What You Need to Know to Embrace the Imminent

Quantum Shift for Your Cryptography Future

By Eddy Zervigon, CEO of Quantum Xchange

Cryptography has long been essential in ensuring the protection of data and communication networks.
However, even as we rely on it to safeguard sensitive information, vulnerabilities continue to give cause
for concern. Remaining reliant on outdated cryptographic standards certainly adds to the dangers of
compromise. Most legacy systems still cling to standards like MD5, SHA-1, TLS 1.1, and SSL 3.0 years
after their prime.

The implications are significant. Networks are exposed to unnecessary risks with potential vulnerabilities
that are ripe for exploitation by threat actors. As we usher in an era of cloud-scaling and quantum
technologies, the stakes are raised even higher. With regulations such as CCPA, DORA, GDPR, HIPAA,
PCI, SOX, and others in play, organizations face the need to evolve or risk breaches that could seriously
compromise their operations.

The limits of PKE

For almost five decades, public key encryption (PKE) has been the standard-bearer for digital data
protection. Its architecture, which relies on the exchange of public and private keys to encrypt and decrypt
data, has been generally effective.
