在一些示例性实施例中，在第一感知数据为对第二感知数据进行加密得到，或者，第一感知数据为对第二感知数据进行加密和压缩处理得到的情况下，需要将第一感知数据对应的解密密钥通知感知数据的获取方，由于解密密钥数据量比较小，通过车联网广播传输即可，同时也实现了内容和密钥相分离，进一步提高了安全性；并且，为了将解密密钥和第一感知数据关联起来，边缘云服务器需要生成第一感知数据对应的流水号码，用于区分第一设备不同时间上传的第一感知数据，并通过基站发送给第一设备，第一设备在通过车辆网广播解密 密钥的同时，也广播流水号码；并且，为了边缘云服务器能够对第一感知数据进行相应的处理，需要将解密密钥通过基站发送给边缘云服务器，在将解密密钥发送给边缘云服务器时，为了提高安全性，需要通过安全传输通道将解密密钥通过基站发送给边缘云服务器。也就是说，通过网络切片将第一感知数据和对应的第一标识发送给基站后，该方法还包括：
