Abstract: An apparatus and a method for mapping out a compression function of a hash mode of operation for a block cipher are provided to be used in a light weight hash function in case that secrecy and integrity are concurrently necessary in a light weight environment like RFID. An apparatus for mapping out a compression function of a hash mode of operation for a block cipher(10) includes the first block ciphering unit, the second block ciphering unit, the first replacement unit, the third block ciphering unit, the fourth block ciphering unit and the second replacement unit. The first block ciphering unit performs block ciphering for an upper bit Hi-1 of Mi and an arbitrary n bit constant c by a key having a 2n length wherein the Mi is the i-th plain text message resulted from division of 2n bit plain text message by n bit. The second block ciphering unit performs block ciphering for Gi-1 by a key having a 2n length wherein the Gi-1 is one among remaining plain text messages resulted from division of Mi by n bit. The first replacement unit replaces a result value having n length, outputted by the first block ciphering unit, with an upper n/2 bit and a lower n/2 bit of the result value, outputted by the second block ciphering unit, and obtains two n bit values. The third block ciphering unit ciphers one n bit value, replaced by the first replacement unit, by a key having a 2n length. The fourth block ciphering unit performs block ciphering for the other n bit value, replaced by the first replacement unit, by a key having a 2n length. The second replacement unit replaces a result value, outputted by the third block ciphering unit, with a result value, outputted by the fourth block ciphering unit.

Abstract: PURPOSE: A method for encoding and decoding an electronic document is provided to assure the safety of an electronic commerce by supplying secrecy for an XML(Extensible Markup Language) electronic document and a conventional general electronic document through an XML encoding and decoding procedure about various electronic documents. CONSTITUTION: An electronic document to be coded is selected(301). If the electronic document is for partial encryption(302), the selected electronic document is encoded(304) and compressed(305). If a multiple access is supported for the electronic document(306), a user or a group to be decoded is selected(307) and a specific key is created(308). The created specific key is coded as a public key(312), the coded specific key is encoded(313), and an access unit is created(314). An XML encryption template is finally created by information selectively inputted according to a result of a multiple access to the coded and encoded electronic document(317).
