Key Terms

private investment in public equity, ground segment, pki, post-quantum cryptography

4 terms

private investment in public equity financial

"SEALSQ’s $10 million private investment in public equity in WISeSat."

Private investment in public equity occurs when investors buy shares directly from a company that is publicly traded, often at an early stage or at a discount, instead of purchasing them on the open market. This allows investors to acquire a stake more quickly and with potentially better terms, which can influence the company's future growth and stability—making it an important option for those seeking to support or benefit from a company's development.

ground segment technical

"access to related mission control, ground segment, spectrum filing"

The ground segment is the collection of Earth-based equipment and teams that operate, monitor and receive data from satellites and spacecraft — things like antennas, control centers, mission planners and data-processing systems. It matters to investors because these systems determine whether a space service can reliably deliver data, maintain customers, meet regulations and control costs; think of the ground segment as the backstage crew and control room that keep a live performance running smoothly and on schedule.

pki technical

"Public Key Infrastructure (“PKI”), digital identity and cryptographic-key management"

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 technical

"By embedding Post-Quantum Cryptography into our semiconductor solutions"

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.
