  1. Security and Smartphones By Parker Moore

  2. The Smartphone Takeover • Half of mobile phone subscribers in the United States have a smartphone. • An estimated 128 million smartphones • Over 90% of these people are on Verizon, AT&T, Sprint, and T-Mobile.

  3. Uses of Smartphones • Sending and Receiving emails • Money transactions • Entertainment • Social Networking • Location based navigation • Surfing the internet

  4. The Two Contenders iPhone Android Many different phones, single OS Open source operating system “Android market” for software downloads • A single line of phones, single OS • Closed source operating system • “App store” for software downloads

  5. iPhone Security Measures • “Chain of trust” • Boot ROM • Low Level Bootloader • “iBoot” runs the OS kernel • Apple Signed Code only • No Operating System Downgrading • Prevents use of old vulnerabilities

  6. iPhone Security Measures • Third party applications run in a “Sandbox” • Applications are designated a random “home” directory • Applications may not access another applications data • If an application does need to access outside of its sandbox it must use a designated API.

  7. iPhone Security Measures • AES encryption • AES 256-bit keys fused into the application processor during manufacturing • AES crypto engine built into path between flash storage and main memory • Passcodes • 4 digit and arbitrary length • Iteration count to slow down brute force • Optional: wipe device after 10 failed passwords

  8. Carriers and Privacy • Typically, smartphones are connected to the internet through a data plan arranged with a cellphone provider. • Carriers have too much information about the user • As many as 1.3 million request for call information made by law enforcement • Potential for GPS tracking

  9. Conclusion • Cell phones are a great innovation • In many cases, consumers must trust creators to be smart about security • Should still strive to keep personal information personal • Utilize extra security features available if necessary
