Abstract
A system may include an attack preventing creator module that is configured to create at least one attack preventing head block for a message having message elements in a tree structure with one or more of the message elements being signed, wherein the attack preventing header block includes structure specific information that comprises at least a digest value of a pre-order traversal list of the tree structure and for each signed message element a unique ID attribute, a depth, a parent's name and a parent's ID attribute. The system may include an attack preventing verifier module that is configured to verify the at least one attack preventing header block by comparing the structure specific information which can be derived from the message with the structure specific information carried by the first attack preventing header block.
