    摘要: An encryption apparatus and method is provided. The encryption apparatus includes a first block cipher which block-encrypts an N-bit input into an M-bit output in which M is greater than N; a parallel processor which divides the M-bit output into at least two N-bit inputs, and block-encrypts each of the N-bit inputs into each of M-bit outputs by a parallel process which uses second block ciphers corresponding to a number of the divided N-bit inputs; and a converter which converts a plaintext into a ciphertext based on the block-encrypted M-bit output.

    摘要: Provided are a method of generating a node identifier including padding information and location information, in a tree structure, a computer-readable storage medium storing a program for executing a method of generating a node identifier in a tree structure, and a terminal apparatus using the tree structure. The location information is generated by using branch identifiers, each of the branch identifiers being allocated for each branch from a root node to a target node. The padding information is generated by a padding code, which includes information about a group of the target node, and depth information, which includes information about a level of the target node in the tree structure.
