Overview

The HMAC-SHA256 cryptographic accelerator function is used to securely generate and verify message authentication codes. Message authentication is increasingly required by corporations, government organisations, and individuals to secure communications between sender and receiver. The HMAC – SHA256 authentication function is especially suited for cybersecurity, defense, and aerospace applications, and can be added to existing products, or designed into prototypes. Contact us for more information, or to discuss source code and netlist licensing options for Intel and AMD FPGAs and ASICs.

The all-RTL solution provides a fast and secure way to calculate a SHA256 hash for any message of any length. When combined with a secret key, it can also construct a HMAC keyed-hash message authentication code, which can be used to protect messages that are sent, and verify those that are received. The HMAC-SHA256 accelerator accepts multiple independent streaming messages/channels and support any number of arbitrary length messages. Number of channels is limited only by the memory resources provided, embedded Block RAM or external DDR. Typical use cases include highly secure RTL solutions where a CPU is unable to meet the required throughput and security performance.

The Challenge of Automotive Hardware Security Deployment

A complete reinvention of the automotive industry is currently underway. Autonomous driving, connected vehicles, and the electrification of the powertrain all represent a once-in-a-generation shift in the manufacturing process.

Embracing a More Secure Era with TLS 1.3

TLS 1.3 offers attractive speed and security improvement benefits that are hard to ignore. The handshake phase was sped up by removing one or more roundtrips (back and forth messaging between client and server) in TLS 1.3 – with “or more” meaning that for certain cases, roundtrips can be entirely eliminated (0-RTT).

Standardized PUF-based Solution for Device eID

In this column, after a background introduction, we will first discuss IEEE 802.1AR standard on secure device identity. Next, we’ll assert PUF is an enabling solution for the device eID. Third, we will discuss PUF related international standards. Fourth, we will present a short tutorial on PUFiot. Fifth, we will assert that PUFiot is an ideal Device eID with wide applications. Finally, we will draw a conclusion on the future trend of Device eID development.

Implementing Ultra Low Latency Data Center Services with Programmable Logic

Data centers require many low-level network services to implement high-level applications. Key-Value Store (KVS) is a critical service that associates values with keys and allows machines to share these associations over a network. Most existing KVS systems run in software and scale out by running parallel processes on multiple microprocessor cores to increase throughput.

Security in vehicular systems

With the advent of IoT and increasingly interconnected and autonomous nature of a vehicle’s control modules, there has been an exponential increase in V2V, V2X and inter vehicular communications. This in turn increases the attack surface for hackers which demands state-of-art security features in modern automotive microcontrollers, moreover safety and security go hand in hand.
