摘要： Provided are a method, client and system for reservation access to a management server using a one-time password. A generated personal identification number (PIN) is transmitted to the management server when a reservation time comes. The management server generates a random number encrypted using the PIN and transmits the random number to the client. The random number encrypted using the PIN is received, the received random number is encrypted by a symmetric-key algorithm using a client secret key and is transmitted to the management server. The management server receives the random number encrypted using the client secret key, and decrypts the received random number using a server secret key and the PIN. A random number before the encryption using the PIN is compared with a decrypted random number, and access of the client is accepted if the two numbers are identical. Automatic access to a system employing a one-time password authentication method can be made through an arbitrary route according to previously reserved settings to perform information collection and to process specific functions in the case where a system manager is unable to directly access the system through a determined route because of temporal and spatial limitations.
摘要翻译：提供了一种用于使用一次性密码预约访问管理服务器的方法，客户端和系统。当预约时间到来时，生成的个人识别号码（PIN）被发送到管理服务器。管理服务器生成使用PIN加密的随机数，并将随机数发送给客户端。接收使用PIN加密的随机数，使用客户端秘密密钥通过对称密钥算法对接收的随机数进行加密，并发送给管理服务器。管理服务器接收使用客户端密钥加密的随机数，并使用服务器密钥和PIN对接收的随机数进行解密。将使用PIN的加密之前的随机数与解密的随机数进行比较，如果两个数相同，则接受客户端的访问。可以根据先前保留的设置通过任意路由自动访问采用一次性密码认证方式的系统，以执行信息收集，并在系统管理者不能通过一个或多个系统管理器直接访问系统的情况下处理特定功能由于时间和空间的限制，确定的路线。
