The splendor falls on castle walls And snowy summits old in story: The long light shakes across the lakes, And the wild cataract leaps in glory. Blow, bugle, blow, set the wild echoes flying, Blow, bugle; answer, echoes, dying, dying, dying. —from The Splendor Falls by Alfred, Lord Tennyson This is the story of the closure of a hospital and with it a part of American pediatric history. Children's Seashore House of Atlantic City is the nation's fourth oldest pediatric hospital. After 118 years, it will close in the summer of 1990 and move to a new facility in Philadelphia. The simple brick, layer-cake structure looks very tired now, its iconic soul having been steadily removed for incorporation into the new hospital. The cornerstone animals, lions and bighorn, have been chiseled free and now guard a new outpost. So too have the plaques from the turn of the century, optimistically commemorating the establishment of endowed beds, wards, and cottages "for perpetual use" with their benefactors of simplicity and gentleness by name, such as the "Endowed Bed of St James Sunday School, 1889" and "Endowed by the Everyday Kindness Society, 1912." On this day, the workers hammer to remove the final link—an enormous marble tablet from 1919 eulogizing Dr William Bennett, the principal driving force of Children's Seashore House and also the founder of St Christopher's Hospital in Philadelphia. A mere 50 yards away, the Atlantic Ocean beats inexorably as it did at the founding in 1872, 2 years after the first planks were laid for the famous boardwalk.

Recently, Hosoyamada and Sasaki (EUROCRYPT 2020), and Xiaoyang Dong et al. (ASIACRYPT 2020) proposed quantum collision attacks against AES-like hashing modes AES-MMO and AES-MP. Their collision attacks are based on the quantum version of the rebound attack technique exploiting the differential trails whose probabilities are too low to be useful in the classical setting but large enough in the quantum setting. In this work, we present dedicated quantum free-start collision attacks on Hirose’s double block length compression function instantiated with AES-256, namely HCF-AES-256. The best publicly known classical attack against HCF-AES-256 covers up to 9 out of 14 rounds. We present a new 10-round differential trail for HCF-AES-256 with probability 2−160, and use it to find collisions with a quantum version of the rebound attack. Our attack succeeds with a time complexity of 285.11 and requires 216 qRAM in the quantum-attack setting, where an attacker can make only classical queries to the oracle and perform offline computations. We also present a quantum free-start collision attack on HCF-AES-256 with a time complexity of 286.07 which outperforms Chailloux, Naya-Plasencia, and Schrottenloher’s generic quantum collision attack (ASIACRYPT 2017) in a model when large qRAM is not available.
