Improved Digital Signature Solution
Lijuan Li · Science Technology and Engineering · 2008
Based on the analysis of the shortage of existing digital signature solution,an improved digital signature solution was proposed according to the advantage of symmetrical key algorithm,asymmetrical key algorithm and unidirectional hashing function. It successfully solved the problem of symmetrical digital signature caused by the difficulty to store key and indispensability of arbitrator. And it also avoided the disadvantage of asymmetrical digital signature that it was too slow to suit for the long file signature.
