安全列表解码

Secure list decoding

Masahito Hayashi

摘要:

我们提出了一个新的安全列表解码的概念。虽然传统的列表解码要求列表包含发送的消息,但安全列表解码要求以下附加的安全条件。第一附加安全条件是不可能正确解码,即,接收机不能唯一地识别所发送的消息,即使所发送的消息包含在列表中。当传输速率大于信道容量时,可以很容易地满足该条件。另一个附加的安全条件是发送方不可能估计解码列表中除了发送的消息之外的另一个元素。该协议可用于匿名拍卖,实现了投标的匿名性。

英文摘要:

We propose a new concept of secure list decoding. While the conventional list decoding requires that the list contains the transmitted message, secure list decoding requires the following additional security conditions. The first additional security condition is the impossibility of the correct decoding, i.e., the receiver cannot uniquely identify the transmitted message even though the transmitted message is contained in the list. This condition can be trivially satisfied when the transmission rate is larger than the channel capacity. The other additional security condition is the impossibility for the sender to estimate another element of the decoded list except for the transmitted message. This protocol can be used for anonymous auction, which realizes the anonymity for bidding.
