    • A method and system for a fair exchange of user information over a network is disclosed. The method comprises the steps of: transmitting over the network the user information encoded in association with a hidden value selected as one of a plurality of values distributed in a sequence wherein a difference between adjacent ones of said values increases and decreases symmetrically about one of the values of a known order; transmitting over said network a first set of the values and a last value in the sequence, wherein the values in said first set have increasing differences between adjacent ones of the values; and transmitting, individually, and in response to receipt of the other user's values, the remaining values in said sequence.
    • 公开了一种通过网络公平交换用户信息的方法和系统。 该方法包括以下步骤:通过网络传输用户信息,该用户信息与被选择为以下列顺序分布的多个值中的一个值相关联的隐藏值进行编码,其中相邻的所述值之间的差值对称地增加,并且关于 已知订单的价值; 通过所述网络发送所述值的第一组和所述序列中的最后值,其中所述第一组中的值在相邻值之间具有增加的差异; 并且单独地并且响应于接收到其他用户的值而发送所述序列中的剩余值。

    • A long-lived broadcast encryption method that adapts to the presence of compromised keys and continues to broadcast securely to privileged sets of users over time. In one aspect, a method for providing long-lived broadcast encryption comprises the steps of: allocating, to each of a plurality of subscribers, a corresponding set of subscriber keys; broadcasting encrypted content to the plurality of subscribers using a set of broadcast keys, wherein the encrypted content is decoded by a given subscriber using the subscriber's corresponding set of subscriber keys; modifying the set of broadcast keys, which are used for broadcasting encrypted content, by excluding compromised subscriber keys; and updating a set of subscriber keys corresponding to at least one subscriber when the at least one subscriber's set of subscriber keys comprises an amount of active keys that falls below a first predetermined threshold. In a long-lived broadcast encryption scheme, for any positive fraction β, a plurality of parameter values may be selected, a priori, in such a way to ensure that a steady state is achieved wherein, at most β of the total number of issued cards need to be replaced in a given recarding session.
    • 一种长寿命的广播加密方法,适应存在受损密钥,并随着时间的推移继续安全地广播到特权用户组。 一方面,一种用于提供长寿命广播加密的方法包括以下步骤:向多个用户中的每一个分配相应的一组用户密钥; 使用一组广播密钥将加密的内容广播到所述多个订户,其中所述加密的内容由给定的订户使用订户的相应订户密钥集进行解码; 通过排除受损的用户密钥来修改用于广播加密内容的广播密钥集合; 以及当所述至少一个用户的订户密钥组包括低于第一预定阈值的活动密钥的量时,更新与至少一个订户对应的一组订户密钥。 在长寿命的广播加密方案中,对于任何正分数β,可以先验地选择多个参数值,以确保实现稳定状态的方式,其中最多发布的总数为β 需要在给定的罢工会议中更换卡片。
