In Hill cipher encryption, the complexity of finding the inverse of the matrix during decryption is eliminated by adopting self invertible matrices. Authentication of hall tickets for candidates during examination is a complicated issue. By evaluating simultaneously encryption and decryption with details of text, photos and signatures of candidates it is easy to prevent malpractices during exam...

The MEM mode is a nonce-based enciphering mode of operation proposed by Chakraborty and Sarkar, which was claimed to be secure against symmetric nonce respecting adversaries. We show that this is not correct by using two very simple attcks. One attack need one decryption and one decryption queries, and the other only need one encryption query.

We have proposed a novel way of symmetric encryption utilizing interleaving salting, Binary Tree traversal, and an Artificial Neural Network in sequential manner. presented the use as invertible(reversible) mathematical function so that decryption encrypted output may be possible. Knowledge pipeline, salt, neural network weights is required for decryption. As same set values decryption, our app...

Security is constantly been infringed by inadvertent loss of secret keys, and as a solution, Dodis, Katz, Xu, and Yung [11], in Eurocrypt 2002, proposed a new paradigm called key-insulated security which provides tolerance against key exposures. Their scheme introduces a “helper key” which is used to periodically update the decryption key. The most attractive part of this scheme is that even if...

Trusted Cryptography Supporting Platform is a computer platform with high dependable and available software and hardware, within which security mechanism is reliable and robust because some encryption/decryption, authentication techniques are adopted upon the operating system based on the trusted platform module in a chip or ARM board. USB disk is a popular, flexible, removable storage device b...

Attribute-based encryption (ABE) with outsourced decryption not only enables finegrained sharing of encrypted data, but also overcomes the effective drawback of the standard ABE schemes. An Attribute based encryption scheme with outsourced decryption allows a third party (e.g., a cloud server) to renovate an ABE cipher text into a (short) El Gamal-type cipher text using a public transformation ...

We propose and analyze a multivariate encryption scheme that uses odd characteristic and an embedding in its construction. This system has a very simple core map F (X) = X2, allowing for efficient decryption. We also discuss ways to make this decryption faster with specific parameter choices. We give heuristic arguments along with experimental data to show that this scheme resists all known att...

The performance of a single-chip shared-memory multiprocessor system for encryption/decryption of large quantities of information is examined. The multiprocessor uses an asynchronous bus system to increase scalability and to reduce design effort. The target application is the Advanced Encryption Standard (AES) with 128 bit key. Chip area requirements and encryption/decryption throughput rates a...
