Abstract :
In this paper, a class of sequential multi-proxy signature schemes are attacked. It includes existential forgery attack. The scheme has many shortcomings. A new enhanced and can resist forgery attack sequential multi signature scheme is proposed, which based on the improved of the original scheme. The new scheme improved the parameters of the original scheme, improved parameter improve the shortcomings of the scheme, which set reasonable, it is correct.
