Dutch and French authorities have cracked another encrypted communication service that criminals allegedly used to communicate with each other. The service, named Matrix, was the successor to previously cracked services such as ANOM, Sky ECC, and EncroChat. Police were able to intercept over 2.3 million messages and were able to read along with conversations for months.
Why are these apps getting hacked? Wouldn’t just RSA 2048 be enough?
Encryption is easy, key exchange is not
Encryption is really really hard, and avoiding some form of sidechannel attack is much much harder.
Sure key exchange also isn’t trivial, but I would say that key exchange is significantly easier. Care to elaborate?
Encryption is trivial. Getting a reliable keystream is not.
It all depends on the framing 😁
