New Hybrid Signcryption Approach: Efficient Digital Envelope Signcryption
Aye, The` Seint
Soe, Than Naing
In the study of Cryptography, the most important andwidely studied are confidentiality and integrity.Confidentiality is supported by encryption schemes,while integrity is provided by digital signature schemes.Drawback of symmetric encryption is key distributionproblem. Although asymmetric encryption can solve thisproblem, all of these ciphers are hundreds or thousandsof times slower than symmetric ciphers. Digitalenvelope combines the advantages of asymmetric andsymmetric key ciphers. It eliminates time complexityproblem of asymmetric encryption and key exchangeproblem of symmetric encryption. But it cannot providedata integrity. So it cannot be avoidable to use digitalsignature scheme to guarantee the source and integrity.New hybrid signcryption approach named “EfficientDigital Envelope Signcryption” is proposed. This newapproach operates digital signature process andasymmetric encryption process in a single step. It takesadvantages of digital envelope scheme and signcryptionscheme with appropriate algorithms.
