Social integration is an essential part of the life of every human being, but for people with disabilities, there are many situations in which it is still very low. For instance, in sports and outdoor gaming, there is a barrier between players with and without disabilities. Individuals with disabilities play sports almost exclusively with disabled...

This paper presents a System-on-Chip (SoC) implementation of a cryptographic hardware accelerator supporting multiple AES based block cypher modes, including the more advanced CMAC, CCM, GCM and XTS modes. Furthermore, the proposed design implements in hardware advanced features for AES key secure storage. A flexible interface allows the communicat...

This article presents a cryptographic hardware (HW) accelerator supporting multiple advanced encryption standard (AES)-based block cipher modes, including the more advanced cipher-based MAC (CMAC), counter with CBC-MAC (CCM), Galois counter mode (GCM), and XOR-encrypt-XOR-based tweaked-codebook mode with ciphertext stealing (XTS) modes. The propose...

Cybersecurity is a critical issue for Real-Time IoT applications since high performance and low latencies are required, along with security requirements to protect the large number of attack surfaces to which IoT devices are exposed. Elliptic Curve Cryptography (ECC) is largely adopted in an IoT context to provide security services such as key-exch...

Random numbers are widely employed in cryptography and security applications. If the generation process is weak, the whole chain of security can be compromised: these weaknesses could be exploited by an attacker to retrieve the information, breaking even the most robust implementation of a cipher. Due to their intrinsic close relationship with anal...

This paper proposes the architecture of the hash accelerator, developed in the framework of the European Processor Initiative. The proposed circuit supports all the SHA2 and SHA-3 operative modes and is to be one of the hardware cryptographic accelerators within the crypto-tile of the European Processor Initiative. The accelerator has been verified...

In the context of growing the adoption of advanced sensors and systems for active vehicle safety and driver assistance, an increasingly important issue is the security of the information exchanged between the different sub-systems of the vehicle. Random number generation is crucial in modern encryption and security applications as it is a critical...

Deafblind people face remarkable challenges in communicating, because of their severe disability. The only way to interact with other people is the usage of the tactile sign language, which consists in understanding the sign language putting their hands on the signer’s hands. But this approach works only when the signers are in the same place. The...

Random numbers are widely employed in cryptography and security applications, and they represent one of the main aspects to take care of along a security chain. They are employed for creation of encryption keys, and if generation process is weak, the whole chain can be compromised: weaknesses could be exploited to retrieve the key, thus breaking ev...

Modern networks have critical security needs and a suitable level of protection and performance is usually achieved with the use of dedicated hardware cryptographic cores. Although the Advanced Encryption Standard (AES) is considered the best approach when symmetric cryptography is required, one of its main weaknesses lies in its measurable power c...

The work analyses the cybersecurity weakness in state-of-art automotive in-vehicle networks and discusses possible countermeasures at architecture level. Due to stringent real-time constraints (throughput and latency) of fail-safe automotive applications, hardware accelerators are needed. A hardware accelerator design for AES (Advanced Encryption S...

Addressing Man-In-The-Middle threat in automotive wireless links Luca Crocetti, Luca Baldanzi and Luca Fanucci Department of Information Engineering, University of Pisa Connected cars is one of the hot topic in the automotive field because it is a fundamental step along the roadmap to autonomous driving. Wireless communication links such as Wi-Fi...
