Handycipher: a Low-tech, Randomized, Symmetric-key Cryptosystem
نویسنده
چکیده
Handycipher is a low-tech, randomized, symmetric-key, stream cipher, simple enough to permit penand-paper encrypting and decrypting of messages, while providing a significantly high level of security. It combines a simple 31-character substitution cipher with a 3,045-token nondeterministic homophonic substitution cipher, and employs the insertion of randomly chosen decoy characters at random locations in the ciphertext.

Improving the Rao-Nam secret key cryptosystem using regular EDF-QC-LDPC codes
This paper proposes an efficient joint secret key encryption-channel coding cryptosystem, based on regular Extended Difference Family Quasi-Cyclic Low-Density Parity-Check codes. The key length of the proposed cryptosystem decreases up to 85 percent using a new efficient compression algorithm. Cryptanalytic methods show that the improved cryptosystem has a significant security advantage over Ra...

This paper introduces a new concept of textual message encryption and decryption through a pool of randomized symmetric key and the dual layer cryptosystem with the concept of visual cryptography and steganography. A textual message is converted into two image slides, and the images are encrypted through two different randomized sequences of symmetric key. The decryption is done in the reverse ...
متن کاملHardware Implementation of Dynamic S-BOX to Use in AES Cryptosystem
One of the major cipher symmetric algorithms is AES. Its main feature is to use S-BOX step, which is the only non-linear part of this standard possessing fixed structure. During the previous studies, it was shown that AES standard security was increased by changing the design concepts of S-BOX and production of dynamic S-BOX. In this paper, a change of AES standard security is studied by produc...

The present paper proposes a new cryptographic algorithm called Ultra Encryption Algorithm (UEA). Nath et al recently developed few efficient encryption methods such as UES version-I, Modified UES-I, UES version-II, TTJSA, DJMNA Nath et. al showed that TTJSA and DJMNA is most suitable methods to encrypt password or any small message. The name of the present method is Ultra Encryption Algorithm ...
متن کاملHybrid encryption/decryption technique using new public key and symmetric key algorithm
This research study proposes Hybrid Encryption System using new public key algorithm and private key algorithm. A hybrid cryptosystem is one which combines the convenience of a public-key cryptosystem with the efficiency of a symmetrickey cryptosystem. Here, we propose a provably two way secured data encryption system, which addresses the concerns of user’s privacy, authentication and accuracy....
