摘要： An individualized time -to-live (TTL) is determined for a reputation score of a computer file. The TTL is determined based on the reputation score and the confidence in the reputation score. The confidence can be determined based on attributes such as the reputation score, an age of the file, and a prevalence of the file. The reputation score is used to determine whether the file is malicious during a validity period defined by the TTL, and discarded thereafter.
摘要翻译：针对计算机文件的信誉分数确定个性化的生存时间（TTL）。 TTL是根据信誉评分和信誉评分的信心确定的。信心可以根据诸如信誉评分，文件的年龄以及文件的普遍性等属性来确定。信誉分数用于确定在由TTL定义的有效期内文件是否恶意，之后丢弃。

摘要： To prevent gaming of a reputation system, a security token is generated for a security module using metadata about the client observed during the registration of the security module. The registration server selects metadata for use in generating the security token. The generated security token is provided to identify the client in later transactions. A security server may conduct a transaction with the client and observe metadata about the client during the transaction. The security server also extracts metadata from the security token. The security server correlates the observed metadata during the transaction with the extracted metadata from the security token. Based on the result of the correlation, a security policy is applied. As a result, the metadata in the security token enables stateless verification of the client.
摘要翻译：为了防止信誉系统的游戏，使用在安全模块注册期间观察到的关于客户端的元数据，为安全模块生成安全令牌。注册服务器选择用于生成安全令牌的元数据。提供的生成的安全令牌用于在稍后的事务中标识客户机。安全服务器可以与客户进行交易，并在交易期间观察有关客户端的元数据。安全服务器还从安全令牌中提取元数据。安全服务器将事务期间观察到的元数据与来自安全令牌的提取的元数据相关联。基于相关性的结果，应用安全策略。因此，安全令牌中的元数据使客户端能够进行无状态验证。

摘要： Reputations of objects are determined by a reputation system using reports from clients identifying the objects. Confidence metrics for the clients are generated using information determined from the reports. Confidence metrics indicate the amounts of confidence in the veracity of the reports. Reputation scores of objects are calculated using the reports from the clients and the confidence metrics for the clients. Confidence metrics and reputation scores are stored in correlation with identifiers for the objects. An object's reputation score is provided to a client in response to a request.

摘要： Different targets (c 0 , N 1 ) of a digital certificate are mapped into a "super-target" using methods allowing a certificate validity verifier (110) to compute the super-target. The certificate includes the super-target instead of the targets. Also, a certificate with multiple targets can be signed with a redactable signature by the certification authority (CA 120). When the certificate's owner provides the certificate to a verifier together with a validity proof, the owner redacts the certificate to delete unnecessary targets. A single validity proof (c i (F)) may be provided to certificate owners for a set (F) of the certificates via a multicast transmission if a multicasting group (2010) is formed to correspond to the set. A verifier (110) may decide to cache the validity proof for a set provide the cached proof to other parties. The caching decision is based on the caching priority of the set F. The priority may depend on the number of certificates in the set F, the sum of the remaining validity periods for the certificates in the set, and other factors. In the setup phase, the CA generates validation proof data structures for greater time than the maximum validity period of any certificate. Therefore, new certificates can be added to the existing data structures after the setup phase. A distributed certificate authority includes a CA and a number of Sub-CAs (2610). The Sub-CAs have secret certificate validation data, but different data are provided to different Sub-CAs for each certificate. If a Sub-CA is compromised, the Sub-CA validity proof will be withheld by the CA to alert the verifiers not to use the data from this Sub-CA. Also, the secret data are encrypted when distributed to the Sub-CAs. A decryption key (DK.j.k) for each "partition" of time is distributed to each Sub-CA at or shortly before the start of the partition. A compromised Sub-CA can be reactivated at the end of the partition because the adversary does not get the decryption keys for the future partitions.

摘要： A method and apparatus for obtaining access to services of service providers. In one embodiment, the method comprises requesting a desired service through a foreign service provider.(101), generating a hash tree and generating a digital signature on a root value of the hash tree (102), sending the digital signature and the root value to the foreign service provider (103), providing one or more tokens to the foreign service provider with the next packet if the foreign service provider accepts the signature (105) and continuing to use the service while the foreign service provider accepts token (107).
