Abstract :
This paper attempts to develop a stronger and safer cryptographic algorithm which would not only be secure, but also reduces total time taken in providing integrity of information. Hash functions were introduced in cryptology as a tool to protect the integrity of information. SHA-1 and MD-5 are among the most commonly used hash function message digest algorithms. Scientists have found collision attacks on SHA-1, MD-5 hash functions so the natural response to overcome this threat was assessing the weak points of these protocols that actually depend on collision resistance for their security. So to increase the security, modified SHA-192 is introduced in this paper having a message digest of length 192 bits with larger bit difference. To generate larger bit difference, best properties of MD-5 and SHA-1 are combined. So the new solution will be no longer vulnerable to the collision attacks.
