摘要： Mobile device assisted secure computer network communications embodiments are presented that employ a mobile device (e.g., a mobile phone, personal digital assistant (PDA), and the like) to assist in user authentication. In general, this is accomplished by having a user enter a password into a client computer which is in contact with a server associated with a secure Web site. This password is integrated with a secret value, which is generated in real time by the mobile device. The secret value is bound to both the mobile device's hardware and the secure Web site being accessed, such that it is unique to both. In this way, a different secret value is generated for each secure Web site accessed, and another user cannot impersonate the user and log into a secure Web site unless he or she knows the password and possesses the user's mobile device simultaneously.
摘要翻译：提出了使用移动设备（例如，移动电话，个人数字助理（PDA）等）的移动设备辅助的安全计算机网络通信实施例来协助用户认证。一般来说，这是通过使用户将密码输入到与与安全网站相关联的服务器联系的客户端计算机来实现的。这个密码是与移动设备实时生成的秘密值集成的。秘密值绑定到移动设备的硬件和被访问的安全网站，这两者都是唯一的。以这种方式，为所访问的每个安全网站生成不同的秘密值，而另一个用户不能模拟用户并登录到安全网站，除非他或她知道密码并同时拥有用户的移动设备。

摘要： Systems and methods provide a content encryption schema for integrating digital rights management (DRM) in a multicast/broadcast encryption system. In one implementation, an exemplary integrated key schema provides content encryption keys that can be employed by a multicast or broadcast process, while providing DRM protection of recorded multicast content via a single DRM decryption secret. The integrated key schema provides high security and allows encrypted multicast content to be saved directly to local files. A license server can efficiently manage and generate DRM keys to be delivered to clients because only a single key needs to be delivered per license to a client. The integrated key schema can be applied together with conventional broadcast or multicast encryption techniques.

摘要： Key management is performed to generate a single key allowing of the decoding of all authorized levels of a plurality of access types within a scalable codestream. An access node set is derived from sets representing access types having hierarchies representable by fully ordered sets, such as resolution and layer levels, and hierarchies representable by partially ordered sets, such as tile and precinct levels. The access node set derived is a partially ordered set representing the combinations of levels of the access types included within the codestream. A hierarchical key management system is applied to the access node set to assign a key to each of the access nodes, generate content encryption keys, and encrypt the codestream. A client receiving the codestream, access node set, and other public information uses the key to derive additional keys to decrypt the codestream.

摘要： Systems and methods configured for recoding an odd integer and elliptic curve point multiplication are disclosed, having general utility and also specific application to elliptic curve point multiplication and cryptosystems. In one implementation, the recoding is performed by converting an odd integer k into a binary representation. The binary representation could be, for example, coefficients for powers of two representing the odd integer. The binary representation is then configured as comb bit-columns, wherein every bit-column is a signed odd integer. Another implementation applies this recoding method and discloses a variation of comb methods that computes elliptic curve point multiplication more efficiently and with less saved points than known comb methods. The disclosed point multiplication methods are then modified to be Simple Power Analysis (SPA)-resistant.

摘要： A flexible framework for generating “scalable layered access” codestreams allows a bitstream architect to select the number of access types and the number of access layers within each access type. At least some of the access layers are encrypted (or scrambled). Some of the access layers may be left unencrypted or unscrambled to allow free access to those layers. The framework facilitates simultaneous access of multimedia content by different users enjoying selective decryption of different access types and different access layers. An exemplary key schema for the framework sends only one or only a few keys to an end user for a given access layer, from which decryption keys for the content can be derived by hashing and then combining under a Group Diffie-Hellman key agreement. In one implementation, only one key is sent in a license to an end user and other partial key information for Group Diffie-Hellman combination with the licensed key is included in the publicly distributed codestream.
摘要翻译：用于生成“可分级分层访问”码流的灵活框架允许比特流架构师选择每种访问类型中的访问类型的数量和访问层数。至少一些接入层被加密（或加扰）。一些访问层可以保持未加密或解扰，以允许对这些层的自由访问。该框架便于不同用户同时访问多媒体内容，享受不同接入类型和不同接入层的选择性解密。用于框架的示例性关键模式仅向给定访问层的最终用户发送一个或仅几个密钥，通过散列然后根据Group Diffie-Hellman密钥协议来组合内容的解密密钥。在一个实现中，只有一个密钥在许可证中发送给最终用户，并且用于具有许可密钥的组Diffie-Hellman组合的其他部分密钥信息被包括在公开分发的码流中。
