Program protection device

In a method for verifying the integrity of first to Nth binaries (N is a natural number greater than or equal to 2), the method may comprise: loading the first to Nth binaries into a main memory in order to execute the binaries; verifying a self hash to verify, by the Kth binary (K=1, . . . , N&#x2212;1) which has been loaded into the main memory, the integrity thereof by using a hash; and verifying a link hash by setting any one of the first to Kth binaries as a verification binary and setting a (K+1)th binary to be loaded into the main memory as a binary to be verified so that the verification binary verifies the integrity of the binary to be verified by using a hash.
