To tackle the key-exposure problem in signature settings,this paper introduces a new cryptographic primitive named threshold key-insulated signature(TKIS) and proposes a concrete TKIS *** a TKIS system,at least k out of n helpers are needed to update a user's temporary private *** the one hand,even if up to k 1 helpers are compromised in addition to the exposure of any of temporary private keys,security of the non-exposed periods is still *** the other hand,even if all the n helpers are compromised,we can still ensure the security of all periods as long as none of temporary private keys is *** with traditional key-insulated signature(KIS) schemes,the proposed TKIS scheme not only greatly enhances the security of the system,but also provides flexibility and efficiency.

To analyze the fatigue life of a fifth wheel saddle body, we established the three dimensional model of the saddle body by CATIA software, and imported it into ANSYS software, and modified to the FEM model, and meshing it. By researching relevant information we rendered the material simplified S-N curve. Considering a variety of factors of influencing the fatigue strength, we amended the material S-N curve. Finally, we analyzed the fatigue life of the saddle body and found the saddle body positions that easily take place fatigue damage. The positions are at the connection region of the second beam and transfer force parts. The region should be sufficient attention in the development process.
