Addressing security issues

Secure Chorus and ISARA Corporation announce joint white paper ‘The Quantum Revolution: Security Implications and Considerations’ to address the security issues raised by quantum computing and introduces quantum-safe equivalents to replace current public key cryptosystems. 

The white paper introduces the identity-based public key cryptography MIKEY-SAKKE and offers a possible approach to make MIKEY-SAKKE quantum-safe highlighting the importance of doing so, due to the unique benefits this type of cryptography offers to enterprises.  The paper also provides a framework for assessing when work should start on replacing public key cryptosystems.

The paper introduces the MIKEY-SAKKE identity-based public key cryptography standard, and explains that this cryptography standard, if made quantum safe, would continue to offer a combination of benefits if compared with other quantum safe cryptography.  It is highly scalable, requiring no prior setup between users or distribution of user certificates.  It is flexible, supporting real-time communications, conference calls, and deferred delivery, such as messaging and voicemail. It is designed to be centrally managed, giving a domain manager full control of the security of the system while maintaining availability, as calling does not require interaction with centralised architecture.

To help organizations assess if and when they need to start working on protecting themselves against the threat posed by quantum computers, the paper highlights the following key considerations: how long an organization is required to retain sensitive information, as well as how long a full transition to post-quantum cryptography will take, providing a framework for assessing when work to make cryptography standards quantum-safe should start.
