Secure Chorus featured in The Journal of International Security “Staying Connected”
SECURE CHORUS, 29TH APRIL 2019
Secure Chorus discusses how major incidents require co-ordinated action across a range of stakeholders. This can be achieved through innovative standards that provide interoperability and security between Mission-Critical Push-to-Talk (MCPTT) communications and enterprise-grade communication apps.
The most widely used dedicated radio system for emergency services communications is the Terrestrial Trunked Radio (TETRA) standard, which remains reliable for voice communication. Many countries are evaluating the use of this commercial mobile infrastructure to deliver additional capabilities to the emergency services. As a result, it is essential to use products that secure data end-to-end, rather than relying on the security provided by commercial mobile networks, which may be not be sufficient in certain incident response scenarios.
To address this, 3GPP has defined the “Security of Mission-Critical Service”, mandating the open cryptography standard MIKEY-SAKKE. Facilitated by the fact that Secure Chorus’ interoperability uses the same cryptography standards as the MCPTT standards, there is now a much lower bar to providing assured interoperability between Mission-Critical Push-to-Talk (MCPTT) communications and enterprise-grade communication apps.
