Thales has launched a new report outlining how communications devices – such as those used by the police, private security and the military – could operate securely over mobile phone networks. Doing so would provide near universal range for secure communications.

The paper explains the strengths and weaknesses of various existing communication approaches, including walkie talkies, trunked PMR, and mobile networks. The former two offer security but limited range and require costly infrastructure to extend the range. Mobile networks offer extensive range but do not meet security requirements for high-security industries.

The proposed solution relates to modern encryption technology, which makes encrypting and decrypting voice data easily manageable within the device. The principle is similar to the way that emails can be secured over the internet by encrypting them between the sender and recipient.

When public infrastructure is needed to extend coverage, radios can link to an IP network such as LTE, 3G, or Wi-Fi. Voice data can be encrypted by the radio prior to being sent to the IP network and decrypted by other radios connected to the IP network once received, thus ensuring it is secured end-to-end.

To ensure trust in such a system, encryption must be implemented according to a recognised international standard such as The Advanced Encryption Standard AES, which is used by the US government.
