LARES - Enhanced Security
LARES is a TETRA end to end encryption add-on data solution which will provide enhanced security on packet data and SDS messages up to SECRET level.
About LARES
LARES provides multi-bearer capability allowing applications to send secure authenticated messages to servers and to other terminals via the best bearer.
General
LARES provides cost effective, efficient and ultra-secure data communications across TETRA systems to central applications or to other terminals.
LARES runs as a software application on mobile data terminals connected to data-capable TETRA radios. It compresses and encrypts messages which are sent to a gateway co-located with the central data applications where they are decrypted, uncompressed and sent to the application server.
