Launched by ECRYPT in 2004, the eSTREAM project sought to advance the field of efficient and secure stream ciphers. The finalist ciphers were divided into two categories: Profile 1, optimized for high-performance software applications, features Rabbit, HC-256/HC-128, Salsa/ChaCha, and SOSEMANUK, whereas Profile 2, tailored for hardware-constrained environments, includes Grain v1, MICKEY 2.0, and Trivium. This chapter delves into the characteristics of these ciphers, with a particular focus on HC-128. Key aspects such as security, performance, simplicity, and clarity are evaluated, along with an in-depth analysis of HC-128’s structure, initialization, and keystream generation.

摘要

Launched by ECRYPT in 2004, the eSTREAM project sought to advance the field of efficient and secure stream ciphers. The finalist ciphers were divided into two categories: Profile 1, optimized for high-performance software applications, features Rabbit, HC-256/HC-128, Salsa/ChaCha, and SOSEMANUK, whereas Profile 2, tailored for hardware-constrained environments, includes Grain v1, MICKEY 2.0, and Trivium. This chapter delves into the characteristics of these ciphers, with a particular focus on HC-128. Key aspects such as security, performance, simplicity, and clarity are evaluated, along with an in-depth analysis of HC-128’s structure, initialization, and keystream generation.
