During natural disasters or emergency situations, an essential requirement for an effective emergency management is the information sharing. In this paper, we present an access control model to enforce controlled information sharing during emergency situations. We also move this environment to cloud computing environment .Moving the data into cloud raises security issues like replay attacks, modification of the data which needs to be handled. So we use an encryption scheme namely attribute based encryption .Attribute based encryption encrypt the data based on the attributes of the users. The decryption of a ciphertext is possible only if the set of attributes of the user key matches the attributes of the ciphertext. A crucial security feature of Attribute-Based Encryption is collision-resistance. We extend our prototype to support break-glass policies which would allow the system to trace the violations of temporary access control policy.
