Satellite networks

need protection

Armed services rely on fast, dependable

situationdata

Precise, up-to-date information is crucial in command and

control scenarios. Situation reports with image and video

material often need to be transmitted over long distances.

Satellite links serve to connect field units to a central sta-

tion (e.g. a control center or headquarters), which in many

cases are on a different continent. This data must be pro-

tected against manipulation, and must not fall into the

hands of third parties.

Protecting communications in critical infrastructures

with secure backup networks

Organizations with a large number of field offices are usu-

ally networked over leased lines. But what happens if

these lines fail? In these situations, critical infrastructures

such as government networks (e.g. connecting the foreign

ministry) or supply networks (e.g. for power transmission)

have backup networks. Depending on the distance to be

covered, satellite may often be the only available backup

communications option. It is especially important that

backup networks intended to carry critical information are

equipped with specialized encryption devices to secure

data transmissions.

Protecting oil and gas exploration data

The data gathered during exploratory drilling is highly sen-

sitive and of great value to rival businesses. Teams on the

ground send the data back to a central office for evalu-

ation. This data provides a basis on which organizations

decide whether to continue exploration. As a capital asset

crucial to an organization's future, this data deserves spe-

cial protection.

The challenge

Most of the data transmitted over satellite links is unen-

crypted – in other words, unprotected. Satellite operators

and customers are unwilling to make the effort of deploy-

ing encryption because up to now the solutions have con-

sumed too much costly connection bandwidth.

Satellite networks’ data connections need to be protected

because they are vulnerable on two counts: First, the data

is unvariably transmitted unencrypted; second, the data

can be received anywhere within the satellite spot beam.

Satellite-based communications are used in the following

situations:

❙ For temporary high-speed mobile communications

(e.g.byarmedservices)

❙ For backup networks (e.g. in critical infrastructures)

❙ For teams working in geographically remote locations

(e.g. in oil and gas exploration)

In these situations, the data transmitted is so valuable

that it needs protection using strong encryption. This

encryption must not have an impact on the transmission

of communications.
