in this project have been done in descriptive-analyze method, mid utilize from mythology-psychology by studying women characters in five plays. we are searching traits of “wild woman archetype” in secret defense drama. this archetype has been formed from theories of carel gustave yung, unregarded in literary and artistically studying in my country. important asking in this article is introducin...

Visual cryptography is a secret sharing scheme where a secret image gets divided into number of pieces called shares and not a single share disclose any information about secret image. There are some automated methods to identify and verify the user based on the physiological characteristics. To deal with such methods, there is a technology called biometrics which measures and statistically ana...

In this paper, firstly, we introduce a new security definition called secret key awareness security which is to guarantee anyone generating the public key to know the corresponding secret key. Following, we give a concrete implementing for secret key awareness security. Secondly, we present two applications: one is in plaintext awareness security cryptosystem, and another is in certificatless p...

A perfect secret-sharing scheme is a method to distribute a secret among a set of participants in such a way that only qualified subsets of participants can recover the secret and the joint share of participants in any unqualified subset is statistically independent of the secret. The collection of all qualified subsets is called the access structure of the perfect secret-sharing scheme. In a g...

In this paper, a method is proposed to construct a visual secret sharing (VSS) scheme for multiple secret images in which each share can be rotated with 180 degrees in decryption. The proposed VSS scheme can encrypt more number of secret images compared with the normal VSS schemes. Furthermore, the proposed technique can be applied to the VSS scheme that allows to turn over some shares in decry...

In the previous lecture, we discussed the concept of Secret-Key Encryption. However, this scheme has a major limitation in the fact that the key has to be shared between the sender and the receiver before any message can be transmitted. There might be several cases where doing this is infeasible if there has been no prior communication between the sender and the receiver. In today’s lecture, we...

Secret sharing is a new alternative for outsourcing data in a secure way. It avoids the need for time consuming encryption decryption process and also the complexity involved in key management. The data must also be protected from untrusted cloud service providers. Secret sharing based solution provides secure information dispersal by making shares of the original data and distributes them amon...

Building upon the recent work in communication efficient classical secret sharing schemes of Bitar and El Rouayheb, we study communication efficient quantum secret sharing schemes. In the standard model of quantum secret sharing, typically one is interested in minimal authorized sets for the reconstruction of the secret. In such a setting, reconstruction requires the communication of all the sh...
