Grid Secure Scheme from Identity-Based Encryption using Random Oracle
The computing service and security service are separated in current Grid system, but the data transmission of the system have to cross unsafe public channel.This makes the results computing by the Grid system may be stolen or destroyed by artificial or non-artificial factors in transmission process.So the Grid system has secure requirements of confidential communication, data integrity and nonrepudiation.For these requirements, this paper puts forward an identity-based encryption scheme and realizes the function of confidentiality, Integrity, Key Update and non-repudiation.To test the security of the proposed scheme, the authors make a detailed analysis in random oracle model and prove the security of the scheme equivalents to the difficulty of the bilinear Diffle-Hellman problem.So our scheme is proved to be correct
