چکیده

Helix is a high-speed stream cipher with a built-in MAC functionality. On a Pentium II CPU it is about twice as fast as Rijndael or Twofish, and comparable in speed to RC4. The overhead per encrypted/authenticated message is low, making it suitable for small messages. It is efficient in both hardware and software, and with some pre-computation can effectively switch keys on a per-message basis without additional overhead.

Phelix Fast Encryption and Authentication in a Single Cryptographic Primitive

Phelix is a high-speed stream cipher with a built-in MAC functionality. It is efficient in both hardware and software. On current Pentium CPUs, Phelix has a per-packet overhead of less than 900 clocks, plus a perbyte cost well under 8 clocks per byte, comparing very favorably with the best AES (encryption-only) implementations, even for small packets.

ID based generalized signcryption

Generalized signcryption is a new cryptographic primitive in which a signcryption scheme can work as an encryption scheme as well as a signature scheme. This paper presents an identity based generalized signcryption scheme based on bilinear pairing and discusses its security for message confidentiality non repudiation and ciphertext authentication.

An Efficient Scheme for Sensitive Message Transmission using Blind Signcryption

Y. Zheng introduced a new cryptographic primitive Signcryption in [12], which combines digital signature function with a symmetric key encryption algorithm. A digital signature is used for authentication of message and an encryption scheme is used for the confidentiality of messages. A signcryption offers these two properties at the same time and more efficiently. Computational cost in Signcryp...

Block encryption of quantum messages

In modern cryptography, block encryption is a fundamental cryptographic primitive. However, it is impossible for block encryption to achieve the same security as one-time pad. Quantum mechanics has changed the modern cryptography, and lots of researches have shown that quantum cryptography can outperform the limitation of traditional cryptography. This article focuses on block encryption of qua...

LOKI - A Cryptographic Primitive for Authentication and Secrecy Applications

This paper provides an overview of the LOKI encryption primitive which may be used to encrypt and decrypt a 64-bit block of data using a 64-bit key. It has been developed as a result of work analysing the existing DEA-1, with the aim of designing a new family of encryption primitives [Brow88], [BrSe89], [BrSe90], [PiFi88], [Piep89b], [Piep89a], [PiSe89]. Its overall structure has a broad resemb...
