The visual quality of reconstructed image is very poor by the VCS. Another one polynomial-based secured image sharing scheme can recover the distortion levels very less in the secret image, but its decoding process needs Lagrange interpolation [5], [6]. The authors combined the VCS and polynomial-based secured image sharing to design and development by a two-in-one VCS, with different types of decoding options [7], [8]. This two-in-one Visual cryptographic scheme is having two parts, first stage is stacking to see a formless reconstructed image and the second stage is used to reconstruct the secret image perfectly by Lagrange interpolation. In the symmetric key cryptography, both transmitter and receiver use a same key for encryption and decryption and it needs a secure channel or a trusted third party to exchange the key. In other words, the security of the symmetric key cryptography depends on the way of key exchange to some extent. To avoid this issue, public-key cryptography was used, in which a transmitter and a receiver own different private keys and share a public key. The keys are mathematically related. Encryption and decryption are performed by using the public key and the private key. The security of the public-key cryptography mainly lies on the complexity of the mathematical relationship between the public key and private key [9], [10]. In previous years the author of paper [11] have analyzed exam results from the Data Security course and noticed that students had trouble understanding cryptographic algorithms, which resulted in lower grades on the part of the exam covering this area and consequently the final grades for the exam. The reason for this was the difficulty for students to closely follow the execution of algorithms, because they are too complex to be calculated manually on paper. In order to help students to better understand the material many teachers in different areas use educational software systems. These systems have a significant presence in engineering sciences, where it is important for students to have practical work in addition to classes. Systems differ significantly depending on the area in which they are used. It is common in hardware related courses to use software simulators in order to avoid the high price of the necessary equipment for the laboratory exercises. In software related areas that teach algorithms, software systems for visual representation of the algorithms [12] are often used for both teaching and laboratory exercises. In [13], an algorithm is introduced to the encryption and decryption method is used to speed up the execution process. That algorithm is called up Advanced Encryption Standard (AES) cryptosystems. Even though the traditional cryptographic techniques could be applied separately to Abstract Data security is the very important part in the network data communication. Avoidance of the information hacking and steeling are very challenging part for network data communication. Now-adays people are using many encryption and decryption techniques for data security. But all encryption and decryption techniques are having more time occupation or less security for the process. This paper proposed high level security approach to encryption and decryption for data security. Two levels of securities are used in this proposed method. First one is data encryption and the second one is hash value generation. The proposed Weaving based Superior Encryption Standard (WSES) uses a novel weaving based approach. The weaving array generation is done by Elementary Number Theory Notation (ENTN) method. The weaving array has multiple private keys for XOR encryption. After encryption the error value is extracted from the encrypted array and weaving array. This error value is sent to the other side. The novel approach for hash value generation uses the encrypted array. After encryption, the encrypted array is rotated into four degrees and each degree data are converted to vector format and arranged on by one under the vector. Finally a 2D Rotational Encryption Matrix (REM) is obtained. After this process a REM copy is converted to mirror flip and it is need as Flipped Matrix (FM). The FM is concatenated under the REM and converted to vector using the zigzag operation. Finally this process gives two bytes hash value from the vector. This proposed method executes very fast and provide high security. This method is much reliable to small size applications and also used for any type of data security.

INTRODUCTION Secret sharing schemes have been independently introduced by Blakley [1] and Shamir [2]. In the Shamir’s secret sharing scheme said by, a secret m is divided into n number of pieces m1; . . . ; mn, which satisfies, 1) knowledge of whichever t or more mi pieces makes m easily computable, and 2) knowledge of whichever t-1 or fewer mi pieces leaves m completely undetermined. Shamir’s secret sharing scheme, which is also called as (t, n) secret sharing, can be proven to be informationtheoretically secure. Sahai and Waters [3] are addressed this issue by introduce the notion of Attribute Based Encryption (ABE). The ABE is a new public key based one-to-many encryptions and that encryption standard enables access control over encrypted data using access policies which are associated with private keys [4]. Visual cryptographic scheme (VCS) is a category of secret image sharing schemes. In a threshold (k, n), where k ≤ n, a secret image is encrypted into n shadow images (shadows) by 1200 ISSN: 2229-6948(ONLINE) ICTACT JOURNAL ON COMMUNICATION TECHNOLOGY, DECEMBER 2015, VOLUME: 06, ISSUE: 04 communication channels, exchange the secret keys are required to between transmitter and intended receiver. The Advanced Encryption Standard (AES) design implementation utilized 16 map online and offline key expansion. A simple design utilized only eight cores for online key expansion and six cores for offline key expansion. This implementation explores to the data level and task level parallelism. This implementation’s main aim is to reduce the core and increased the workload [14]. Patient health record system is encrypted with Attribute Based Encryption (ABE). It is mainly focus on multiple data owner’s situation. The multiple security domains reduced the key management complexity for owner and user [15]. In cloud security with the involvement of the third party cloud services, a crucial problem is that the identity attribute in the Access Cont (...truncated)
