    • Methods and apparatuses for providing DRM interoperability are provided. Proxy re-encryption technique using bilinear map is used, and the same content can be used in different devices. According to the method of providing DRM interoperability includes in proxy agent with respect to digital rights management (DRM) service providers and device which supports predetermined DRM, first DRM service provider, second DRM service provider, the proxy agent, and the device identify each other, and proxy re-encrypt an interoperable content (IC) and provide the IC to the device. The IC is second-level encrypted by using a key of the first DRM service provider, and the proxy re-encryption is performed by using a proxy key generated from proxy key information provided from the first DRM service provider and the second DRM service provider. Therefore, a problem in which interoperability cannot be guaranteed since a DRM technique depends on a service provider is resolved.
    • 提供了提供DRM互操作性的方法和设备。 使用双线性映射的代理重新加密技术,相同的内容可以在不同的设备中使用。 根据提供DRM互操作性的方法,其包括关于数字权限管理(DRM)服务提供商的代理代理和支持预定DRM的设备,第一DRM服务提供商,第二DRM服务提供商,代理代理和设备彼此识别 ,并且代理重新加密可互操作的内容(IC)并将IC提供给设备。 IC通过使用第一DRM服务提供商的密钥进行二级加密,并且通过使用从第一DRM服务提供商和第二DRM服务提供商提供的代理密钥信息生成的代理密钥来执行代理重新加密。 因此,解决了DRM技术取决于服务提供商的互操作性不能保证的问题。

    • A secondary battery includes an electrode assembly, an open-topped can accommodating the electrode assembly, and a cap assembly sealing the can. The electrode assembly includes a positive electrode plate having a positive electrode coated portion and positive electrode non-coating portions, a negative electrode plate having a negative electrode coated portion and negative electrode non-coating portions, and a separator interposed between the positive and negative electrode plates and wound with the electrode plates. The positive electrode non-coating portion has a region where the height of the positive electrode non-coating potion is lower than that of the positive electrode coating portions.
    • 二次电池包括电极组件,容纳电极组件的敞开的顶盖,以及密封罐的盖组件。 电极组件包括具有正极涂覆部分和正极非涂覆部分的正极板,具有负极涂覆部分和负极非涂覆部分的负极板以及介于正极和负极之间的隔板 并用电极板缠绕。 正极未涂布部分具有正极未涂覆部分的高度低于正极涂覆部分的高度的区域。
