Abstract

See full text

A computer-implemented method for storing an object includes providing an object, an ordering vector of the object, the ordering vector being associated to a lexicographic order having at least one dimension, and base keys associated to each dimension of the lexicographic order; deriving a key by retrieving the base key associated to the first dimension of the lexicographic order for which the ordering vector has a value different from the smallest value, and applying a one-way function a number of times corresponding to the value of the ordering vector for the last dimension of the lexicographic order; encrypting the object with the key; and storing the object as encrypted.
