基于多项式的认证方法、系统和用于示证者设备的方法
摘要：
本发明提供了包括多个设备(30)的系统(10)的认证方法。所述方法包括：a)为每个设备(30)提供身份值(pi：i＝1，n)和多项式(P)以产生多项式密钥；b)使所述设备(30)包括验证者设备(p1)和示证者设备(p2)；c)使所述示证者设备(p2)向所述验证者设备(p1)通知其存在；d)使所述验证者设备(pi)询问所述示证者设备(p2)，以使用示证者(p2)设备的多项式(P)密钥加密一次性数值，并将所述加密的一次性数值作为响应发送回所述验证者设备(p1)；e)使所述验证者设备(p1)从所述示证者设备(p2)接收作为进一步询问的所述加密的一次性数值，以及：(i)使用从一组已存储的设备身份产生的多项式密钥来加密所述询问；或者(ii)使用所述多项式密钥组来解密接收到的所述询问；直到所述验证者设备(p1)识别到认证匹配为止。
摘要（英）：

There is provided an authentication method for a system (10) comprising several devices (30). The method involves: a) providing each device (30) with an identity value (pi: i=1, . . . , n) and a polynomial (P) for generating a polynomial key; (b) including a verifier device (p1) and a prover device (P2)amongst said devices (30); (c) arranging for the prover device (p2) to notify its existence to the verifier device (P1); (d) arranging for the verifier device (pi) to challenge the prover device (p2) to encrypt a nonce using the prover (P2)device's polynomial (P) key and communicate the encrypted nonce as a response to the verifier device (p1); (e) arranging for the verifier device (p1) to receive the encrypted nonce as a further challenge from the prover device (pZ) and: (i ) encrypt the challenge using the polynomial keys generated from a set of stored device identities; or (ii) decrypt the challenge received using the set of polynomial keys; until said verifier device (p1) identifies an authentication match.
