This chapter takes a critical review of the digital signature schemes which are based on two hard problems. The analytical study begins with the Harn (1994) scheme and He-Kiesler (1994) scheme. Shao's 1998 and 2002 schemes have been studied. Wei-Hua He (2001) and Shimin Wei (2004, 2007) schemes are analyzed further in the research work. Attacks on Shimin Wei's (2004, 2007) schemes are critically studied and drawbacks have been noted so as to design better schemes than these. Then we continue our analysis work by studying Ismail, Thate, and Ahmad's (2008) scheme and Swati Verma's (2012) signature scheme.
