A Model For Secure Data Sharing Using Attribute Based Encryption
The data security concerns and requirements are very essential for social networks or for cloud computing where individuals, organizations, and businesses may outsource their various types of data, including highly sensitive data into the cloud. Always people would like to make their sensitive or private data only accessible to authorized people having some access policies. So in order to share...
متن کاملAn Adaptively CCA-Secure Ciphertext-Policy Attribute-Based Proxy Re-Encryption for Cloud Data Sharing
A Ciphertext-Policy Attribute-Based Proxy Re-Encryption (CP-ABPRE) employs the PRE technology in the attribute-based encryption cryptographic setting, in which the proxy is allowed to convert an encryption under an access policy to another encryption under a new access policy. CP-ABPRE is applicable to many real world applications, such as network data sharing. The existing CP-ABPRE systems, ho...
متن کاملAttribute Based Encryption Schemes for Efficient Verifiable Data Sharing
Attribute-based encryption (ABE) with outsourced decryption not only enables finegrained sharing of encrypted data, but also overcomes the effective drawback of the standard ABE schemes. An Attribute based encryption scheme with outsourced decryption allows a third party (e.g., a cloud server) to renovate an ABE cipher text into a (short) El Gamal-type cipher text using a public transformation ...
متن کاملSecure Outsourced Attribute-based Encryption
Attribute-Based Encryption (ABE) is a promising cryptographic primitive which significantly enhances the versatility of access control mechanisms. Due to the high expressiveness of ABE policies, the computational complexities of ABE key-issuing (by Attribute Authorities (AAs)) and decryption (by eligible users) are getting prohibitively high. Despite that the existing Outsourced ABE solutions a...
متن کاملSecure Sharing of Health Information in Cloud System Using Attribute-Based Encryption
Personal health record (PHR) is an emerging patient-centric model of health information exchange, which is often outsourced to be stored at a third party, such as cloud providers. However, there have been wide privacy concerns as personal health information could be exposed to those third-party servers and to unauthorized parties. To assure the patients’ control over access to their own PHRs, i...
