The 2nd Crypto Innovation School (CIS 2019)

An IACR Cryptology School

Dates: December 13th-December 15th, 2019

Location: Shanghai, China. Shanghai, on China's central coast, is the country's biggest city and a global financial hub. Its heart is the Bund, a famed waterfront promenade lined with colonial-era buildings. Across the Huangpu River rises the Pudong district's futuristic skyline, including 632m Shanghai Tower and the Oriental Pearl TV Tower, with distinctive pink spheres. Sprawling Yu Garden has traditional pavilions, towers and ponds.

Objective: After the first successful crypto innovation school last year, the organizers continue to hold the second CIS winter school this year. CIS2019 has gained support from Tsinghua University and Shanghai Jiao Tong University as well as industry funding sources. Although the main targeted audience are graduate students, postdocs (and young faculties) in cryptography from the Asia-pacific region (mainland China, Taiwan, Hong Kong, Japan, Korea,Singapore, Australia), the winter school is open to researchers of all levels and from all around the globe. All lectures and talks will be delivered in English.

Affiliated event: Crypto innovation school competition (CISC) is a new annual event under crypto innovation school. Offered with generous rewards, CISC aims to encourage and promote creative and talented works on cryptography. Winners of the competition this year will be formally announced during CIS 2019. More information and details of CISC can be found at the competition website.


The theme of the winter school this year is lattice-based cryptography, which includes (but is not limited to) the mathematical foundations of lattice, lattice reduction and advanced cryptographic schemes based on lattices.


The school intends to admit 100 (and more up to the maximum capacity of the venue) attendees. Registration is free, but due to the limited number of space and budget, attendees need to apply for admission. Participants are required to have taken at least one university-level course in cryptography in advance. In addition, applicants who are not native English speakers are expected to exhibit good English skills in their CV. Applications are considered at the discretion of organizers on a first-come-first-served basis until the capacity is reached. Further, 10 stipends each of $500 (or equivalent) are available to students unable to obtain funding to attend the conference.

To apply for admission, send your CV to and in the meantime please indicate if you are eligible (i.e., as a student have no financial support for this trip) for the student stipend.

Application deadline: October 30, 2019
Notification date: November 10, 2019


Jumeirah Himalayas Hotel Shanghai

Located in Shanghai, the city where Eastern tradition and modern influences fuse to provide a vibrant cultural backdrop, the Himalayas Hotel stands as an iconic landmark of this eclectic fusion. Designed by Arata Isozaki, our hotel’s architecture and interiors take inspiration from the cultural essence of China. From the artwork across the hotel's 16-metre-high lobby that tells a 5,000-year-old story to all the modern facilities that lace the bars, restaurants, rooms, and conference halls, every aspect symbolises unity, prosperity and good luck.

The Jumeirah Himalayas Hotel (Zhuomeiya Ximalaya Jiudian) offers 5-star luxury in the heart of Pudong with direct underground access to the Shanghai New International Expo Center and the leafy environs of  Century Park. It's also just a short walk from the  Shanghai Maglev train station, which takes just seven minutes to reach Pudong International Airport .
