Analyzing Digital Signature Robustness with Message Digest Algorithms
In this paper, the authors have analyzed the robustness of various message digest with respect to digital signature. The repetitive sequences in the digest will decrease the robustness of the message digest as it can lead to same message digest for differing message blocks. In this paper, the robustness of message digest is analyzed with respect to sequence repetitions as digest with more repetitive sequence are more likely or have increased probability of generating the same digest for differing message blocks. They have analyzed the robustness of various popular message digest algorithms such as MD5, SHA1, RIEMD160, PANAMA, and TIGER.
