Abstract: Recently, many cryptographic techniques have been used for secure e-voting sys-tems and e-auction systems. In this paper, we compare the used cryptographic techniques of e-voting systems with those of e-auction systems. We analyze advantages and disadvantages of various cryptographic

Abstract. In this paper, a passive UHF reader design with cryptographic technique SM2 is presented. By designing board compatibility of security module, RFID control module, RF module, communications interface, the passive UHF reader can both operate at common mode and security mode. This design

, access control, and administrative and management policy required to provide an acceptable level of protection for Hardware and Software, and information in a network. Only one particular element underlies many of the security mechanisms in use: Cryptographic techniques; hence our focus is on this area

remains to be undercover. This paper discusses about the two most promising cryptographic techniques, that are, if implemented correctly can effectively mitigate the security threats and can help in an increased uses of cloud computing.

. In our approach we prevent the clipboard data by encrypting the content at the time of copying & cutting and decrypting at the time of pasting, for this we use cryptographic techniques.

We introduce the spi calculus, an extension of the pi calculus designed for the description and analysis of cryptographic protocols. We show how to use the spi calculus, particularly for studying authentication protocols. The pi calculus (without extension) suffices for some abstract protocols

We present general definitions of security for multi-party cryptographic protocols, with focus on the task of evaluating a probabilistic function of the parties' inputs. We show that, with respect to these definitions, security is preserved under a natural composition operation

cryptographically generated image shares in the host images to provide authentication for the VC shares and makes these secret shares invisible by embedding them into host images. The secret shares generated from VC encryption are watermarked into some host images using digital watermarking. Digital watermarking

Abstract- The paper introduces a new algorithm for encryption and decryption. The process of substitution and genetic function is the core of the algorithm. With the use of the below mentioned method encryption or decryption of a message would be done in a new way. All are shown in Figure I

. Intuitively, a safe enclosure is a cryptographic primitive that encapsulates data in a way that allows to perform some computation on it, while at the same time protecting the server from malicious data. Furthermore, a safe enclosure should come equipped with a dedicated protocol that implements the enclosing
