BlackHat 2016: roundup of iOS security

A few interesting presentations last week at BlackHat dealt with iOS security. The most interesting was Ivan Krstić’s presentation taking us “Behind the Scenes with iOS Security.” Krstić, Apple’s head of security engineering and architecture, reviewed the implementation of features like Keychain Backup, file encryption, sharing of credit card information across devices, etc.

I particularly enjoyed the description of how the cloud-based key vaults for iCloud are protected:
