    • PURPOSE: An authentication method using a public key encryption system is provided to enhance an operation speed and the reliability of encryption by using a public key encryption system based on a braid group. CONSTITUTION: One or more braids are selected from braid subgroups of an arbitrary braid group and the selected braids are stored as secret keys(SA100). A public key is formed by using the secret keys(SA101). The public key and the private data are transmitted to an authentication center(SA102). An applicant receives the public key and a signature from the authentication center and transmits the public key and the signature to an authentication inspector(SA103-SA106). The authentication inspector acknowledges the public key and selects an arbitrary integer if the signature is valid. The applicant selects plural integers including integers related to the selected integer and calculates the braids of the braid group or the braid sub-groups by using the integers, the secret keys, and the public key. The applicant transmits the information including the braids and calculation values of fundamental braids. The authentication inspector decides the authentication by using the braid group, the braids, the information, and the public key.
    • 目的:提供使用公钥加密系统的认证方法,通过使用基于编织组的公钥加密系统来提高操作速度和加密的可靠性。 构成:从任意辫子组的编织子组中选择一个或多个辫子,并将选定的辫子存储为秘密密钥(SA100)。 通过使用秘密密钥(SA101)形成公开密钥。 公开密钥和专用数据被发送到认证中心(SA102)。 申请人从认证中心接收公开密钥和签名,并将公开密​​钥和签名发送给认证检查员(SA103-SA106)。 验证检查员确认公钥,如果签名有效,则选择任意整数。 申请者选择多个整数,包括与所选择的整数相关的整数,并通过使用整数,秘密密钥和公钥来计算编织组或编织子组的编织物。 申请人发送包括辫子和基本辫子的计算值的信息。 认证检查员通过使用编织组,编织物,信息和公钥来确定认证。

    • PURPOSE: A method for signing and identifying information using a public key encryption system is provided to sign and identify the information by using the public key encryption system based on a braid group. CONSTITUTION: A signer selects one or more braids from braid subgroups of an arbitrary braid group, stores the selected braids as secret keys, and opens the remaining braids as public keys to the public(SA100-SA106). The signer selects arbitrary integers satisfying a predetermined function, obtains the predetermined braids by calculating the secret keys, the public keys, the integer, and a message, and transmits the braids to a receiver. The receiver obtains the braids by using the braids and the public keys and identifies the identity of signature between the obtained braids.
    • 目的:提供使用公钥加密系统签名和识别信息的方法,通过使用基于编织组的公钥加密系统对信息进行签名和识别。 构成:签名者从任意辫子组的编织子组中选择一个或多个辫子,将所选辫子存储为秘密键,并将剩余的辫子作为公共密钥打开(SA100-SA106)。 签名者选择满足预定功能的任意整数,通过计算秘密密钥,公开密钥,整数和消息获得预定的辫子,并将辫子发送给接收者。 接收者通过使用辫子和公钥获得辫子,并识别所获得的辫子之间签名的身份。
