TETRA algorithm TEA1 backdoor confirmed
ETSI kept in secret the TEA1 algorithm backdoor for many years. Slovenia used this algo until recently.
In 2013 I received information from a source in the Croatia Intelligence and security agency (SOA) that TEA1 algo was cracked. This information has been handled to employee of the Slovenian Police.
Slovenska policija / The Slovenian police was the killer in my case. Kill the Messenger was and still is their moto.
Shame on you Slovenia and shame on you Slovenian Police!
