TOKYO -- Nippon Telegraph and Telephone Corporation (NYSE:NTT - News)("NTT") and Mitsubishi Electric Corporation (TOKYO:6503 - News)("Mitsubishi Electric") today announced that they have developed a new advanced encryption (fine-grained encryption) scheme expected to become a potential solution to the security risks in cloud computing. This new encryption scheme achieves the most advanced logic in the encryption-decryption mechanism, which enables sophisticated and fine-grained data transmission/access control.
The rapid development of information and communication technology has led to the recent spread of cloud computing and other advanced network systems. These networks, however, transmit private or confidential information to the server to process, which demands higher security than current systems that use symmetric and public key encryption to maintain network security. These advanced network systems therefore require a more sophisticated encryption scheme.
NTT and Mitsubishi Electric have successfully developed a new fine-grained encryption scheme with the most advanced logic as an encryption-decryption mechanism. This scheme, developed using a mathematical approach called the "dual pairing vector spaces," will allow network users to maintain highly confidential information encrypted even in cloud computing environments. This achievement will help expand cloud computing applications to fields where they could previously not be applied.
