    摘要： Mobile device assisted secure computer network communications embodiments are presented that employ a mobile device (e.g., a mobile phone, personal digital assistant (PDA), and the like) to assist in user authentication. In general, this is accomplished by having a user enter a password into a client computer which is in contact with a server associated with a secure Web site. This password is integrated with a secret value, which is generated in real time by the mobile device. The secret value is bound to both the mobile device's hardware and the secure Web site being accessed, such that it is unique to both. In this way, a different secret value is generated for each secure Web site accessed, and another user cannot impersonate the user and log into a secure Web site unless he or she knows the password and possesses the user's mobile device simultaneously.

    摘要： A “proxy re-signature system” provides various techniques for transforming a delegatee's signature on a message m into a delegator's on the same message m. Various embodiments of non-interactive re-signature generation processes are described. Various embodiments to aggregate part of signatures to reduce the size of re-signed signatures are also described. Various combinations of the proxy re-signature process and the re-signature conversion process result in an overall process that is unidirectional, multi-use, private, and non-interactive. As such, the proxy re-signature system is applicable for use with a wide range of applications.

    摘要： Described is an optimistic fair payment protocol in electronic commerce that provides fair payment while resisting an unconscious double spending attack and other attacks. A buyer receives encrypted e-goods from a merchant, and sends payment to the merchant. If decryption information is not received in exchange for the payment, or the decryption information does not render the e-goods useable, the buyer launches a dispute with a third party dispute resolution service. If the decryption information is received and renders the e-goods useable, the buyer determines whether the e-goods are valid, according to a corresponding description. If not valid, the buyer launches a dispute and provides the e-goods and the description. The third party uses the description to evaluate the validity of the goods to determine whether to refund the payment to the buyer or release it to the merchant.

    摘要： The embodiments of the present disclosure disclose a method and apparatus for reducing the parameter transmission bandwidth. The parameter sender reduces the values of the parameters before sending the parameters to the parameter receiver. This scheme reduces the bandwidth consumed during parameter transmission, thus makes the transmission more efficient. The embodiment of the present disclosure also discloses a method for key exchange. This method reduces the values of the transmission parameters before sending the transmission parameters. This saves the bandwidth compared with the protocol in the prior art. Besides, the embodiment of the present disclosure discloses a system for key exchange. The parameter sender sends the transmission parameters to the bandwidth processing unit. The bandwidth processing unit performs a modulo operation on the received transmission parameters and then sends the processed transmission parameters to the parameter receiver, thus reducing the bandwidth consumed in the transmission of transmission parameters.

    摘要翻译： 本公开的实施例公开了一种用于减少参数传输带宽的方法和装置。 在将参数发送给参数接收器之前，参数发送器减少参数的值。 该方案减少参数传输期间消耗的带宽，从而使传输更有效率。 本公开的实施例还公开了一种用于密钥交换的方法。 该方法在发送传输参数之前减少传输参数的值。 这节省了与现有技术中的协议相比的带宽。 此外，本公开的实施例公开了一种用于密钥交换的系统。 参数发送方将传输参数发送到带宽处理单元。 带宽处理单元对所接收的传输参数进行模运算，然后将经处理的传输参数发送到参数接收机，从而减少传输参数传输中消耗的带宽。
