Securing IoT Devices With Lightweight Cryptography


The National Institute of Standards and Technology (NIST) recently announced the selection of a new family of cryptographic algorithms called ASCON, which have been developed for lightweight cryptography applications. In this blog, we will explore what lightweight cryptography is and why it is worth considering for specific Internet of Things (IoT) use cases. In summary, lightweight cryptogr... » read more

Security Highlight: Ascon


The contest for standardization of a lightweight crypto (LWC) algorithm has just finished. US standards body NIST selected Ascon as the winner. Ascon is an algorithm proposed by an international team of scientists that delivers strong performance and security at a low cost. How does that work? Lightweight crypto is symmetric encryption technology, that runs well on constrained systems, lik... » read more

Security Highlight: Exploiting Persistent Faults In Crypto


At the most recent CHES workshop, Hossein Hadipour of the Graz University of Technology presented an important step forward in exploiting persistent faults in crypto. Differential Fault Analysis (DFA) is a well-known attack class that can lead to the compromise of a secret key when faults are injected during the execution of a cryptographic implementation. However, injecting transient fault... » read more

Countering The Threat From Quantum Computers


Quantum computers hold much promise for the future, yet their computing power poses a significant threat to current security methods such as public key cryptography. In this white paper, Infineon will examine this issue in detail, propose an approach for future security based on TPMs and discuss current TPM technology. The reader can expect to gain a good appreciation of the security issues sur... » read more

Hardware Accelerator For Fully Homomorphic Encryption


A technical paper titled "CraterLake: A Hardware Accelerator for Efficient Unbounded Computation on Encrypted Data" was published by researchers at MIT, IBM TJ Watson, SRI International, and University of Michigan. "We present CraterLake, the first FHE accelerator that enables FHE programs of unbounded size (i.e., unbounded multiplicative depth). Such computations require very large cipherte... » read more

Memory-Based Cyberattacks Become More Complex, Difficult To Detect


Memories are becoming entry points for cyber attacks, raising concerns about system-level security because memories are nearly ubiquitous in electronics and breaches are difficult to detect. There is no end in sight with hackers taking aim at almost every consumer, industrial, and commercial segment, and a growing number of those devices connected to the internet and to each other. According... » read more

Security Highlight: Honda Rolling-PWN Attack


The attack known as Rolling-PWN (CVE-2021-46145) [1] is the latest of a recent series of security issues affecting the car’s immobilizers and RKEs (Remote Keyless Entry, also known as the keyfob or remote control). Over the past years, we have seen how security researchers identified attacks that could open and even start cars from vendors like Tesla [2], Hyundai-Kia [3], VAG (Volkswagen, ... » read more

Implementing Cryptographic Algorithms for the RISC-V Instruction Set Architecture in Two Cases


This new technical paper titled "Symmetric Cryptography on RISC-V: Performance Evaluation of Standardized Algorithms" was published by researchers at Intel, North Arizona University and Google, with partial funding from U.S. Air Force Research Laboratory. Abstract "The ever-increasing need for securing computing systems using cryptographic algorithms is spurring interest in the efficient i... » read more

Hertzbleed: Prime Time For Power Side Channel Countermeasures Or Novelty Attack?


Hertzbleed is a new side-channel attack that turns a power side channel into a timing side channel. That timing side channel may be exploitable even if the algorithm runs in a constant number of clock cycles. The novel observation is that the duration of a clock cycle can vary depending on the data processed on a CPU that uses dynamic frequency scaling. This allows a remote attacker to extract... » read more

Maximize Memory Security Of HPC SoCs With Efficient Crypto IP


Data that is created and transferred between billions of devices and the cloud is growing exponentially. More and more devices are entering the market, the cloud is expanding to the network edge and new applications are emerging. These factors are drivers for technological advances in high-performance computing (HPC), reshaping system-on-chip (SoC) designs to address the need for more accelerat... » read more
