私人握手
Private Handshakes
摘要：
私人握手允许成对的用户确定他们都是哪个（秘密）组的成员。小组成员身份对其他人保密。私有握手是一种更私密的秘密握手形式，因为它不允许组管理员跟踪用户。我们扩展了握手协议的原始定义，允许和测试多个组的成员资格同时进行。我们提出了简单而有效的协议，为单组和多组成员的情况下。私有握手是一种用于相互认证的有用工具，许多普及应用（包括RFID）都需要这种工具来保护隐私。我们的实现是有效的，足以支持这种通常资源受限的情况。
英文摘要：
Private handshaking allows pairs of users to determine which (secret) groups they are both a member of. Group membership is kept secret to everybody else. Private handshaking is a more private form of secret handshaking, because it does not allow the group administrator to trace users. We extend the original definition of a handshaking protocol to allow and test for membership of multiple groups simultaneously. We present simple and efficient protocols for both the single group and multiple group membership case. Private handshaking is a useful tool for mutual authentication, demanded by many pervasive applications (including RFID) for privacy. Our implementations are efficient enough to support such usually resource constrained scenarios.
