Parallel stream cipher for secure high-speed communications
نویسندگان
چکیده
Due to ongoing improvements in high-speed communications, the speed of data encryption must also increase. Accordingly, this paper proposes an PS-LFSR with an m(¿ 2)-times faster shifting during one clock interval and a parallel stream cipher that is faster by paralleling many similar keystream generators using the PS-LFSRs. Finally, an m-parallel SUM-BSG with 8-parallel for detail is proposed as a design example of the proposed parallel stream cipher. When compared with a conventional stream cipher, the properties of the proposed cipher exhibited the same crypto-degree with m-times faster processing. ? 2002 Elsevier Science B.V.

All-Optical Cryptographic Device for Secure Communication
An all-optical cryptographic device for secure communication, based on the properties of soliton beams, is presented. It can encode a given bit stream of optical pulses, changing their phase and their amplitude as a function of an encryption serial key that merge with the data stream, generating a ciphered stream. The greatest advantage of the device is real-time encrypting – data can be transm...
متن کاملA Study on the Stream Cipher Embedded Magic Square of Random Access Files
Magic square and stream cipher issue are very interest well-tried topic. In this paper, we are proposed a new scheme which stream cipher application for random access file that based on magic square method. By the way, there are two thresholds to secure ours data, if decrypts only by the stream cipher. It isn’t to recovery original source. In other hand, we improve the model of cipher stream to...
متن کاملA Practical Approach to the Design of High Speed Self-Synchronizing Stream Ciphers
??1? An engineering oriented approach for the design of selfsynchronizing stream ciphers is given. To show that it is useful in practice, an actual design is presented and motivated. This SSSC is claimed to be fast (gate delay 2 XORs), cryptographically secure and easily implementable in hardware (standard cells).
متن کاملAn Efficient Stream Cipher Algorithm for Data Encryption
Nowadays the data telecommunication security has been provided by most of well-known stream cipher algorithms which are already implemented in different secure protocols such as GSM, SSL, TLS, WEP, Bluetooth etc. These algorithms are A5/1, A5/2, E0 and RC4. On the other hand, these public algorithms already faced to serious security weakness such that they do not provide enough security of prop...
متن کاملExtending the Salsa20 nonce
This paper introduces the XSalsa20 stream cipher. XSalsa20 is based upon the Salsa20 stream cipher but has a much longer nonce: 192 bits instead of 64 bits. XSalsa20 has exactly the same streaming speed as Salsa20, and its extra nonce-setup cost is slightly smaller than the cost of generating one block of Salsa20 output. This paper proves that XSalsa20 is secure if Salsa20 is secure: any succes...
