Overview
Intelligent Cryptosystems have advanced logic in their encryption/decryption mechanisms and provide more sophisticated control of data communications.
For example, each document can be encrypted with a decryption condition such as “only division directors or personnel division managers can decrypt it”. Through such advanced encryption/decryption mechanisms, Intelligent Cryptosystems will promote broader usage of cloud computing.
Features
- Users can share data securely in a cloud computing environment, because the data encryption and access control mechanisms are integrated.
- A user can encrypt data by specifying only a decryption condition, without specifying who can decrypt it.
- The decryption keys can be independently generated after the encryption process.
- Intelligent Cryptosystems are constructed efficiently and securely by using a new advanced mathematical methodology called “dual pairing vector spaces”.
Application scenarios
- Confidential data sharing in a company's systems
- Content delivery that has flexible access conditions
- Intelligent Cryptosystems were developed by NTT and Mitsubishi Electric Corporation and announced in a news release in July 2010.
