Ivan Krstić is a Croatian computer security expert, currently working on core security at Apple Inc. Krstić was previously the director of security architecture at One Laptop per Child. He is a co-author of The Official Ubuntu Book (ISBN 978-0-13-243594-9).
Early Life and Education
Ivan Krstić was born in Croatia and demonstrated early academic promise, earning a scholarship to attend Cranbrook Kingswood school in Michigan, United States, at the age of 15. In 2004, he enrolled at Harvard College, though his path through higher education was marked by deliberate interruptions in pursuit of meaningful technical work.
Career
During his first leave from Harvard, Krstić worked on secure electronic healthcare systems at Croatia's largest children's hospital, applying his security expertise to a critical real-world domain. After returning to Harvard in 2005, he took a second leave of absence when he was offered a position with One Laptop per Child (OLPC), the nonprofit initiative aimed at providing low-cost educational laptops to children in developing countries.
At OLPC, Krstić served as Director of Security Architecture, where he designed the Bitfrost security architecture — a comprehensive security platform built specifically for the project's XO laptop. Beyond the design work, he personally oversaw the project's first two in-country deployments, in Uruguay and Peru. He departed OLPC in early 2008.
In May 2009, Krstić joined Apple Inc., where he has worked on core security. His role at Apple places him among the engineers responsible for the foundational security systems underpinning Apple's platforms and products.
Notable Work
Krstić is co-author of The Official Ubuntu Book (ISBN 978-0-13-243594-9), contributing to one of the prominent reference works on the Ubuntu Linux distribution. His Bitfrost security architecture, developed during his time at OLPC, represented a notable effort to bring robust, purpose-built security to resource-constrained computing environments intended for use by children in developing nations.
Recognition
In 2007, Krstić was named a TR35 laureate by MIT Technology Review, which selected him as one of the world's top 35 innovators under the age of 35. The following year, eWeek magazine recognized him as one of the three most influential people in modern computer security, and placed him among the top 100 most influential figures across all of information technology.
