7 terms

public key infrastructure technical

"a leader in semiconductors, Public Key Infrastructure (PKI), and post-quantum"

A public key infrastructure (PKI) is the system of digital keys, certificates and trusted procedures that proves who is on the other end of an electronic interaction and encrypts the data they exchange. Think of it as a verified digital mailroom and set of padlocks: one key is shared publicly to lock messages and a matching secret key unlocks them, which helps prevent fraud, supports secure transactions, regulatory compliance and preserves investor trust in a company’s digital operations.

pki technical

"a leader in semiconductors, Public Key Infrastructure (PKI), and post-quantum"

PKI (Public Key Infrastructure) is a system that creates and manages digital “keys” and electronic certificates to prove identities and secure online communications, like a bank vault and ID card for data. For investors, PKI matters because it helps prevent fraud, ensures that financial documents and trading instructions are genuine, and reduces regulatory and operational risk tied to hacked accounts or tampered disclosures.

post-quantum cryptography medical

"and post-quantum cryptography (PQC) hardware and software solutions, today"

Post-quantum cryptography is a set of new methods for scrambling data so it stays secure even if powerful quantum computers exist; think of replacing today’s locks with designs that a future high‑speed lockpicker cannot open. For investors, it matters because companies must upgrade systems, meet regulations, and protect customer and trade data—creating costs, competitive advantages, or legal and reputational risks depending on how quickly and effectively they adopt these new security standards.

trusted platform module technical

"QS7001 secure System-on-Chip (SoC) and QVault Trusted Platform Module (TPM)"

A trusted platform module (TPM) is a small, dedicated hardware chip in a computer or device that securely stores digital keys, passwords and security measurements and performs protected cryptographic tasks. Think of it as a tamper-resistant safe or fingerprint lock for a machine’s identity and startup process. For investors, TPMs matter because they reduce the risk of hacks, help companies meet security rules and customer trust standards, and can affect product value, liability and compliance costs.

system-on-chip technical

"SEALSQ's QS7001 secure System-on-Chip (SoC) and QVault Trusted Platform"

A system-on-chip (SoC) is a single silicon chip that combines the main computing processor, memory, and key interfaces (like graphics, wireless radios or input/output controllers) that a device needs to run. Think of it as a compact, all-in-one engine that replaces many separate parts, saving space, power and cost. For investors, SoC design and production influence product performance, margins and supply risk, and can be a major competitive advantage in electronics markets.

hardware roots of trust technical

"integrate hardware roots of trust with PQC capabilities, while the INeS PKI"

A hardware root of trust is a small, dedicated chip or hardware function that anchors a device’s security by holding secret keys and performing basic checks that other software relies on. Think of it as a locked vault or foundation piece that proves a device’s identity and ensures software hasn’t been tampered with. For investors, strong hardware roots of trust lower the risk of costly breaches, enable secure services and regulatory compliance, and can be a competitive advantage for products that handle sensitive data.

iot technical

"interoperability in large-scale IoT deployments for smart utilities. SEALSQ's"

The Internet of Things (IoT) describes a network of everyday devices—such as appliances, vehicles, and equipment—that are connected to the internet and can share data automatically. For investors, IoT represents a growing trend that can drive efficiency and innovation across many industries, potentially creating new opportunities for growth and value. Its expansion influences how companies operate and compete in a digitally connected world.

Geneva, Switzerland, March 26, 2026 (GLOBE NEWSWIRE) --

SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a leader in semiconductors, Public Key Infrastructure (PKI), and post-quantum cryptography (PQC) hardware and software solutions, today announced its readiness to support the Wi-SUN Alliance and its members in addressing the emerging challenges of quantum computing threats to smart energy infrastructure. SEALSQ's advanced post-quantum (PQ) chips and comprehensive PKI services position the Company to provide expert guidance and solutions for developing transition roadmaps toward full quantum resilience in smart meter ecosystems.

As quantum computing advances pose risks such as "harvest now, decrypt later" attacks to current cryptographic systems, the smart energy sector, including Wi-SUN-compliant networks, requires proactive preparation for hybrid and post-quantum cryptographic migrations. While Wi-SUN protocols already incorporate strong security features like 256-bit AES for data protection, SEALSQ stands prepared to collaborate with the Alliance and its members to enhance these frameworks with NIST-approved PQC algorithms, ensuring long-term compliance and interoperability in large-scale IoT deployments for smart utilities.

SEALSQ's QS7001 secure System-on-Chip (SoC) and QVault Trusted Platform Module (TPM) integrate hardware roots of trust with PQC capabilities, while the INeS PKI platform delivers scalable device identity management, secure provisioning, certificate lifecycle handling, and support for cryptographic agility, critical tools for constructing phased transition roadmaps that minimize disruption while achieving quantum resilience.

SEALSQ is already actively engaged with Wi-SUN Alliance members, including through its established partnership with Landis+Gyr, a leading smart metering provider. This collaboration utilizes SEALSQ's INeS PKI and secure elements to strengthen network security and meet regulatory requirements for advanced metering infrastructure (AMI).

"Quantum threats demand forward-thinking collaboration across standards bodies and industry leaders," said Carlos Moreira, CEO of SEALSQ. "SEALSQ is fully prepared to bring our PQ chip expertise and PKI leadership to the Wi-SUN Alliance, helping members navigate the transition to quantum-resilient systems with practical, hardware-anchored solutions and customized roadmaps that safeguard smart meter ecosystems for the future."
Phil Beecher, President and CEO of the Wi-SUN Alliance, emphasizing the organization's attention to this critical topic, noted, "We're looking at the post-quantum topic carefully and are glad to have members like SEALSQ contributing their expertise to help advance quantum-resilient capabilities across our ecosystem."

SEALSQ will participate actively in the Wi-SUN Open House 2026 on March 27, 2026, at Ochanomizu Sola City Hall West in Tokyo. This important full-day event focuses on the latest advancements in Wi-SUN FAN and HAN technologies, massive IoT, and smart utility networks. SEALSQ looks forward to engaging with Alliance members and stakeholders to discuss opportunities for enhancing Wi-SUN protocols and building quantum-resilient compliance strategies.

Following the Wi-SUN Open House, SEALSQ will be inviting a selection of customers and local partners to celebrate SEALSQ's partnership with the BWT Alpine Formula 1 Racing Team during the Suzuka Japanese Grand Prix weekend (March 27-29, 2026). This private gathering will highlight the innovative application of quantum-secure technologies across high-performance sectors, from smart energy infrastructure to elite motorsport.
