Overview

The SHA256 IP core from Alma Technologies is a high performance implementation of the SHA-256 Message Digest algorithm, a one-way hash function, compliant with FIPS 180-2.

The core is composed of two main units, the SHA256 Engine and the Padding Unit as shown in the block diagram. The SHA256 Engine applies the SHA256 loops on a single 512-bit message block, while the Padding Unit splits the input message into 512-bit blocks and performs the message padding on the last block of the message.

The processing of one 512-bit block is performed in 66 clock cycles and the bit-rate achieved is 7.75Mbps / MHz on the input of the SHA256 core.

The SHA256 core is equipped with easy to use fully stallable interfaces both for input and output. These are designed to permit the user's application to stop the data stream from the core when it is not able to receive data or to stop the input stream towards the core according to data arrival rate.

Key features

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.
