On the security of Joint Signature and Hybrid Encryption
Y. P. Singh M. Ayoub Khan · 2006
This paper presents the security of joint signature and hybrid encryption. The proposed scheme combines the security of a document by hybrid encryption method and authenticity by digital signatures. IDEA-RSA algorithm is used for hybrid encryption and RSA digital signature algorithm is used to obtain digital signature (D). This joint signature scheme uses "encrypt-then-sign (/spl epsi/tS)" instead of, "sign-then-encrypt (St/spl epsi/)". The security of RSA Digital Signature (D) amplifies the privacy of /spl epsi/tS. The effectiveness and correctness of the proposed scheme is illustrated through implementation and its results. The proposed scheme achieved a speed of 2.8 Mbps.
