摘要： An approach is provided for managing data duplication in cloud computing. A method comprising, sending from a first device to a data center, data encrypted with a data encryption key for storing the encrypted data at the data center; encrypting the data encryption key according to an attribute-based encryption (ABE) scheme by using identity as an attribute in a deduplication policy for the data; issuing to a second device, a personalized secret attribute key which is derived from a public key of the second device according to the attribute-based encryption (ABE) scheme, wherein the personalized secret attribute key is to be used for decrypting the encrypted data encryption key at the second device, in combination with the policy.

摘要： Disclosed are devices, systems, and methods for securing data using attribute based data access. The data may correspond to a sensory environment, and the data is secured at the device. The device secures the data by segmenting the data into number of segments and defining an access policy, further submitting the access policy to a PKG of system for generating Access Tree having attributes at different level for accessing the data. These Access Trees are securely stored on the device using IBE mechanism. Further, the data after being secured, is uploaded to a system for analysis. At the system, an access request may be received for accessing the data. The access request further includes a request attribute, whereby the system verifies if the attribute satisfies the Access Policy. If the verification is positive, an access may be provided to the data accessor for accessing the data.

摘要： An input unit inputs a predicate which describes a plurality of selected elements being elements selected by a user. A predicate generation unit extracts two or more than two selected elements that are dependent on the same element in a higher layer, from the plurality of selected elements described in the predicate. Furthermore, the predicate generation unit reduces the number of elements described in the predicate by replacing a description of the two or more than two selected elements extracted with a description of the element in the higher layer.

摘要： Embodiments of a mobile device and method for secure online sign-up and provisioning of credentials for Wi-Fi hotspots are generally described herein. In some embodiments, provisioning occurs using a service set identifier (SSID) to associate with a hotspot and retrieve a virtual LAN (VLAN) identifier. The VLAN identifier is used to complete the signup and provisioning process. In some embodiments, a hotspot may implement a primary SSID and a dependent SSID. The mobile device associates with the hotspot using the dependent SSID to perform the secure online signup and provisioning process. Once credentials are obtained using the signup and provisioning process, the device can connect to the hotspot using the primary SSID and the already provisioned credentials. The provisioned credentials may include certificates, username/password, or SIM-type credentials.

摘要： Public key encryption methods and apparatus are provided for encrypting secret data under a public key in a data processing system (1). The secret data is provided as a message (m) comprising at least one element of a pair of base groups G1, G2 satisfying a bilinear map ê: G1×G2→GT where GT is a target group. The message (m) is encrypted using the public key to produce an encrypted message (c). A consistency component (v) is generated using the encrypted message (c) and the bilinear map whereby the consistency component (v) permits validation of the encrypted message without revealing the encrypted message. The output ciphertext (ct) comprises the encrypted message (c) and the consistency component (v).
