Abstract: A method of analyzing a program code of an electronic device includes configuring a tree by using a key string included in the program code and; in response to a command to find a specific key being received, performing a predetermined order traversal of the tree by using a string included in the specific key; in response to a node which matches a last string included in the specific key having a leaf node as a result of the predetermined order traversal, returning a value of the leaf node; and analyzing the program code by using the return value.

Abstract: An encryption apparatus includes a setting generator configured to generate an increasing function parameter regarding a predetermined one-way increasing function and a secret key necessary for encryption, and an encryptor configured to generate a first order-preserving encryption area regarding a plaintext using the one-way increasing function where the increasing function parameter is applied, generate a second encryption area regarding the plain text using the secret key, and generate a ciphertext by concatenating the generated first encryption area and the generated second encryption area.
