With security vendor Utimaco

As a provider of digital certificate technology, DigiCert has extensive experience in cryptography, and is one of the first companies to be proactive. It is participating in the NIST call for proposals to develop standards for PQC. NIST emphasizes the importance of creating PQC with the following statement: “Historically, it has taken nearly two decades to deploy modern public-key cryptographic infrastructure. So whether or not we can accurately estimate when the quantum era will arrive, we must begin preparing our security systems to withstand the threat of quantum attacks.”

DigiCert, in collaboration and Microsoft, is developing a next-generation PKI that should address the main problems associated with the threat to modern encryption methods. “Our goal is to develop hybrid certificates for long-term protection that will include quantum-resistant algorithms in addition to RSA and ECC,” said Avesta Khodjati, head of research at DigiCert Labs.

The trio have achieved their first results. In February, DigiCert announced that it had successfully completed testing of Microsoft Research’s quantum-resistant Picnic algorithm with its digital certificates, which can be used to encrypt, authenticate, and ensure the integrity of connected devices.

DigiCert used Utimaco's Hardware Security Module to implement this algorithm and issue certificates. The hardware is expected to help issue digital certificates that are protected from hacking using quantum computing tools and provide secure key management, which will help companies secure their IoT deployments in the future.
