A combined announcement regarding the development of a new sophisticated encryption or fine grained encryption scheme has been announced by Nippon Telegraph and Telephone Corporation (NTT) and Mitsubishi Electric Corporation. The security risks in cloud computing can be possibly solved by this fine grained encryption scheme. The most sophisticated logic in the encryption decryption mechanism is achieved by this new encryption scheme. Therefore, sophisticated and fine-grained data transmission access control is enabled.
The recent popularity of cloud computing and other advanced network systems is due to the fast development of ICT. Confidential data is however transmitted via these networks to the servers for processing. Hence, as compared to the contemporary systems which make use of symmetric and public key encryption for network security, these networks demand higher security. A more advanced encryption scheme is therefore needed by these networks.
