Nowadays, digital communication protocols rely on cryptographic mechanisms to protect sensitive information from unauthorized access and modification. Cryptographic primitives, such as hash functions, block and stream ciphers, are key components of many information security applications, employed to provide privacy, authentication, and data integrity. Following the massive differentiation of modern communication technologies, cryptography must be able to provide highly-efficient algorithms that combine strong security with optimal implementability.
This work focuses on the design of VLSI circuits for cryptographic hash functions and block cipher authenticated encryption modes. Two hash algorithms, submitted to the NIST hash competition, and a new hash function family for resource-limited applications, such as embedded systems and portable devices, are presented. In addition, implementation results for efficient highspeed architectures of the Advanced Encryption Standard in the Galois/Counter Mode of operation are described.
