oracle
We also give an ID-based deniable ring authentication based on bilinear pairings, which is proved to be secure in the random oracle model.
      
A relational database has been formed under the control of the Database Management System (DBMS) Oracle 8.
      
Most importantly, the proposed scheme has been proven to be tightly semantically secure under adaptive chosen ciphertext attacks (IND-CCA2) and to provide integrity of ciphertext (INT-CTXT) as well as non-repudiation in the random oracle model.
      
We also prove that our scheme is chosen message and ID secure in the random oracle model, assuming the hardness of factoring.
      
This letter presents an anonymous off-line electronic payment model with multiple issuing-banks and gives an implementation scheme based on the discrete logarithm problem and the random oracle model.
      
Both schemes are proven to be secure against adaptive chosen message attack in the random oracle model under the normal security notions with the assumption that the Computational Diffie-Hellman problem is hard in the m-torsion groups.
      
This paper discusses the designing plan of ORACLE-based Bohai Sea engineering geology database structure from requisition analysis, conceptual structure analysis, logical structure analysis, physical structure analysis and security designing.
      
Based on the ArcGIS geographic information system and the ORACLE database management system, this paper reports our studies on the technology of Marine Engineering Geological Exploration Information System (MEGEIS).
      
The use of a study-oriented LIMS with an Oracle data-base reduced pre-and post-run data handling and data storage activity and thus facilitated management of the large amount of analytical data generated.
      
It aims to achieve interoperability among Oracle, Sybase and other different DMBSs through the registration of these DBMSs to Panorama and through the single global query language-PanoSQL designed for this system.
      
Then, as an example, we present the registration of Oracle to panorama in order to achieve interoperability in this system.
      
In the random oracle model, we also carry out the strict security proof for the proposed scheme.
      
The security of the proposed scheme is not loosely related to the discrete logarithm assumption but tightly related to the decisional Diffie-Hellman assumption in the random oracle model.
      
In this paper, we lower the upper bound of the number of solutions of oracle transformation polynomialF(x) overGF(q).
      
In this paper, we present an efficient and practical threshold bind signature from Weil pairing on super-singular elliptic curves or hyper-elliptic curves over finite field and prove that our scheme is provably secure in the random oracle model.
      
The scheme is also provably secure against adaptively chosen ciphertext attacks in the random oracle model.
      
Furthermore, the scheme is provably secure under the assumptions that the hash function closely behaves like a random oracle and that the elliptic curve computational Diffie-Hellman problem is difficult.
      
Future, we give the security proof of our scheme under the random oracle model.
      
We prove its semantic security and unforgeability under the Gap Diffie-Hellman problem assumption in the random oracle model.
