The IACR's primary activity each year is the organization of the three main cryptologic conferences, and four more specialist workshops. The IACR board selects the venue of the main conferences, from a number of candidate places, although the Crypto conference is always held in Santa Barbara. The IACR board also selects the two programme co-chairs. The determination of the scientific programme is then delegated to the programme co-chairs.
For each of the four workshops there is an individual steering committee which appoints programme chairs, and determines the location.
IACR cooperates with other organizations for their workshops and conferences, all of which are listed here.
