Efficient Batch Signature Generation using Tree Structures

Abstract

E-mail: fpavlovsk, [email protected] Abstract We propose an efficient batch signature generationscheme for signing multiple messages simultaneously. The scheme can be based on any signature scheme with ap-pendix and resultant signatures preserve the property of independent verification by different recipients. The scheme isshown to be of almost constant complexity for both generation and verification as the number of messages increaseswhile the size of the signature increases only logarithmically with the number of messages in the batch. It is demon-strated that the security of the batch signature is equivalent to the security of the underlying signature mechanisms
