Decentralized Access Control

Decentralized Access Control

Decentralized Access Control java project report A new decentralized access management theme for secure knowledge storage in clouds that support anonymous authentication. During this theme, the cloud verifies the believability of the user while not knowing the user’s identity before storing knowledge and additionally has value-added the feature of access management during which solely valid users area unit ready to rewrite the hold on data. The theme prevents reply attack and supports creation, modification, and reading the information hold on within the cloud user and additionally has the address user revocation.

Moreover, our authentication and access management theme is decentralized and sturdy, in contrast to alternative access management schemes designed for clouds that area unit centralized. The communication, computation, and storage overheads area unit resembling centralized approaches. 

Conclusion

A decentralized access control technique with anonymous authentication, which provides user revocation and prevents replay attacks. The cloud does not know the identity of the user who stores information, but only verifies the user’s credentials. Key distribution is done in a decentralized way. Here using two Key approach attribute based encryption and attribute based signature. Attribute based encryption used CP-ABE (Cipher text – policy attribute based Encryption algorithm) and Attribute based Signature used the MD5. One limitation is that the cloud knows the access policy for each record stored in the cloud. In future, we would like to hide the attributes and access policy of a user.
