DECT (part II)

What has changed in DECT security after one year

After dedected.org was published on 25C3, lots has changed in DECT security.

This talk provides an update on the security of encrypted DECT calls that use the DSC cipher. This cipher which is supposed to protect DECT phones from passive eavesdropping can finally be broken in some scenarios. We also show what has been done so far to improve DECT security and what you can to to get a secure DECT system.
