互联网服务使得共享数字内容更快、更容易，但同时也提出了非法复制和分发这些数字内容的问题。许多公钥加密方案解决了这个问题。然而，秘密密钥没有被完全保护，即，这些种类的加密方法不能防止秘密密钥的非法复制和分发。在本文中，我们提出了一个混合加密方案，采用终端指纹。该方案是避免这种密钥滥用的模板，并且可以应用于例如基于属性的加密方案。终端指纹信息用于创建第二加密密钥和秘密密钥。由于终端指纹被假设为不可改变和不可知的，我们确保我们的秘密密钥是有效的，在终端中，这样的秘密密钥被创建。
Internet services make sharing digital contents faster and easier but raise an issue of illegal copying and distribution of those digital contents at the same time. A lot of public key encryption schemes solve this issue. However, the secret key is not completely protected i.e. these kinds of encryption methods do not prevent illegal copying and distribution of secret keys. In this paper, we propose a hybrid encryption scheme that employ terminal fingerprints. This scheme is a template to avoid such misuse of secret keys, and can be applied to, for example, attribute-based encryption schemes. There terminal fingerprint information is used to create a second encryption key and secret key. Since the terminal fingerprint is assumed to be unchangeable and unknowable, we ensure that our secret keys are valid in the terminal where such secret keys were created.
