The invention discloses a motor controller convenient for heat dissipation. The motor controller comprises a motor controller body, an operation threaded rod, a first bottom plate, a second bottom plate and a working bolt, wherein the operation threaded rod is installed on the side of the motor controller body, a stabilizing plate is attached to a track groove, the track groove is formed in the side of the motor controller body, the bottom of a lower heat dissipation positioning block is provided with supporting rods, the bottom ends of the supporting rods are respectively connected with the first bottom plate and the second bottom plate, a horizontal inserting plate is fixed to the side of the first bottom plate, the horizontal inserting plate is connected with the second bottom plate, and the second bottom plate is provided with a working bolt. According to the motor controller convenient for heat dissipation, a novel structural design is adopted, the device can effectively dissipateheat at a metal interface, carry out isolation and positioning on an external wire harness, and adjust the overall height of the motor controller, so that all surfaces of the motor controller can bein full contact with air, and the heat dissipation efficiency is improved.

Secret-key negotiations are important that enable any user to achieve information security as well as data privacy. Two efficient key negotiation schemes, which provide base security for developing different cryptographic techniques, are proposed. We work with Shamir’s (t, n) threshold secret sharing scheme (SSS) and provide protection against misbehaved activities of dealer and/or dishonest participants as they exist in the scheme unfortunately. The first SSS is designed based on subset secret such that if the reconstructed secret belongs to this set, then probably, no share cheating is occurred. The other scheme has two variations―(1) a dealer-based (t, t) SS and (2) a KGC-based (t, n) SS, where shares’ cheating and both dealer and shares’ cheating are protected as key generation center (KGC) is cryptographically trusted and used in variety of security applications. As performance study, a comparison of the proposed SSSs with Shamir’s one is given.

Asymmetric group key agreement allows a group of users to negotiate a common public encryption key, and each user only holds his own secret encryption key. Authenticated asymmetric group key agreement (AAGKA) protocol is a kind of AGKA protocols which can be secure against active attacks. Dynamic asymmetric group key agreement allows any member to join and leave at any point. This paper studies dynamic AAGKA in certificateless cryptography. We first pointed that Wei et al.’s dynamic certificateless AAGKA protocol suffers from a key compromise impersonation attack, and cannot provide secrecy or forward secrecy. We then proposed an improved dynamic certificateless AAGKA protocol. Security proofs show that our protocol can provide security attributes including secrecy, known-key security, key compromise impersonation resistance, forward security, non-repudiation, and privacy. Furthermore, the proposed protocol is still efficient.
