SEALSQ Corp (NASDAQ: LAES) announced it is implementing post-quantum cryptographic technologies to secure blockchain and digital transaction infrastructures as quantum computing advances toward practical use.

The company is deploying NIST-selected post-quantum cryptography algorithms, including CRYSTALS-Kyber for key encapsulation and CRYSTALS-Dilithium for digital signatures, to replace traditional elliptic curve schemes. These algorithms are embedded in SEALSQ's secure elements and TPM-class chips.

The technology addresses concerns about quantum computers potentially breaking current cryptographic systems. While current quantum systems remain limited to noisy intermediate-scale quantum devices, SEALSQ is preparing for future quantum threats that could compromise RSA or elliptic curve cryptography.

SEALSQ is collaborating with WeCan, a Swiss blockchain financial platform, to apply these technologies to financial-grade blockchain transactions. The implementation includes secure multiparty computation, zero-knowledge proof frameworks, and hardware-backed identity validation.

Through SEALCOIN.AI, a subsidiary of parent company WISeKey International Holding Ltd (SIX: WIHN; NASDAQ: WKEY), SEALSQ extends this security architecture to machine-to-machine transaction infrastructures. The SEALCOIN protocol is designed as a cross-industry transaction layer for secure interactions between devices across energy, mobility, data, and space communication sectors.

The company's WISeSat.Space subsidiary integrates these capabilities into satellite infrastructure, with onboard chips embedding post-quantum secure boot, firmware integrity verification, and encrypted communication channels.

"By embedding post-quantum cryptography directly into semiconductors, blockchain protocols, and space-based infrastructure, we are taking a proactive approach to this shift," said Carlos Creus Moreira, Founder and CEO of SEALSQ.
