Transcendental logarithm problem is a new problem which can be used to build signature schemes. Although no polynomial time algorithm or sub-exponential time algorithm has been found to solve this problem, whether it is still an intractable problem with quantum computers is a question. In this paper, we solve the transcendental logarithm problem with improved Grover's quantum search algorithm. In...
The emerging trend of outsourcing database to third parties motivates the research of protecting sensitive data from database service providers. The bucket-based method is one of the feasible methods to store those data encrypted. Since a bucket may contain many different attribute values, this method also introduces some false query results when performing queries over encrypted databases. Strategies...
