Quantum key distribution in a multi-cloud environment

A computer system for detecting data corruption between storage systems, the computer system comprising:

• one or more computer processors;
• one or more computer readable storage devices;
• program instructions stored on the one or more computer readable storage devices for execution by at least one of the one or more computer processors, the stored program instructions comprising:
• program instructions to perform information tunneling on data transferring between a source storage system and a target storage system;
• program instructions to calculate a checksum of a data payload for an Internet Protocol (IP) packet and requesting submission to a blockchain ledger along with an IP packet serial number and the checksum;
• program instructions to determine the checksum data of the data payload of the data transferring does not match the IP packet checksum and a blockchain based checksum, wherein determining comprises:
• program instructions to compare the checksum data at the target storage system against the IP packet extracted checksum and the blockchain based checksum to identify one or more checksum mismatches between the checksum data at the target storage system and at least one of the IP packet extracted checksum and the blockchain based checksum;
• program instructions to identify a corruption in the data payload of the data transferring based on the comparison between the checksum data at the target storage system and the IP packet extracted checksum and the blockchain based checksum;
• responsive to receiving a predetermined number of checksum mismatches that trigger a security breach isolation demanding corrective actions, program instructions to validate the corruption in the data payload of the data transferring;
• and
• program instructions to update respective entities of identified corruption in the data payload of the data transferring.
