For the obvious characteristics of time-varying nonlinear controlled object, in order to improve the control performance, the appropriate adaptive control strategy could be used. Based on the research object system of a certain amount of input to control variables, according to Lyapunov stability theory, the research object system input/output variable a model reference adaptive control system was...
A distributed admission and revocation control scheme for distributed network is proposed in this paper. The scheme uses the admission control and revocation control mechanisms to provide security services for distributed networks. The admission control is to prevent unauthorized members from joining a distributed network. The revocation control is to revoke malicious members from network once detected...
The threshold proxy signature scheme with strong real-time efficiency is proposed based on a trapdoor hash function and the sharing secret technology. In the scheme, the procedure of generating threshold proxy signature is performed in two phases. The off-line phase generates a threshold proxy pre-signature before the message to be signed is even known. The pre-signature is independent of the particular...
