Abstract:In this paper, Confidential Data Security Methodology has been modified by using random key authority generation replacing two-party computation protocol to remove the disadvantage KEY ESCROW, with recent adoption and spreading of data sharing. One or more trusted parties supply information to decrypt ciphertext. Trusted parties are known as central authorities provide information in form of data recovery keys. Key escrow refers to the safeguarding of those data recovery keys. In this paper random key distribution in CP-ABE is explained and simulated to secure the confidential data. The definitive approach CP-ABE provides the addition of access policies and its updates. It has been demonstrated how to apply the proposed mechanism to securely and efficiently manage the confidential data distributed in the disruption-tolerant military network.

“…Recently introduced, Attribute-based Encryption (ABE) techniques [2,13,14] have drawn attention for realizing decentralized access control in large and dynamic networks and ubiquitous computing environments [8,15,16]. By allowing to implement an efficient targeted broadcast encryption, ABE provides means for designing flexible and scalable access control systems, without the need of administrating large access control policies.…”

Abstract. Attribute-based Encryption (ABE) allows for implementing fine-grained decentralized access control based on properties or attributes a user has. Thus, there is no need for writing detailed, user-based policies in advance. This makes ABE in particular interesting for implementing security mechanisms in dynamic environments such as ubiquitous computing, disaster management, or health-care. For supporting the latter two application areas, common ABE approaches lack one important feature: break-glass, i. e., the controlled overriding of access control restrictions.In this paper we present an integration of break-glass into an approach for end-to-end secure information sharing using ABE techniques.

SUMMARYInternet of Things (IoT) has been widely applied in various fields. IoT data can also be put to cloud, but there are still concerns regarding security and privacy. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is attracted attention in cloud storage as a suitable encryption scheme for confidential data share and transmission. In CP-ABE, the secret key of a user is associated with a set of attributes; when attributes satisfy the access structure, the ciphertext is able to be decrypted. It is necessary that multiple authorities issue and manage secret keys independently. Authorities that generate the secret key can be regarded as managing the attributes of a user in CP-ABE. CP-ABE schemes that have multiple authorities have been proposed. The other hand, it should consider that a user's operation at the terminals is not necessary when a user drop an attribute and key is updated and the design of the communication system is a simple. In this paper, we propose CP-ABE scheme that have multiple key authorities and can revoke attribute immediately with no updating user's secret key for attribute revocation. In addition, the length of ciphertext is fixed. The proposed scheme is IND-CPA secure in DBDH assumption under the standard model. We compare the proposed scheme and the other CP-ABE schemes and show that the proposed scheme is more suitable for cloud storage. key words: ciphertext-policy attribute-based encryption, multiple key authorities, attribute revocation, forward secrecy
