Methods for optimization of digital signatures
 Špidla, Aleš ; Hajný, Jan (referee) ; Malina, Lukáš (advisor)
The thesis briefly describes the digital signatures and basic methods (RSA, DSA, ECDSA) for the creation and verification of the digital signature. The method of group signatures designed by Boneh, Boyen and Shacham (BBS) is described in more details as well as the method designed by Bonen and Shacham (BS). The thesis further explores related issue of the implementation of batch signing and verification for the above mentioned methods and their practical application, particularly for systems Vehicular ad-hod network (VANET) and cloud storage in the field of forensic IT. The purpose of the thesis is to determine which of the methods BBS and BS is more suitable for these systems in terms of computational complexity. For this reason, the author created the program for the comparison of methods BBS and BS. The programme compares the time consumption of the methods for signing and verification of incoming messages. The results of the measurement are summarized in the conclusion along with the justification why the particular methods are suitable for the systems.
