A protocol for assuring the authenticity of information broadcasted over long periods of time is proposed. The protocol is based on time synchronization and uses one-way chains con...
Most of existing user authentication schemes require high computation cost of exponentiation operations for the purpose of security. However, it is not suitable for mobile devices...
This paper gives a survey of attacks on Message Authentication Codes (MACs). First it defines the required security properties. Next it describes generic forgery and key recovery...
The security issue has become an important concern of grid computing. To prevent the grid resources from being illegally visited, the strong mutual authentication is needed for us...
We consider the problem of constructing a general protocol for secure two-party computation in a way that preserves security under concurrent composition. In our treatment, we foc...
