Classification: CPC H | IPC G  H

Claim 0:
1. A method for compiling a cryptographic information, comprising:
(a) determining a first portion of the cryptographic information based on an input and a randomness;
(b) checking whether a rejection criterion based on the first portion of the cryptographic information is fulfilled; and
(c) re-starting step (a) with a new randomness in the event the rejection criterion is fulfilled with respect to the first portion of the cryptographic information; and,
(d) for each of at least one subsequent portion of the cryptographic information not yet determined,
(d1) determining the subsequent portion of the cryptographic information based on the input and the randomness for which the rejection criterion based on the first portion of the cryptographic information was not fulfilled,
(d2) checking whether the rejection criterion is fulfilled based on the subsequent portion of the cryptographic information, and
(d3) re-starting step (a) with a new randomness in the event the rejection criterion is fulfilled with respect to the respective subsequent portion of the cryptographic information; and

(e) conveying the determined first portion of the cryptographic information and each determined subsequent portion.
