Abstract: The increasing number of clients and users of e-banking, e-government and e-application through digital communications, made it a must to develop new methods and solutions for authentications and secure access. Digital certificates are one of these methods for secure transactions, X.509 certificate is one standard for these digital certificates, Despite the fact that x.509 certificate is of high level of security and authenticity, it has many weaknesses as not applying dynamic delegation to it.. The efficiency of proxy certificate which proposed as a practical solution in the field of dynamic delegation could not find solutions for its weaknesses Which were the main motivation to work on this research trying to come up with new solution which integrates the pros of X.509 and the pros of Proxy certificate to benefit from the specifications of each one and to avoid the weaknesses of them. this paper will cover the standard of Digital certificates and its relation with dynamic delegation, focusing on the weaknesses of applying these standards to dynamic delegation then we propose our solution to make it applicable and more efficient to apply dynamic delegation to digital certificate standards. Finally we will cover the pros and cons of our new solution, some conclusions and future work
