Apple is rolling out a significant update to its iMessage service with iOS 17.4, introducing “Level 3” security for enhanced messaging protection.

Level 3 Security: What’s New?

  • Advanced cryptography secures messages at two levels: when the conversation starts and during the conversation.
  • Frequent key changes prevent bad actors from unlocking all messages with a single compromised encryption key.

Why is This Important?

  • Quantum computing poses a future threat to current security methods.
  • Apple aims to proactively combat this threat with its updated security measures.
  • The timeline for a sufficiently powerful quantum computer to pose a significant threat is estimated to be 10-15 years.

What Does This Mean for Users?

  • iOS 17.4 brings a new standard for secure messaging apps.
  • The update is rolling out soon for iPads and Mac devices as well.

This update represents Apple’s commitment to safeguarding user privacy and protecting messages from potential vulnerabilities.
