Cryptography is the practice and study of Encrypting/Decrypting information. In modern times cryptography is considered a branch of both mathematics and computer science and is affiliated closely with information theory, computer security and engineering. Cryptography is used in applications present in technologically advanced societies; examples include the security of ATM cards, computer passwords and electronic commerce, which all depend on cryptography. The algorithms and methods used to encrypt messages in Arabic language are few and old; there are no modern encryption algorithms to encrypt the Arabic letters. This research paper proposed the mixed encryption algorithm based on simple multiplication and logarithm function with Caesar cipher to solve the problem. Our method is easy to adopt the coding of advanced language and is safe enough. The security mechanism uses some algorithms to scramble data into unreadable text which can be only being decoded or decrypted by party those know the secret key. The proposed algorithms consume very less amount of computing resources such as CPU time, memory, battery power and cost effective.
