1. Introduction
Symmetric key cryptosystems are an important type of modern cryptosystem [1, 2, 4, 5, 8, 11, 13]. Symmetric key systems are cryptosystems where the same key is used for both encryption and decryption. This class of cryptosystem is important in modern cryptography because, in general, symmetric key cryptosystems are much faster than public key cryptosystems. Stream ciphers, on the other hand, process plaintext in small blocks (sometimes as small as a single bit). In contrast to block ciphers, stream ciphers keep some sort of memory, or state, as it processes the plaintext and uses this state as an input to the cipher algorithm [14-15]. In this paper, we are proposed a new scheme stream cipher contain magic matrix [3, 6, 7, 9, 10], to strong a random access file that you already to protect it. Section 2 will describe what kind of cipher schema did we concept in practice. Section 3 is discussing magic square that it will apply in random access file while encryption already implements early. Part 4, it is analysis the reliability with decrypt and encrypt; Conclusion and future research will be mention in final section.
