摘要： A vehicle data archive system is provided. An instrumentation interface receives at least one sensory data signal of the vehicle. A memory stores the at least one sensory data signal. A first transponder responds to a periodic provider signal of a trusted third party (TTP)/service provider for creating a corresponding shared encryption key, which is used to generate a digital signature from the stored data, the signature may be stored with the data or returned to the TTP/service provider. The signature is used to authenticate the data stored in the archive system. The encryption value used to generate the signature may be stored locally in the data archive or obtained from the TTP/service provider. The data in the data archive may also be stored without encryption. The system also allows an authorized user to delete a portion of the stored encrypted sensory data.
摘要翻译：提供车辆数据存档系统。仪器接口接收车辆的至少一个感觉数据信号。存储器存储至少一个感觉数据信号。第一应答器响应可信第三方（TTP）/服务提供商的周期性提供商信号，用于创建相应的共享加密密钥，该密钥用于从存储的数据生成数字签名，签名可以与数据一起存储，或者返回给TTP /服务提供商。签名用于对存档系统中存储的数据进行身份验证。用于生成签名的加密值可以本地存储在数据存档中或从TTP /服务提供商获得。数据存档中的数据也可以不加密地存储。该系统还允许授权用户删除存储的加密感觉数据的一部分。

摘要： An electronic shelf label (ESL) transmits a negative response to a radio relay station by means of weak radio waves if it failed to normally receive price information. On the other hand, the ESL transmits no response if it failed to normally receive both ID information and price information. The radio relay station transmits to a radio communication base station ID information of the ESL which transmitted no response and ID information of the ESL which transmitted the negative response. The radio communication base station transfers the received ID information to an electronic shelf label (ESL) server. The ESL server re-transmits via the radio communication base station information to the ESL which transmitted no response and the ESL which transmitted the negative response.
摘要翻译：电子货架标签（ESL）如果无法正常接收价格信息，则通过弱无线电波向无线电中继站发送否定响应。另一方面，如果无法正常接收ID信息和价格信息，则ESL不传送响应。无线电中继站向发送无响应的ESL的无线通信基站ID信息和发送了否定响应的ESL的ID信息进行发送。无线电通信基站将接收到的ID信息传送到电子货架标签（ESL）服务器。 ESL服务器通过无线电通信基站信息重传到不发送响应的ESL和发送负反应的ESL。
