Overview

The Helion Fast Hash core family implements the NIST approved SHA-1, SHA-256, SHA-384 and SHA-512 secure hash algorithms to FIPS 180-3 and the legacy MD5 hash algorithm to RFC 1321. These are high performance cores that are available in single or dual algorithm versions and have been designed specifically for use in ASIC.

The hash algorithms take as input a message of arbitrary length, process the message as a series of 512 or 1024 bit blocks, and produce as output a compressed representation of the message data in the form of a message digest, the length of which varies with hash algorithm. Applications for the hashing cores include implementations of the standard Keyed-Hash Message Authentication Code (HMAC) described in FIPS 198-1. They are commonly used in the IPsec and TLS/SSL protocols, as well as Digital Signature applications, where a hash function is required to ensure both data integrity and origin authentication.

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.
