    Abstract: PURPOSE: An access and location authentication device of a smart device and an access and location authentication method using the same are provided to authenticate locations by eliminating and issuing token for authenticating a location. CONSTITUTION: An access authentication server(130) executes wireless communication with a smart device through a first wireless communication device and a second wireless communication device. The access authentication server obtains the access authentication information of a smart device. The access authentication server confirms the access authentication information in user database(140). The user database stores the information of the smart device and necessary information for authenticating users who belongs to a first area or a second area. An access recording database(150) stores the access time of the smart device, an authentication result, and a token issuing state.

    Abstract: PURPOSE: An ID based sign cryption method which guarantees anonymity and an authenticity of a cryptogram is provided to improve the efficiency of a cryption system by reducing a hash calculation. CONSTITUTION: Using at least one among a random number with an arbitrary number of bits, a concatenation calculation result of a transmitter ID data, an ID data of a receiver, and a private key which the transmitter inputted, the value which encrypted each of the message and signature value is included in the cryptogram(100). Using the cryptogram, the private key which the receiver inputted, and the concatenation calculation result of the message and the ID data of the receiver, the ID data and the cryptogram of the receiver in which the transmitter inputted are verified whether it is same as the ID data of the receiver who have received. [Reference numerals] (110) Random number r ' {0, 1}^*; (160) Signature value s = S_IBS ((m || ID_R), SK_IBS.IDS)

    Abstract translation: 目的：提供一种基于ID的签名加密方法，其保证密码的匿名性和真实性，以通过减少哈希计算来提高加密系统的效率。 构成：使用具有任意位数的随机数中的至少一个，发送器ID数据的连接计算结果，接收器的ID数据和发送器输入的私钥，加密每个 消息和签名值包括在密码（100）中。 使用密码，接收机输入的私钥，接收者的ID数据，接收者的ID数据和接收者的密码等，验证接收者输入的私钥是否与 收到的接收者的ID数据。 （附图标记）（110）随机数r'{0,1} ^ *; （160）签名值s = S_IBS（（m || ID_R），SK_IBS.IDS）
