Abstract: A method creates and distributes cryptographic keys for securing communication at two terminals. Signals for creating correlated values in the two terminals are distributed via a first communication channel burdened with error, and the correlated values are present as keys. A checksum is formed on the basis of the first key present in the first terminal and the checksum is transferred to the second terminal via a second communication channel. A second checksum is formed on the basis of the second key present, and information derived from the two checksums is transferred via the second communication channel to a server. Based on the information derived from the checksums, the server determines a correction value, which, when applied to one or both keys, brings the keys into correspondence. The correction value is transferred to one or both terminals via the second communication channel and is applied to one or both keys.

Abstract: A method detects discontinuities in an optical channel using two laser units that respectively have a laser and an electroabsorption modulator. The reference frequencies of the two lasers have a predetermined reference frequency difference. The optical ports of the electroabsorption modulator are fed to the two inputs of a polarization beam splitter and the output of the polarization beam splitter is connected to the optical channel. A test pulse is applied simultaneously to the two electroabsorption modulators and laser light from the lasers is thus transmitted through the respective electroabsorption modulators during the time of the test pulse. The test pulse is divided into two time periods, and during the first time period the lasers are operated with their respective reference frequency, and during the second time period the emission frequencies of the lasers are detuned with respect to the reference frequencies, by a predetermined detuning frequency difference.

Abstract: A method for checking the availability and integrity of a data object stored on a plurality of servers and having a number N of data words. For the distributed storage on the servers, the data object is fragmented. Each fragment is transmitted to and stored on one server. To check the availability and integrity of the fragments stored on the servers, the same random number is sent from an auditor unit to the servers. A checksum is created by the servers, in each case modified by application of the random number to the data of the respective fragment, and the checksum is transmitted to the auditor unit. The auditor unit uses the consistency check to determine whether the individual checksums sent by the servers are consistent and, if this is the case, establishes the availability and integrity of the data.
