WISeSat.Space Develops Post-Quantum Security for Satellite Communications

Insider Brief

• WISeSat.Space is developing a satellite communications and IoT security architecture that integrates post-quantum cryptography (PQC), digital identity, and cryptographic key management across connected devices, ground infrastructure, and future satellite platforms.
• The company plans to draw on SEALSQ’s QS7001 and QVault TPM platforms, which support NIST-standardized algorithms ML-KEM and ML-DSA, as it develops its Quantum Spatial Orbital Cloud.
• WISeSat.Space has access to nine active low-Earth-orbit satellites and targets a 100-satellite sovereign constellation by 2033, subject to financing, technical development, regulatory approvals, and launch availability.

PRESS RELEASE — WISeSat.Space (Nasdaq: SAIQ) (“WISeSat.Space” or the “Company”) today outlined its strategy to integrate post-quantum cryptography (“PQC”) into its next-generation satellite communications and Internet of Things (“IoT”) architecture, supporting the migration objectives established by U.S. Executive Order 14412, Securing the Nation Against Advanced Cryptographic Attacks.

The Company is developing a security architecture designed to protect communications, digital identities and satellite operations against both conventional cyberattacks and emerging quantum-computing threats. Its approach combines post-quantum semiconductor technologies from its sister company, SEALSQ Corp.’s (Nasdaq: LAES) with trusted digital identity and cryptographic key management across connected devices, ground infrastructure and future satellite platforms.
