Since cryptography without a public key certificate (CLPKC) has attracted wide attention due to its effectiveness in preventing key Escrow issues in identity-based public key cryptography (ID-PKC), the CERTIFICATELESS Authenticated Key Agreement (CLAKA) protocol, an important part of CLPKC, has been the subject of much research. Most CLAKA protocols are based on couplings that require expensive operations. To improve performance, several CLAKA protocols without coupling have been proposed. In this article, we propose a new claka protocol without mating. Compared to the corresponding protocols, our protocol has a better performance. In addition, it is proven that our protocol is safe in a very powerful security model — the advanced Canetti Krawczyk (eCK) model. Lee, E. J., Lee, S.

Wireless group communication has recently gained popularity due to the rise of portable and lightweight devices. These devices are capable of performing group communications by allowing each participant to agree on a group key for secure communication over an unsecured network. Many authenticated group key agreement schemes have been proposed, but most schemes do not have the dynamic property of group membership/exit by mobile nodes, so the meeting key is updated without affecting the minutes. In this article, we propose an authenticated group key agreement protocol without a certificate without a certificate, based on a cryptosystem with elliptic curves for resource-limited mobile nodes….
