Wonseok Choi works in cryptography, focusing on the mathematical design and rigorous security analysis of symmetric-key building blocks such as block ciphers, message authentication codes (MACs), and authenticated encryption schemes. Much of the work involves proving formal security guarantees (e.g., resistance to forgery or distinguishing attacks) for these constructions, including in settings with multiple users or misused nonces (values meant to be used only once). This research underpins the design of secure and efficient encryption tools used in computing systems.

Publication output has been modest but fluctuating over the last decade, with a slight uptick in 2020 and 2024, averaging under two papers per year in the most recent five-year period.
