摘要：Communication and information exchange is the activity that apart from daily life. Instant messaging is one of the communication media by using internet protocol. In Many cases of tapping data and hacking information is a problem. Using a cryptography algorithm could secure the data information or message. Using a single algorithm of cryptography is still weak to send the data or information through the internet. Using a Hybrid cryptosystem scheme can solve this problem with the excellent implementation in instant messaging, that message will secure by RC4+ algorithm; this type is a symmetric algorithm that using one key, fast in the process but not secure enough, and the key of RC4+ algorithm will secure by Multi-factor RSA algorithm this type is Asymmetric algorithm has two key, but the process is slower than RC4+ but strong. The results showed that the hybrid combination of 2 algorithms cryptography successfully secures the message and is the key to ensuring that message, proving this scheme could secure faster than another combination of RC4+ and Multi-factor RSA.
