Kevin Mitnick - مستشار أمني ويعتبر من أقوى الهاكر في العالم - يثني على Signal وينصح بإستخدامه : Signal, an application from Open Whisper Systems, is a free, open-source VoIP system for mobile phones that provides true end-to-end encryption for both iPhone and Android.
The main advantage of using Signal is that the key management is handled only between the calling parties, not through any third party. That means that, as in SDES, new keys are generated with each call; however, the only copies of the keys are stored on the users’ devices. Since CALEA allows access to any record of a specific call, law enforcement would in this case only see the encrypted traffic across the mobile carrier’s line, which would be unintelligible. And Open Whisper Systems, the nonprofit organization that makes Signal, does not have the keys, so a warrant would be useless. The keys exist only on the devices at either end of the call. And once the call ends, those session keys are destroyed. Currently CALEA does not extend to end users or their devices. You might think that having encryption on your cell phone would drain your battery. It does, but not by much. Signal uses push notifications, as do the apps WhatsApp and Telegram. Thus you only see a call when it is incoming, which cuts down on battery use while you’re listening for new calls. The Android and iOS apps also use audio codecs and buffer algorithms native to the mobile network, so again the encryption is not draining a lot of power while you’re making a call. In addition to using end-to-end encryption, Signal also uses perfect forward secrecy (PFS). What is PFS? It’s a system that uses a slightly different encryption key for every call, so that even if someone does manage to get hold of your encrypted phone call and the key that was used to encrypt it, your other calls will remain secure. All PFS keys are based on a single original key, but the important thing is that if someone compromises one key, it doesn’t mean your potential adversary has access to your further communications --------------------------------------------------------------------------------------- المصدر : الفصل الثالث Wiretapping 101 من كتاب The Art of Invisibility
