Developers tasked with security problems are often not cryptographers themselves. They are bright people who, with careful guidance, can implement secure cryptosystems. This book will guide developers in their journey towards solving cryptographic problems. If you have ever asked yourself just how do I setup AES? then this text is for you.
*ASN.1 Encoding The chapter on ASN.1 encoding delivers a treatment of the Abstract Syntax Notation One (ASN.1) encoding rules for data elements such as strings, binary strings, integers, dates and times, and sets and sequences.
*Random Number Generation This chapter discusses the design and construction of standard random number generators (RNGs) such as those specified by NIST.
*Advanced Encryption Standard This chapter discusses the AES block cipher design, implementation trade-offs, side channel hazards, and modes of use. It concentrates on the key design elements important to implementers and how to exploit them in various trade-off conditions.
*Hash Functions This chapter discusses collision resistance, provides examples of exploits, and concludes with known incorrect usage patterns.
*Message Authentication Code Algorithms This chapter discusses the HMAC and CMAC Message
*Authentication Code (MAC) algorithms, which are constructed from hash and cipher functions.
*Encrypt and Authenticate Modes This chapter discusses the IEEE and NIST encrypt and authenticate modes GCM and CCM. Both modes introduce new concepts to cryptographic functions. Focus is given to the concept of replay attacks, and initialization techniques are explored in depth.
*Large Integer Arithmetic This chapter discusses the techniques behind manipulating large integers such as those used in public key algorithms.
*Public Key Algorithms This chapter introduces public key cryptography, including the RSA algorithm and its related PKCS #1 padding schemes. It also introduces new math in the form of various elliptic curve point multipliers. |

The digital age is upon us. No longer is instant access to information a request – it is now a requirement.
Serving as a backbone for instant access is the relational database management system. Databases serve
as the warehouses of digital information and hold our most critical assets. As such, to properly maintain
the integrity and confidentiality of this data, the need for securing databases is growing. One of the
requirements for securing databases is to encrypt the information stored within them.
Unfortunately, there are many misconceptions surrounding what database encryption is and how it should
be performed. Encryption is a complex subject and properly implementing it requires a grasp of not only
the theories behind encryption, but also the practical applications in the real world. All too often, the line
between access control and encryption is blurred, and encryption solutions simply supplement the access
controls already in place. What we hope to outline in this paper is an appropriate use of encryption as
well as its proper implementation. |

The relational data model was first developed in 1970 by Dr. E. F. Codd. This relational model is the foundation for relational
database management systems which are the current de facto standard for storing corporate information. In 1985, Dr. Codd
published the 12 rules that provide the guideline for these relational systems. Unfortunately, at the time there was little concern
for the security of the data in these systems. In the early days, gaining access to a database was so difficult that the need for
security features such as encryption on the data was irrelevant. Because of the environment, there is little built into these rules
to allow for the encryption of the data. |
