Security of Block Ciphers: From Algorithm Design to Hardware Implementation [Hardcover]

• Written by authors known within the academic cryptography community, this book presents the latest developments in current research
• Unique in its combination of both algorithmic-level design and hardware-level implementation; this all-round approach - algorithm to implementation  covers security from start to completion
• Deals with AES (Advanced Encryption standard), one of the most used symmetric-key ciphers, which helps the reader to learn the fundamental theory of cryptanalysis and practical applications of side-channel analysis
