 02/17/2023 - 07:41

The National Institute of Standards and Technology (NIST) has selected a group of cryptographic algorithms to secure the Internet of Things (IoT) devices and the related tiny sensors and actuators. Ascon, a group of cryptographic algorithms, will also serve other miniature devices like medical gadgets, stress detectors inside roads and bridges, and keyless vehicle entry fobs.

NIST will publish the “lightweight cryptography” standard later this year. It’ll be targeted at tiny devices that have limited resources and thus demand a compact security implementation. “The Ascon algorithms for lightweight cryptography will cover devices with resource constraints,” said NIST computer scientist Kerry McKay.

Several years ago, NIST announced a development program to determine the strongest and most efficient lightweight algorithms, first communicating with industry and other organizations to understand the needs. In 2018, it requested potential solutions from the cryptography community and received 57 submissions. Next, McKay and mathematician Meltem Sönmez Turan carried out a multi-round public review process and selected 10 finalists.

Finally, Ascon became the winner for its algorithm’s performance and flexibility in terms of speed, size, and energy use. Ascon—developed in 2014 by a team of cryptographers from Graz University of Technology, Infineon Technologies, Lamarr Security Research, and Radboud University—is currently available in seven variants.

Ascon’s lightweight cryptography variants

According to McKay, Ascon’s two variants or tasks are among the most important in lightweight cryptography: authenticated encryption with associated data (AEAD) and hashing. AEAD—besides protecting the the confidentiality of a message—allows additional information like the header of a message or a device’s IP address to be included without being encrypted. In lightweight cryptography, it can be used in vehicle-to-vehicle communications. It can also help prevent the counterfeiting of messages exchanged with the RFID tags that often help track packages in warehouses.

On the other hand, hashing creates a short digital fingerprint of a message that enables a recipient to determine whether the message has changed. It can be used to check whether a software update is appropriate or has been downloaded correctly.

Here, it’s worth mentioning that the the most efficient NIST-approved technique for AEAD is the Advanced Encryption Standard (AES), while SHA-256 is widely used for hashing. However, as McKay clarified, the goal of this project is not to replace AES or hash standards. “NIST still recommends their use on devices that don’t have the resource constraints that these new algorithms address.”

McKay added that the new algorithms are also not intended to be used for post-quantum encryption, another current concern of the cryptography community that NIST is addressing. “Post-quantum encryption is primarily important for long-term secrets that need to be protected for years,” she said. “In contrast, lightweight cryptography is generally important for more ephemeral secrets.”
