TL;DR: A new on-line payment scheme for mobile network that provides consumer anonymity, authentication, non-repudiation and data integrity properties, which takes lower computation cost and is more suitable for mobile device.

TL;DR: The proposed scheme generates multiple shared keys for two parties at a time and does not only withstand general attacks, also provides perfect forward secrecy by making comparisons with other method, it takes less computation time.

TL;DR: The proposed protocol is based on weil pairing, ID-based authentication and a complete binary tree architecture and is efficient when the group member is small and dynamically changing.

TL;DR: An efficient and practical authenticated key agreement protocol based on the line of geometry that provides mutual authentication between the user and the server and enables them to establish a common session key to provide message confidentiality for each other is proposed.

TL;DR: The proposed scheme allows user to access multi-server securely by keeping one weak password and a smart card only and does not use the overload cryptography operations, it is more efficient than the previous results.
