The analysis of Apple's iMessage PQ3 Protocol highlights significant security features employed by Apple to protect user communications. However, it has sparked debate regarding the effectiveness and implications of iCloud's role in storing encryption keys, which may compromise user privacy. A commenter raised concerns about Apple's practice of storing a copy of encryption keys in iCloud, enabling potential access to user data by law enforcement. This suggests a possible gap between perceived and actual security in Apple's messaging system. The critiques indicate the importance of transparency around privacy policies and user data handling.
