- What encryption algorithm is used in GSM (Groupe Special Mobile)
- mobile phones? It is my understanding that some single-key
- encryption algorithm is used, where the phone company supplies
- both partisipants of the conversation the necessary key.
-
- How secure is this algorithm? And how about the phone companies?
-
- For those of you who are not familiar with GSM, it is a digital
- mobile phone system that will cover the whole of Europe. And
- no, the algorithm is not an XOR-operation, that much I already
- know. BTW, judging by the discussion here a while ago, we won't
- be able to sell those phones to the US...;)
