The Apple iMessage Encryption Flaw
Researchers from Johns Hopkins (Christina Garman, Matt Green, Gabriel Kaptchuk, Ian Miers, and Michael Rushanan ) discovered a significant flaw in the way that Apple iMessage attachments such as pictures and videos are encrypted. As a result of this flaw, an attacker can potentially learn the secret cryptographic key used to encrypt messages and thereby learn the content of those messages. In this video, RSA’s Chief Technology Officer, Dr. Zulfikar Ramzan, provides a high-level description of the iMessage encryption flaw and its ramifications. Even without knowledge of cryptography or encryption, the viewer will walk away with a basic understanding of the key ideas in the flaw.
