Abstract: Protection of interpreted programming language code filesystem files from access and alteration may be provided by encrypting a file to be protected in a boot sequence. Run-time examination of a virtual appliance may be deterred by hiding the boot sequence in a restricted virtual appliance platform. No shell or filesystem access may be provided. Thus, permissions on a read-only filesystem (for example) may be kept from being altered. The permissions may be set along with filesystem access control lists to prevent unauthorized examination of the source files.

Abstract: A cipher engine performs cipher processing (encrypting/decrypting) on logical data streams in a physical data stream in a storage device. As the physical data stream changes from a first logical data stream to a second logical data stream, and the cipher engine switches from cipher processing the first logical data stream to the second logical data stream, cipher information of the first logical data stream is stored in a cipher state memory, cipher information of the second logical data stream is retrieved from the cipher state memory, and the cipher engine resumes cipher processing the second logical data stream using the cipher information of the second logical data stream. Advantageously, a virtually unlimited number of logical data streams is supported and duplicate cipher hardware is avoided.

Abstract: A compact secure data communication method is disclosed. In one embodiment, a compact security protocol provides cryptographic services on IP, UDP, and TCP packets with minimal bandwidth degradation due to encapsulation overhead. The disclosed protocol may be used, for example, in converged networks that carry both voice-over-IP and data traffic in and wireless networks, in which it is imperative to minimize per-packet overhead. The disclosed protocol provides as much security as possible, by authenticating the uncompressed headers rather than the compressed headers.

Abstract: When a user successfully logs into an account, the user is provided with a first-class login token, which entitles the user to one or more unsuccessful login attempts without experiencing delays the user would otherwise experience. If attempts with a second-class login token or an expired first-class login token is impermissible, a subsequent login attempt is subject to delays the user would otherwise not experience. The delays minimize the effectiveness of dictionary attacks. Additionally, if the user attempts to login without a login token or an invalid login token, the login attempt is impermissible and the user is provided with a second-class login token for use in a delayed, subsequent login attempt.

Abstract: Security keys for the provision of a secure service such as content provision are generated in an ancestral hierarchy, so that invalidation of a key in the hierarchy results in a need to reconfigure all other keys in the hierarchy to the extent they share common ancestry. When a user subscription to the service lapses, a decision on invalidation of their key is based in a determination of whether it's more costly to the subscriber to invalidate the key, or continue providing an unpaid-for service. Keys can be allocated to users from domains of the hierarchy on the basis of their economic value to the provider, with higher value users being allocated keys from domains which share fewer common ancestors with other users of other domains than those users share with each other, to minimize inconvenience to high value users of key reconfiguration.

Abstract: Provided are a method, system and article of manufacture for bidirectional data transfer. In certain embodiments a link layer login is sent from a first port to a second port. Subsequently, an application layer login is sent from the first port to the second port to establish a first data path, wherein the first data path is from the first port to the second port. Subsequently, another application layer login is sent from the second port to the first port to establish a second data path, wherein the second data path is from the second port to the first port. In certain other embodiments, a first data path is established from a first port to a second port. A determination is made at the first port, whether the second port has a second data path established from the second port to the first port. An application layer logout is sent from the first port to the second port, in response to determining that the second port has the second data path established from the second port to the first port.

Abstract: A method, apparatus, and computer instructions for process-based access controls on computer resources to processes. An access mechanism is provided in which a specific invoker obtains an object access identity (ACI). Another mechanism is provided in which a specific object, such as a file system resource, requires a specific object access identity to obtain one of the forms of access denoted by an access control list. A process may “grant” an identifier that is later “required” for a system resource access. Objects may specify their own access requirements and permitted access modes. The granted identifier, ACI, is stored in the process's credentials once these credentials match a specific “grant” entry in the access control list. This identifier has no meaning outside of being used to make an access decision for a specific resource. When a process tries to access the object, the object's access control list is scanned for “required” entries.

Abstract: A method and platform for maintaining the security of output data in an isolated execution environment. A system memory has an isolated output area readable only by secure output controllers having an isolated execution mode. The output controllers may make a request for access to the isolated output area, upon proper authentication if the request access is granted. The output device may either DMA the content of the isolated output area to an output end point, such as a display, or load it into local storage, the security of which is guaranteed by the controller.

Abstract: An approach for establishing secure multicast communication among multiple multicast proxy service nodes is disclosed. The multicast proxy service nodes, which can be distributed throughout an enterprise domain, are organized in a logical tree that mimics the logical tree arrangement of domains in a directory server system. The attributes of the multicast proxy service nodes include the group session keys that are members of the secure multicast or broadcast groups. Because keys as well as key version information are housed in the directory, multicast security can be achieved over any number of network domains across the entire enterprise. Key information is stored in, and the logical tree is supported by, a directory service. Replication of the directory accomplishes distribution of keys. Multicast proxy service nodes may obtain current key information from a local copy of the replicated directory.
