摘要： A method and system to provide search results via a network is described. The method may comprise receiving a search request from a user including search criteria, searching cached World Wide Web documents to obtain a web result based on the search criteria, and searching for an associated document to obtain a restricted result based on the search criteria. The associated document may be associated with the user (e.g., the user may mark or otherwise identify the document after viewing it) and access to the associated document may be restricted. The web result and the restricted result may be communicated to the user for viewing via a web browser. In an example embodiment, the user may be provided via a web interface with an option to search the World Wide Web or a database including associated documents.

摘要： A computer-representable object (including, without limitation, a cryptographic key, or a graph or a Boolean description of a system) is secured using a generalized camouflaging technique. The secured object need not be stored in the system, not even in encrypted form. Instead, the technique employs a composition function that regenerates the secured object when one inputs a valid password (which may be any computer-representable information held by a user). By regenerating the secured object each time a valid password is entered, there is no need to store the secured object. If one inputs an invalid password, the technique may generate an incorrect object, such that the user is unable to distinguish this incorrect object from the secured object. If the user tries to use the incorrect object, the user can be exposed as unauthorized, without the user's knowledge that he has been exposed.

摘要： An exemplary method performed by a proxy server located between a content server and a client browser for reducing effects of network latency therebetween comprises intercepting a request from the client browser for a resource at the content server, obtaining a response by the content server to the request, determining that the response would, if unmodified, require a plurality of communications between the content server and the client browser in the absence of the proxy server, modifying the response to reduce a network latency associated with the plurality of communications for accessing information located externally to the response, and transmitting the modified response to the client browser for use thereby.

摘要： Techniques are disclosed for constructing web (or other networked) documents as parameterized forms of other networked documents. For example, a document may be represented as a collection of changes to be applied to a first document which is incorporated by reference in the second document. Instead of delivering the entire document over a slower network connecting the content server to the content browser, the document is delivered as a collection of changes to previously delivered documents that are much closer to the user's content browser. In an exemplary embodiment of the invention, special software is not necessarily required at the end user for reconstructing the second document from the set of base documents and the set of modifications to the base documents.

摘要： A digital wallet stores an cryptographically camouflaged access-controlled datum, e.g., a private key encrypted under the user's PIN. Entry of the correct PIN will correctly decrypt the stored key. Entry of certain pseudo-valid PINs will also decrypt the stored key, but improperly so, resulting in a candidate key indistinguishable from the correct key. Such pseudo-valid PINs are spread thinly over the space of PINs, so that the user is unlikely to realize a pseudo-valid PIN via a typographical error in entering the correct PIN. In existing wallet technologies, which lack pseudo-valid PINs, only the correct PIN produces a decrypted key; thus, hackers can find the correct PIN by entering all possible PINs until a key is produced. The present invention's plurality of candidate keys prevent a hacker from knowing when he has found the correct key. In addition, hacker detection may be moved off-line into devices accepting messages signed with candidate keys, and/or the lockout threshold may be increased. Thus, the wallet can be forgiving of typographic or transposition errors, yet a hacker trying large numbers of PINs will eventually guess a pseudo-valid (but still incorrect) PIN and recover a candidate private key whose fraudulent use will be detected. The wallet may be used with associated key generation, certification, and verification technologies. Such technologies may include pseudo-public keys embedded in pseudo-public certificates, i.e., public keys that are not generally known and which are contained in certificates that are verifiable only by entities so authorized by the certifying authority.

摘要翻译：使用广义伪装技术来确保计算机可表示的对象（包括但不限于密码密钥，或图形或系统的布尔描述）。安全对象不需要存储在系统中，甚至不加密形式。相反，该技术采用组合函数，当一个输入有效密码（其可以是用户持有的任何计算机可表示的信息）时，重新生成安全对象。每当输入有效的密码时，通过重新生成安全对象，就不需要存储安全对象。如果输入无效的密码，则该技术可能会生成不正确的对象，使得用户无法将此不正确对象与安全对象区分开。如果用户尝试使用不正确的对象，则用户可能会以未经授权的方式暴露，而无需用户知道他已被暴露。

摘要： A proxy implements automated version management of objects embedded in a document to eliminate/reduce network delays associated with requests to validate the objects in a browser (or other) cache. In an exemplary embodiment, the proxy obtains the document, assigns a unique URL to an embedded object, assigns an extended cache life to the object (via a header), updates the object's URL reference in the document, and sends the modified document to the user. When the user requests the object, the proxy obtains the object, attaches the new header, and transmits the object to the user. Because of its extended cache life, the object can subsequently be reused without time-consuming validation with the content server. In another embodiment, storage and validation of objects at the proxy (rather than at the cache) achieves reduced (and faster) validation while allowing refreshing prior to expiration.
摘要翻译：代理实现嵌入文档中的对象的自动版本管理，以消除/减少与在浏览器（或其他）缓存中验证对象的请求相关联的网络延迟。在示例性实施例中，代理获取文档，向嵌入对象分配唯一的URL，向对象（经由头）分配扩展的高速缓存生命周期，更新文档中的对象的URL引用，并将修改的文档发送到用户。当用户请求对象时，代理获取对象，附加新标题，并将对象发送给用户。由于其扩展的缓存使用寿命，随后可以重新使用该对象，而无需对内容服务器进行耗时的验证。在另一个实施例中，代理（而不是在高速缓存）上的对象的存储和验证实现了减少（和更快）的验证，同时允许在到期之前刷新。

摘要： A roaming user needing an his authentication credential (e.g., private key) to access a computer server to perform an electronic transaction may obtain the authentication credential in an on-demand fashion from a credential server accessible to the user over a computer network. In this way, the user is free to roam on the network without having to physically carry his authentication credential. Access to the credential may be protected by one or more challenge-response protocols involving simple shared secrets, shared secrets with one-to-one hashing, or biometric methods such as fingerprint recognition. If camouflaging is used to protect the authentication credential, decamouflaging may be performed either at the credential server or at the user's computer.

摘要： A method and system to protect web applications from malicious attacks is described. A stateful means of distinguishing between valid (e.g., harmless) and invalid (e.g., harmful) accesses is provided. A request from a content browser for content from an application server is forwarded by a firewall to the application server if it includes a URL that was previously transmitted from the application server. The firewall performs a security evaluation of the request if the URL of the request was not previously transmitted from the application server.
