Abstract

Traditional cryptography system shares the keys between senders and receivers for encryption and decryption purpose to achieve the data security, where these key sharing was done through the certificate exchange and signature storage. But it did not scale well as number of users get increased key distribution and signature storage was the great challenge. To overcome this problem of traditional cryptography system Identity Based Encryption has been proposed, where instead of IDs itself were used for encryption, which again leads to the limitation of only one-to-one communication was possible. To solve this problem multicast communication can be made possible through the Attribute Based Encryption. Single mediator and key policy ABE was used, which was not so efficient and failed for providing revocation. So MAMM concept with CP-ABE was proposed which gives more security by multiple encryptions through hierarchical mediators. This system can be extended for the distributed system, where more security can be given to the data by using MAMM with CP-ABE in distributed environment.
