Abstract

Protecting data in a message communicated from a sender to a receiver, the sender and receiver sharing a secret, comprising: splitting 704 the message into a number of ordered message blocks, generating 706, for each block, an encoded indication of a position of the block in a proper order of blocks as found in the original message, the encoding being reversible and based on at least a hash value for the content of the block and a secret shared between the sender and the receiver, and a position of the block in the proper order; communicating 708 the blocks and the encoded position indications to the receiver, the blocks being communicated in an order different to the proper order to obfuscate the message. The message can be reassembled by the receiver to the proper order by using the shared secret. The number of ordered message blocks that a message is divided into is variable and determined 702 on the basis of a performance analysis of the sender or receiver, the performance analysis determining a maximum number of hashing operations that can be performed by the device (e.g. hash speed) or execution time while satisfying a predetermined performance criterion.
