US 2024/0202161 A1 · DATA MIGRATION USING COUNTER HASHING

Abstract

Techniques described herein are directed toward a counter hash generation scheme. One embodiment includes a method for counter hash generation. The method includes a device receiving an instruction to transmit an artifact from a source system to a target system, the artifact comprising a plurality of blocks. The device receives a block from the source system. The device generates an initialization vector based at least in part on the artifact. The device generates a nonce based at least in part on the initialization vector and a block value, each block being assigned a respective block value by a counter. The device generates a combined data instance based at least in part on a combination of the nonce, data of the block, and a length of the block. The device generates a hash of the combined data instance. The device transmits the hash and the block to the target system.
