20080222697 | Application Server Object-level Security for Distributed Computing Domains - Objects on application servers may be defined into classes which receive different levels of security protection, such as definition of user objects and administrative objects. Domain-wide security may be enforced on administrative objects, which user object security may be configured separately for each application server in a domain. In a CORBA architecture, IOR's for shared objects which are to be secured on a domain-wide basis, such as administrative objects, are provided with tagged components during IOR creation and exporting to a name server. Later, when the IOR is used by a client, the client invokes necessary security measures such as authentication, authorization and transport protection according to the tagged components. | 09-11-2008 |
20080320112 | Highly scalable and highly available cluster system management scheme - A cluster system is treated as a set of resource groups, each resource group including a highly available application and the resources upon which it depends. A resource group may have between 2 and M data processing systems, where M is small relative to the cluster size N of the total cluster. Configuration and status information for the resource group is fully replicated only on those data processing systems which are members of the resource group. A configuration object/database record for the resource group has an associated owner list identifying the data processing systems which are members of the resource group and which may therefore manage the application. A data processing system may belong to more than one resource group, however, and configuration and status information for the data processing system is replicated to each data processing system which could be affected by failure of the subject data processing system—that is, any data processing system which belongs to at least one resource group also containing the subject data processing system. The partial replication scheme of the present invention allows resource groups to run in parallel, reduces the cost of data replication and access, is highly scalable and applicable to very large clusters, and provides better performance after a catastrophe such as a network partition. | 12-25-2008 |

20090138951 | Dynamic Cache Lookup Based on Dynamic Data - A system and method for tracking user security credentials in a distributed computing environment. The security credentials of an authenticated user includes not just his unique user identifier, but also a set of security attributes such as the time of authentication, the location where the user is authenticated (i.e., intranet user v. internet user), the authentication strength, and so on. The security attributes are used in access control decisions. The same user can be given different authorization if he has a different security attribute value. Security credentials may be generated either by WebSphere security code or by third party security provider code. This invention stores the user credentials in a distributed cache and provides a system and method to compute the unique key based on the dynamic security credentials for cache lookup | 05-28-2009 |
20090313470 | Using a Portable Computing Device as a Smart Key Device - A first data processing system, which includes a first cryptographic device, is communicatively coupled with a second data processing system, which includes a second cryptographic device. The cryptographic devices then mutually authenticate themselves. The first cryptographic device stores a private key of a first asymmetric cryptographic key pair and a public key of a second asymmetric cryptographic key pair that is associated with the second data processing system. The second cryptographic device stores a private key of the second asymmetric cryptographic key pair and a public key of the first asymmetric cryptographic key pair that is associated with the first data processing system. In response to successfully performing the mutual authentication operation between the two cryptographic systems, the first data processing system is enabled to invoke sensitive cryptographic functions on the first cryptographic device while the first data processing system remains communicatively coupled with the second data processing system. | 12-17-2009 |
20090327763 | Method for Using a Compact Disk as a Smart Key Device - A data processing method accepts a removable storage media, which becomes electrically engaged with a system unit within the data processing system, after which the removable storage media and the hardware security unit mutually authenticate themselves. The removable storage media stores a private key of a first asymmetric cryptographic key pair and a public key of a second asymmetric cryptographic key pair that is associated with the hardware security unit, and the hardware security unit stores a private key of the second asymmetric cryptographic key pair and a public key of the first asymmetric cryptographic key pair that is associated with the removable storage media. In response to successfully performing the mutual authentication operation between the removable storage media and the hardware security unit, the system unit is enabled to invoke cryptographic functions on the hardware security unit while the removable storage media remains engaged with the system unit. | 12-31-2009 |
20140208119 | Controlling Exposure of Sensitive Data and Operation Using Process Bound Security Tokens in Cloud Computing Environment - Exposure of sensitive information to users is controlled using a first security token containing user identity and user credentials to represent the user who requests services, and a second security token containing two other identities, one identifying the token issuer and the other identifying the owning process. When requesting services, the token-owning process sends a security token to indicate who is making the request, and uses its key to digitally sign the request. The token-owning process signs the request to indicate that it endorses the request. A receiving server accepts a request if (1) the token-owning process endorses the request by signing the request; (2) the token is valid (token is signed by its issuer and the digital signature is verified and unexpired); (3) user entity, which can be a real user or a deployment or a server process, that is represented by the token has the authorization to access the specified resources; and (4) the token-owning process is authorized to endorse the user entity represented by the token to access the specified resources. | 07-24-2014 |
20140317716 | Extending infrastructure security to services in a cloud computing environment - A cloud deployment appliance (or other platform-as-a-service (IPAS) infrastructure software) includes a mechanism to deploy a product as a “shared service” to the cloud, as well as to enable the product to establish a trust relationship between itself and the appliance or IPAS. The mechanism further enables multiple products deployed to the cloud to form trust relationships with each other (despite the fact that each deployment and each product typically, by the nature of the cloud deployment, are intended to be isolated from one another). In addition, once deployed and provisioned into the cloud, a shared service can become part of a single sign-on (SSO) domain automatically. SSO is facilitated using a token-based exchange. Once a product registers with a token service, it can participate in SSO. This approach enables enforcement of consistent access control policy across product boundaries, and without requiring a user to perform any configuration. | 10-23-2014 |
20150074395 | Establishing a Trust Relationship Between Two Product Systems - A mechanism is provided for establishing a trust relationship between two products. A resource device receives a registration request from an application device to access a resource on the resource device by an application and users of the application on the application device. The resource device sends a registration response using a redirection uniform resource identifier (URI) provided with the registration request, where the registration response includes an authorization code and a symmetric key in response to authenticating the registration request. The resource device receives an access token request that includes the symmetric key, verifiable authentication data, and the redirection URI. The resource device sends an access token to the application device in response to validating the access token request, where the access token allows for access to the resource on the resource device thereby establishing the trust relationship between the resource device and the application device. | 03-12-2015 |
