COLLUSION-RESISTANT IDENTITY-BASED AND QUANTUM-RESILIENT SECURE CORRELATION SCHEMES

原文（中国語）

Techniques for securing a digital ecosystem are disclosed. In embodiments, a method includes storing a master QNA object comprising s symmetric matrices, each having d rows. The master QNA is structured to allocate correlated QNA objects to cohorts of the digital ecosystem based on credentials of the cohorts. The method includes receiving a unique identifier of a cohort being admitted to the ecosystem; determining a set of s selection values based on the unique identifier of the new digital cohort and a selection function; and allocating a new QNA object comprising s vectors to the cohort based on the s selection values and the s matrices. Each selection value is between 1 and d and corresponds to a respective composite matrix of the s composite matrices such that each selection value indicates a specific row of the respective matrix to which the selection value corresponds.
