摘要： Through the use of a one-time-use nonce, the transfer of cryptographic data over a potentially insecure link in a two-factor content protection system is avoided. The nonce may be stored encrypted with a public key from a smart card. A random key may be used to produce a storage key, which is used to encrypt a content protection key. The random key may be stored, encrypted with a key derived from the nonce. Instead of receiving a raw content protection key over the potentially insecure link, the raw nonce is received and, once used, replaced with a new nonce.
摘要翻译： 通过使用一次性使用的随机数，可避免在双因素内容保护系统中的潜在不安全链路上的密码数据传输。 可以使用来自智能卡的公开密钥来存储该随机数。 可以使用随机密钥来产生用于加密内容保护密钥的存储密钥。 随机密钥可以使用从随机数导出的密钥进行加密。 而不是在潜在不安全的链接上接收到原始内容保护密钥，而是接收到原始的随机数，并且一旦被使用，就被替换为新的随机数。

摘要： Rather than storing all data in the same manner, e.g., an encrypted manner, a security level with which to associate received data of a given type may be determined. Subsequently, distinct types of data may be stored in a distinct manner, with the manner of storage having a security level appropriate to the type of data. For example, a first type of data may be stored in an encrypted manner (i.e., with a high level of security), while a second level of data may be stored in a plain text manner (i.e., with a low level of security).
摘要翻译： 可以确定与给定类型的接收数据相关联的安全级别，而不是以相同方式存储所有数据，例如加密方式。 随后，不同类型的数据可以以不同的方式存储，存储的方式具有适合数据类型的安全级别。 例如，可以以加密的方式（即，具有高安全级别）来存储第一类型的数据，而可以以纯文本方式（即，具有低安全级别）来存储第二级数据） 。

摘要： A communication system can provide one or more mechanisms for controlling data transfer on a mobile device. A technique based on such a mechanism includes receiving a request to transfer data to an application, accessing a first service identifier associated with the data, accessing a second service identifier associated with a service mode of the application, and determining whether to allow a transfer of the data to the application based on the first service identifier and the second service identifier.
