    Abstract: Disclosed herein are an apparatus for generating the privacy-protecting document authentication information and a method of performing privacy-protecting document authentication. The apparatus for generating the privacy-protecting document authentication information includes an electronic signature information generation unit, a multi-dimensional code generation unit, and a multi-dimensional code output unit. The electronic signature information generation unit generates electronic signature information for the content of an input document. The multi-dimensional code generation unit generates a multi-dimensional code corresponding to the generated electronic signature information. The multi-dimensional code output unit outputs the generated multi-dimensional code onto the document.

    Abstract: Exemplary embodiments of the present invention relate to a batch verification method for verifying a plurality of authentication data or digital signature values and an apparatus thereof. A batch verification method according to an embodiment of the present invention comprises: rearranging N pairs of individual instances which compose a batch verification instance; selecting N−1 verification exponents from a verification exponent set E which is used for the batch verification; and performing the batch verification for the rearranged batch verification instance by using the selected verification exponents. Exemplary embodiments of the present invention can be suitable for digital signature and cryptographic confirmation. According to exemplary embodiments, verification computation amount of a plurality of authentication data or digital signature values can be significantly reduced.

    Abstract: Disclosed herein are an apparatus and method for anonymity-based authentication and key agreement capable of providing a communication message binding property. The apparatus includes a signature verification unit and a binding checking unit. The signature verification unit receives a plurality of messages, each carrying a signature including link information of a sender, and verifies the signature of each of the plurality of messages. The binding checking unit, if it is determined by the signature verification unit that the signature is valid, determines whether the plurality of messages has been sent by an identical sender based on the link information of the signature.
