Satellite telephony is unsafe
RUB scientists break security standards
Encryption algorithms have security gaps
Satellite telephony was thought to be secure against eavesdropping. Researchers at the Horst Görtz Institute for IT-Security (HGI) at the Ruhr University Bochum (RUB) have cracked the encryption algorithms of the European Telecommunications Standards Institute (ETSI), which is used globally for satellite telephones, and revealed significant weaknesses. In less than an hour, and with simple equipment, they found the crypto key which is needed to intercept telephone conversations. Using open-source software and building on their previous research results, they were able to exploit the security weaknesses.
