1. An apparatus for guaranteeing integrity of real-time vehicle data, comprising:

  • a non-transitory computer-readable storage medium having encoded thereon instructions for guaranteeing integrity of real-time vehicle data; and

    a processor that executes the instructions, wherein the processor;

    divides input data streams about sensing information for a vehicle into divided block data of a predetermined size;

    generates initial authentication data (IAD) by signing an initial block data of the input data streams by a signing key;

    generates for each of the divided block data in order, a first hash value by;

    concatenating and hashing a value of the present block data and a previous block data'"'"'s first hash value; and

    generating for each of the divided block data in order, a second hash value by;

    hashing the present block data'"'"'s first hash value and outputting the present block data'"'"'s second hash value as integrity verification data of the present block data,wherein the IAD is used as the initial block data'"'"'s first hash value.
