With the rapid technological development of information technology, computer systems and especially embedded systems are becoming more mobile and ub- uitous.
Since the mid 1990s, data hiding has been proposed as an enabling technology for securing multimedia communication, and is now used in various applications including broadcast monitoring, movie fingerprinting, steganography, video indexing and retrieval, and image authentication.

Today, PKIs have come of age and they support the security of several large networked systems, such as company-wide document management systems,- governmentapplicationsandsecureVPN.
In the past few years, intelligence and security informatics (ISI) research, which is concerned with the study of the development and use of advanced information te- nologies and systems for national and international security-related applications, has experienced tremendous growth and attracted substantial interest from academic - searchers in related fields as well as practitioners from both government agencies and industry.
In recent years applied cryptography has developed considerably to satisfy the - creasing security requirements of various information technology disciplines, such as telecommunications, networking, database systems, mobile applications and others.
