摘要： A method is presented for enabling authentication of a prover in a Radio Frequency Identification system comprising the prover and a verifier, the method comprising the steps of: the prover sending a prover identifier and a parent identifier to the verifier, the verifier sending a verifier identifier to the prover, the prover calculating a first common secret by means of a prover polynomial, where an unknown in the prover polynomial is substituted by a result calculated using a function of at least the verifier identifier, and the verifier calculating the first common secret by means of a first verifier polynomial, wherein a first unknown in the first verifier polynomial is substituted by the prover identifier and a second unknown in the first verifier polynomial is substituted by the parent identifier, the prover creating a first message by modulating a first core secret with regard to at least the first common secret, aid prover sending the first message to the verifier, and the verifier creating a first candidate for the first core secret by demodulating the first message with the first common secret, whereby the candidate for the first core secret is for use in the authentication. This allows the verifier and prover to independently create a common secret, used for modulating the core secret. Furthermore, no pre-registration of the prover with the verifier is required and calculation using polynomials requires little processing power. A corresponding system, prover and verifier are also presented.

摘要： The invention relates to a method for proving authenticity of a prover PRV to a verifier VER, the method comprising generating a secret S using a physical token by the prover PRV. Obtaining a public value PV by the verifier, where the public value PV has been derived from the secret S using a function for which the inverse of said iunction is computationally expensive. The method further comprising a step for conducting a zero knowledge protocol between the prover PRV and the verifier VER in order to prove to the verifier VER, with a pre-determined probability, that the prover PRV has access to the physical token, where the prover PRV makes use of the secret S and the verifier VER makes use of the public value PV. The invention further relates to a system employing the method, and an object for proving authenticity.
摘要翻译：本发明涉及一种用于向验证者VER验证证明者PRV的真实性的方法，该方法包括使用证明者PRV使用物理令牌生成秘密S。通过验证者获得公共值PV，其中公共值PV已经从秘密S导出，使用所述结点的倒数在计算上是昂贵的函数。该方法还包括用于在证明者PRV和验证者VER之间进行零知识协议的步骤，以便以预先确定的概率向验证者VER证明证明者PRV可以访问物理令牌，其中证明者 PRV使用秘密S，验证者VER利用公共价值PV。本发明还涉及采用该方法的系统和用于证明真实性的对象。
