Introduction
Acetohydroxy Synthase (AHAS) (EC 4.1.3.18), also called acetolactate synthase , is the key enzyme in the biosynthsis of L-valine (Figure 1) and therefore is a potential target for metabolic engineering[1].

Introduction
With the increasing application of the sensitive data storage and sharing in distributed systems such as online social networks or public cloud storage, there have been increasing requirement and attention to distributed data security in the Internet [1].
In this phase, attribute-based encryption and signature can simultaneously be realized by the sender in the following steps: 1) The sender computes and respectively; 2) The sender computes , where is the current time; 3) The sender computes , and respectively.
Theorem 1: The receiver can correctly decrypt the ciphertext if and hold.

Introduction
Developed from the study on the behaviors of alloys in the semisolid state pioneered by Spencer et al. [1], it has been well recognized that semisolid processing (SSP) exhibits significant advantages over the traditional material processing techniques, such as good net shape capability, low energy cost, less entrapped air, fine grain size, porosity and segregation [2, 3].
Experimental procedure The main features of MRB process is illustrated schematically in Fig. 1.
