This thesis contains a new approach to design block ciphers, synchronous and self-
synchronizing stream ciphers and cryptographic hash functions. The goal of this approach is …

In this chapter, we propose a new stream cipher construction based on block cipher design
principles. The main idea is to replace the building blocks used in block ciphers by …

Self-synchronizing stream ciphers (SSSC) are a commonly used encryption technique for
channels with low bit error rate but for which bit synchronization can present a problem. Most …

Stream cipher is an important branch of symmetric cryptosystems, which takes obvious
advantages in speed and scale of hardware implementation. It is suitable for using in the …

It is now a decade since the appearance of W. Diffie and ME Hellmann's startling paper,"
New Directions in Cryptography". This paper not only established the new field of public-key …

The ultimate guide to cryptography, updated from an author team of the world's top
cryptography experts. Cryptography is vital to keeping information safe, in an era when the …

In this paper we present a family of stream ciphers which generate a keystream with ideal
two-level autocorrelation. The design also guarantees other randomness properties, ie …

The family of stream ciphers MICKEY (which stands for Mutual Irregular Clocking KEYstream
generator) is aimed at resource-constrained hardware platforms. It is intended to have low …

In some applications for synchronous stream ciphers, the risk of loss of synchronization
cannot be eliminated completely. In these cases frequent synchronization or …
