Abstract: The development of technologies such as Mobile and Adhoc networks have made the distributed environments widely accepted as they allows large scale support for resource sharing infrastructure. One of the challenging issues for such environments is secure authentication. We considered the role of threshold cryptography to provide advanced security for the MANETs, revealing the authorization process using threshold digital signature, proxy signature and multi-signature in ID-based and CA-based structures. In this paper after taking a review of various proposed schemes, problems and attacks for MANETs and their solutions, In order to make any system secure, the security services such as authentication, confidentiality, integrity, availability and non repudiation must be satisfied. However, in case of distributed environment, separate and advanced security techniques have to be implemented. As mentioned earlier, one the major challenge that needs to be addressed is security of authentication. We conclude some issues and determine some challenges that can take place in future.
