智能电网允许用户通过IP网络处理与用电有关的信息，从而保证信息的有效性和保密性。在我们未来的范围内，消费者使用的电费可能会通过智能电网向消费者自己收取，甚至在他们的家庭之外也是如此。这些信息严格涉及消费者的隐私，因此我们提出了一种智能电网用电的匿名认证协议。我们的主要思想是利用具有可控链接性的群签名。在这些群签名中，只有指定的签名者才能在单个群公钥下生成匿名性的数字签名，只有拥有链接密钥的实体才能区分签名是否由同一签名者生成。鉴于我们提出的协议能够包含任何具有可控链接性的群签名方案，我们还提出了新的带令牌的可控链接的群签名方案，并由智能电网上的智能电表来处理。
Smart Grid allows users to deal with information related to the electricity usage via IP networks, and then guarantee of both validity and privacy of information is necessary for users. In our future scope, the electricity bill used by consumers may be charged to the consumers themselves via the Smart Grid, even outside their homes. Such information is strictly related to privacy of consumers and hence we propose an anonymous authentication protocol for the electricity usage on the Smart Grid. Our main idea is to utilize group signatures with controllable linkability. In these group signatures, only designated signers can generate digital signatures with anonymity under a single group public key, and only entities with a link key can distinguish whether the signatures are generated by a same signer or not. Whereas our proposed protocol is able to include any group signature scheme with controllable linkability, we also propose new controllably linkable group signatures with tokens, which are handled by smart meters on the Smart Grid.
