SEALSQ Corp
SEALSQ is a Swiss-based semiconductor company that specialises in developing secure microcontrollers and implementing post-quantum cryptography. A subsidiary of WISeKey, SEALSQ provides the hardware foundation for securing connected devices in a wide array of industries, including smart energy, automotive, industrial automation, and consumer electronics.
SEALSQ’s product portfolio is centred on providing end-to-end digital security. This includes the VaultIC family of secure elements, which are tamper-resistant microcontrollers offering cryptographic services for authentication and data integrity. They also develop secure ARM platforms and are pioneering post-quantum RISC-V chips to protect against future threats from quantum computing. Beyond the chips themselves, SEALSQ provides Public Key Infrastructure (PKI) and provisioning services, allowing for the secure management of a device’s digital identity throughout its lifecycle.
SEALSQ is partnered with Hedera to integrate its quantum-resistant semiconductors directly into the Hedera network's infrastructure. This partnership aims to protect the Hedera ecosystem from the emerging threat of quantum computing by "future-proofing" digital signatures and communication channels. Specifically, SEALSQ's hardware will be used in the SEALCOIN project, a tokenised platform for machine-to-machine (M2M) transactions on Hedera, which is a core component of the DePIN (Decentralised Physical Infrastructure Network) being developed by WISeKey and its subsidiaries.
