摘要： An entropy source and a random number (RN) generator are disclosed. In one aspect, a low-energy entropy source includes a magneto-resistive (MR) element and a sensing circuit. The MR element is applied a static current and has a variable resistance determined based on magnetization of the MR element. The sensing circuit senses the resistance of the MR element and provides random values based on the sensed resistance of the MR element. In another aspect, a RN generator includes an entropy source and a post-processing module. The entropy source includes at least one MR element and provides first random values based on the at least one MR element. The post-processing module receives and processes the first random values (e.g., based on a cryptographic hash function, an error detection code, a stream cipher algorithm, etc.) and provides second random values having improved randomness characteristics.

摘要： An authentication method is provided between a device (e.g., a client device or access terminal) and a network entity. A removable storage device may be coupled to the device and stores a subscriber-specific key that may be used for subscriber authentication. A secure storage device may be coupled to the device and stores a device-specific key used for device authentication. Subscriber authentication may be performed between the device and a network entity. Device authentication may also be performed of the device with the network entity. A security key may then be generated that binds the subscriber authentication and the device authentication. The security key may be used to secure communications between the device and a serving network.

摘要： Disclosed is a method for transitioning a remote station from a current serving network node having an enhanced security context to a new serving network node. In the method, the remote station provides at least one legacy key, and generates at least one session key based on an information element associated with the enhanced security context. The remote station forwards a first message having the information element to the new serving network node. The remote station receives a second message, from the new serving network node, having a response based on either the legacy key or the session key. The remote station determines that the new serving network node does not support the enhanced security context if the response of the second message is based on the legacy key. Accordingly, the remote station protects communications based on the legacy key upon determining that the enhanced security context is not supported.
摘要翻译：公开了一种用于将远程站从具有增强的安全上下文的当前服务网络节点转换到新的服务网络节点的方法。在该方法中，远程站提供至少一个遗留密钥，并且基于与增强的安全上下文相关联的信息元素生成至少一个会话密钥。远程站将具有信息元素的第一消息转发到新的服务网络节点。远程站从新的服务网络节点接收具有基于传统密钥或会话密钥的响应的第二消息。如果第二消息的响应基于传统密钥，则远程站确定新的服务网络节点不支持增强的安全上下文。因此，当确定不支持增强的安全上下文时，远程站保护基于传统密钥的通信。

摘要： Transmitting devices facilitate privacy protection of content broadcasted from the transmitting device to a receiving device without the need to modify the receiving device. A transmitting device may be adapted to acquire content, such as audio and/or video data, to be broadcasted by the transmitter for reception and use by a receiving device. A transmission range is selected to define a distance for broadcasting the content from the transmission device for reception and use by a receiving device. A frequency is also selected to be used for broadcasting the content. With the transmission range and frequency selected, the transmitting device may broadcast the content according to the selected transmission range and frequency.

摘要： Conditional access to security-sensitive applications and/or content in a remote device may be granted based on a history of access to connectivity (e.g., access to a communication network) for the remote device. A remote device may monitor access to connectivity. If it is determined that the remote device has a first history to access to connectivity (e.g., a recent access to connectivity), a first security level is applied in providing access to the security-sensitive application. Otherwise, if a second history of access to connectivity is ascertained (e.g., no recent access to connectivity), a second security level is applied in providing access to the security-sensitive application, where the second security level is more stringent then the first security level. If the remote device is lost, a remote server may send a request to the remote device to restrict or disable access to the security-sensitive applications and/or content
摘要翻译：可以基于对远程设备的连接性（例如，访问通信网络）的访问历史来授予对远程设备中对安全敏感应用和/或内容的有条件访问。远程设备可能会监控连接的访问。如果确定远程设备具有访问连接的第一历史（例如，最近的连接访问），则在提供对安全敏感应用的访问时应用第一安全级别。否则，如果确定了连接连接的第二历史（例如，最近没有访问连接），则在提供对安全敏感应用的访问时应用第二安全级别，其中第二安全级别更严格，则第一安全级别水平。如果远程设备丢失，则远程服务器可以向远程设备发送请求以限制或禁止对安全敏感应用和/或内容的访问

摘要： A method, apparatus, and/or system are provided for establishing trust between an accessory device and a host device, using a global key known to both the host device and the accessory device, so that content protection for subscriber-based mobile broadcast services is provided. A secure link may be established between the accessory device and the host device so that when the accessory device receives encrypted content via a secured forward link only network, the accessory device may decrypt the content at the forward link only stack. The content is then re-encrypted/re-secured using one or more derived encryption keys and then sent to the host device where it may be decrypted and played back. A global key, unique to the particular device type of the host device, is employed to ultimately derive the session encryption keys used to re-encrypt/re-secure the content conveyed from the accessory device to the host device.

摘要： A system and method are provided that allow an application on a first terminal to inquire about available network communication associations that it can use to send data to another terminal, thereby avoiding the establishment of a new network communication association with the other terminal. A security information module may serve to collect and/or store information about available network communication associations between the first terminal and another terminal across different layers. The security information module may also assess a trust level for the network communication associations based on security mechanisms used to establish each association and/or past experience information reported for these network communication associations. Upon receiving a request for available network communication associations, the security information module provides this to the requesting application which can use it to establish communications with a corresponding application on the other terminal.

摘要： A block cipher is provided that secures data by encrypting it based on the memory address where it is to be stored. When encrypting data for storage in the memory address, the memory address is encrypted in a first plurality of block cipher rounds. Data round keys are generated using information from the first plurality of block cipher rounds. Data to be stored is combined with the encrypted memory address and encrypted in a second plurality of block cipher rounds using the data round keys. The encrypted data is then stored in the memory location. When decrypting data, the memory address is again encrypted as before while the encrypted stored data is decrypted in a second plurality of the block cipher rounds using the data round keys to obtain a partially decrypted data. The partially decrypted data is combined with the encrypted memory address to obtain fully decrypted data.
