    • Aspects relate to systems and methods implementing a scheme allowing a Verifier (V) to authenticate a Prover (P). The scheme comprises pre-sharing between V and P a graph of nodes. Each node is associated with a polynomial. V sends P data comprising data for selecting a polynomial of the graph, such as traversal data for proceeding from a known node to another node, a time interval, and a number k. P uses the time interval in an evaluation of the polynomial. P then uses the evaluation as a λ in a Poisson distribution, and determines a value related to a probability that a number of occurrences of an event equals k. P sends the determined value to V. V performs a similar determination to arrive at a comparison value. P authenticates V if the separately determined values match, or otherwise meet expectations. The process can be repeated to increase confidence in authentication.
    • 方面涉及实现允许Verifier(V)验证Prover(P)的方案的系统和方法。 该方案包括在V和P之间预先共享节点图。 每个节点与多项式相关联。 V发送包括用于选择图形的多项式的数据的P数据,例如用于从已知节点进行到另一个节点的遍历数据,时间间隔和数量k。 P在多项式的评估中使用时间间隔。 P然后使用评估作为? 在泊松分布中,并且确定与事件的发生次数等于k的概率相关的值。 P将确定的值发送到V.V执行类似的确定以得到比较值。 如果单独确定的值匹配,则P验证V,否则满足预期。 可以重复该过程以增加认证的置信度。
