A Hybrid and Efficient Scheme of Multicast Source Authentication
Jin-xin He, Gaochao Xu, Xiaodong Fu, Zhiguo Zhou · 2007
Source authentication is the most important and difficult problem in multicast security, and no schemes can satisfy all multicast applications. So a hybrid multicast source authentication (HMSA) scheme was proposed based on two data structures: hashing tree and hashing chain. Compared with some other schemes in computation and communication overheads, HMSA is simple, efficient and secure.
