الملخص الإنجليزي

Signcryption, which was invented by Yelling Zheng in 1997, is a recent security approach that is used to secure the communication between two or more communicated parties with low computational cost compared to sign-then-encrypt.

Signcryption is a public key cryptography, which depends on performed digital signature and public key encryption in a single logical step.

Signcryption has been implemented using various signature schemes such as ElGamal’s shortened digital signature schemes, Proxy signature scheme, RSA digital signature, elliptic curve digital signature and Schnorr’s signature scheme.

Researchers are still working to find out the most effective method for signcryption.

In this thesis, a new efficient signcryption approach based on Rabin cryptosystem is proposed.

Rabin public cryptography is one of the earlier mechanisms, which is characterized with a smaller computational cost that depends on factorization.

Rabin has the property of being difficult to find the private keys.

This work represents a new signcryption approach based on Rabin digital signature, and the proposed approach is verified against the security concerns in addition to measuring the running time.

Rabin Cryptosystem has a problem of decryption as it gives four results instead of one, which means that only one of them represents the original message.

Chinese Reminder Theorem (CRT) is used to get the solution in Rabin cryptosystem decryption.

This process is critical in the proposed Rabin signcryption.

In this thesis, the Proposed Signcryption based on Rabin cryptosystem is implemented and the execution time for signcryption and unsigncryption is measured.

Then, there is a comparison between the Proposed Signcryption and the original signcryption in terms of effectiveness.

The Proposed Signcryption satisfied the security concerns: confidentially, unforgeability, integrity, non-repudiation and forward secrecy.

The security concerns have been proven based on the factorization problem.

Compared to the original signcryption (SDSS1 & SDSS2) the Proposed Signcryption is achieve more effectiveness for signcryption process in the sender side at a rate of 24.1%.

But in the unsigncryption process the Proposed Signcryption is achieve less effectiveness at a rate of 18.3%.

In full execution time the Proposed Signcryption is achieve more effectiveness at a rate of 3%.

By taking advantage of the signcryption speed on sender side the Proposed Signcryption is suitable for Smart Cards and Wireless Sensor Network (WSN).
