Another forward secure multi-signature scheme
Xiuyuan Yu · Journal of Hangzhou Teachers College · 2005
Another forward secure multi-signature scheme is proposed combing the concept of forward security with multi-signature. This means that an adversary cannot forge multi-signature pertaining to the past even if be gets all the current singers keys, that is, previously generated multi-signature remains valid. The forward security of the scheme relies on the strong-RSA assumption and the multi-signature relies on RSA and Hash function. Furthermore, the scheme imports time-symbol, so it can counteract multi-broadcasting.
