    Abstract: Some embodiments of the invention provide a method of verifying the integrity of digital content. At a source of the digital content, the method generates a signature for the digital content by applying a hashing function to a particular portion of the digital content, where the particular portion is less than the entire digital content. The method supplies the signature and the digital content to a device. At the device, the method applies the hashing function to the particular portion of the digital content in order to verify the supplied signature, and thereby verifies the integrity of the supplied digital content.

    Abstract translation: 本发明的一些实施例提供了一种验证数字内容的完整性的方法。 在数字内容的源头上,该方法通过对数字内容的特定部分应用散列函数来生成数字内容的签名,其中特定部分小于整个数字内容。 该方法将签名和数字内容提供给设备。 在该设备中,该方法将哈希函数应用于数字内容的特定部分,以验证所提供的签名,从而验证所提供的数字内容的完整性。
