It combines the advantages of the identity-based cryptography and the traditional PKI. Many certificateless public key encryption and signature schemes have been proposed. However, the key agreement in CL-PKE is seldom discussed. In this paper, we present a new certificateless two party authentication key agreement protocol and prove its security attributes. Compared with the existing protocol, our protocol is more efficient.展开更多

One of the various facets concerning the availability of class arbitration has gathered overwhelming discussion in the US. According to the decisions of the United States Supreme Court, whether class action is applicable is probably decided by the arbitrator＇s interpretation of the parties＇ intent when an adequately drafted arbitration clause is silent on this issue, regardless of the correctness of his/her construing of the contracts. The contract interpretation theory is a conclusion of existing jurisprudence while the question of arbitrability doctrine may be a hint or inkling from a recent court decision. Comparing these two sides, it is better to regard the availability of class arbitration for silent agreements as a matter of contract interpretation. Although it is preferable to regard the availability issue of class action as a contract interpretation question, some restrictions on the arbitrators＇ broad contract interpretation needs to be imposed so that the parties＇ real intent can be properly enforced.展开更多
