System and method for using a second resource to store a data element from a first resource in a first-in first-out queue

摘要

A system and method are provided for storing a data element from a first resource in a queue at a second resource. A combination of a data element XN+1 and a signature SQ=S[N] are signed at a first resource to obtain a signature S[XN+1,S[N]], where N is an integer. The data element data element XN+1 and the signature S[XN+1,S[N]] are sent from the first resource to the second resource to be stored in the queue at the second resource. The signature S[XN+1,S[N]] is stored at the first resource as the new value for SQ.
