    摘要: Digital assets are in a secured form that only those with granted access rights can access. Even with the proper access privilege, when a secured file is classified, at least a security clearance key is needed to ensure those who have the right security clearance can ultimately access the contents in the classified secured file. According to one embodiment, a secured file or secured document includes two parts: a header, and an encrypted data portion. The header includes security information that points to or includes access rules, a protection key and a file key. The access rules facilitate restrictive access to the encrypted data portion and essentially determine who the secured document can be accessed. The file key is used to encrypt/decrypt the encrypted data portion and protected by the protection key. If the contents in the secured file are classified, the file key is jointly protected by the protection key as well as a security clearance key associated with a user attempting to access the secured file.

    摘要翻译: 数字资产是一种安全的形式,只有具有授权访问权限的用户才能访问。 即使具有正确的访问权限,当安全文件被分类时,至少需要一个安全许可密钥,以确保那些具有正确安全许可的用户可以最终访问分类的安全文件中的内容。 根据一个实施例,安全文件或安全文档包括两部分:头部和加密数据部分。 标题包括指向或包括访问规则的安全信息,保护密钥和文件密钥。 访问规则有助于对加密数据部分的限制性访问,并且基本上确定可以访问安全文档的身份。 文件密钥用于加密/解密加密数据部分并受保护密钥保护。 如果安全文件中的内容被分类,则文件密钥由保护密钥以及与尝试访问安全文件的用户相关联的安全许可密钥共同保护。

    摘要: With files secured by encryption techniques, keys are often required to gain access to the secured files. Techniques for providing and using multiple levels of keystores for securing the keys are disclosed. The keystores store keys that are needed by users in order to access secured files. The different levels of keystores offer compromises between security and flexibility/ease of use.

    摘要: An improved system and approaches for protecting secured files when being used by an application (e.g., network browser) that potentially transmits the files over a network to unknown external locations are disclosed. According to one aspect, access to secured files is restricted so that unsecured versions of the secured files are not able to be transmitted over a network (e.g., the Internet) to unauthorized destinations. In one embodiment, processes operating on a computer system are monitored to determine destination locations, if any, of said processes, and then using such destination locations to determine whether to permit the processes to open files in a secure or unsecured manner.

    摘要: A system includes a server with an access manager configured to restrict access to files of an organization and maintain at least encryption keys for internal and external users and an external access server connected to the server and coupled between the server and a data network. The data network is configured to allow the external users use of the external access server. The external access server is also configured to permit file exchange between the internal users and the external users via the server.

    摘要: Even with proper access privilege, when a secured file is classified, at least security clearance (e.g. a clearance key) is needed to ensure those who have the right security clearance can ultimately access the contents in the classified secured file. According to one embodiment, referred to as a two-Opronged access scheme, a security clearance key is generated and assigned in accordance with a user's security access level. A security clearance key may range from most classified to non-classified. Depending on implementation, a security clearance key with a security level may be so configured that the key can be used to access secured files classified at or lower than the security level or multiple auxiliary keys are provided when a corresponding security clearance key is being requested. The auxiliary keys are those keys generated to facilitate access to secured files classified respectively less than the corresponding security or confidentiality level.

    摘要: Techniques and mechanisms for controlling copying of content from a secured file or secured document are disclosed. In one embodiment, the techniques or mechanisms operate to control clipboard usage such that content from a secured document of one application is not able to be copied to another application or a different document of another application by way of a clipboard. According to another embodiment, alternate content is copied to another application or a different document of another application instead of the content from the secured document.

    摘要: Techniques for dynamically altering security criteria used in a file security system are disclosed. The security criteria pertains to keys (or ciphers) used by the file security system to encrypt electronic files to be secured or to decrypt electronic files already secured. The security criteria can, among other things, include keys that are required to gain access to electronic files. Here, the keys can be changed automatically as electronic files transition between different states of a process-driven security policy. The dynamic alteration of security criteria enhances the flexibility and robustness of the security system. In other words, access restrictions on electronic files can be dependent on the state of the process-driven security policy.

    摘要翻译: 公开了用于动态改变文件安全系统中使用的安全标准的技术。 安全标准涉及文件安全系统用于加密要保护的电子文件或解密已经保护的电子文件的密钥(或密码)。 安全标准可以包括访问电子文件所需的密钥。 这里,随着电子文件在进程驱动的安全策略的不同状态之间转换,密钥可以自动更改。 安全标准的动态改变增强了安全系统的灵活性和鲁棒性。 换句话说,对电子文件的访问限制可以取决于进程驱动的安全策略的状态。
