In 2005, with Wang Xiaoyun and Hongbo Yu, Yin demonstrated an unexpected high probability of collisions (two different data values with the same hash) in the SHA-1 cryptographic hash function, originally designed by the National Security Agency. Their work caused SHA-1 to be considered as broken, and it has since fallen out of use. Yiqun Lisa Yin Yiqun Lisa Yin is a Chinese-American cryptographer and independent security consultant.
