Master locksmith Steven Hampton, author of the best-selling Secrets of Lock Picking, takes the art of picking locks one step further with Modern High-Security Locks. Here, he collects some of today's most popular pick-resistant locks and sets out to see which ones hold up to their claims. However complex a lock gets, it must be durable, dependable and user-friendly. It has to be tough enough to endure physical attack, but it can't be machined too tight or it will jam up with just a breath of dust. It must be simple and easy to lock and unlock with its key, or the customer will not pay the higher price for it. It is this delicate balance between security and utility that allows the locksmith to open this new generation of locks. Hampton shows locksmiths how each lock is picked and how long it will take. He details the tools of the trade and includes patterns and instructions for making your own picks and tension wrenches. He even includes ancient Tibetan Buddhist tantric visualization exercises to help locksmiths learn to "see" the inner workings of the lock within the mind's eye. Veteran locksmiths or those new to the trade will find Hampton's latest book an invaluable sourcebook. For academic study only.

Cognitive networks can dynamically adapt their operational parameters in response to user needs or changing environmental conditions. They can learn from these adaptations and exploit knowledge to make future decisions. Cognitive networks are the future, and they are needed simply because they enable users to focus on things other than configuring and managing networks. Without cognitive networks, the pervasive computing vision calls for every consumer to be a network technician. The applications of cognitive networks enable the vision of pervasive computing, seamless mobility, ad-hoc networks, and dynamic spectrum allocation, among others. In detail, the authors describe the main features of cognitive networks clearly indicating that cognitive network design can be applied to any type of network, being fixed or wireless. They explain why cognitive networks promise better protection against security attacks and network intruders and how such networks will benefit the service operator as well as the consumer.

Книга предназначена для пользователей средней и высокой квалификации.

In the 1960s, it became increasingly clear that more and more information was going to be stored on computers, not on pieces of paper. With these changes in technology and the ways it was used came a need to protect both the systems and the information. For the next ten years, encryption systems of varying strengths were developed, but none proved to be rigorous enough. In 1973, the NBS put out an open call for a new, stronger encryption system that would become the new federal standard. Several years later, IBM responded with a system called Lucifer that came to simply be known as DES (data encryption standard).The strength of an encryption system is best measured by the attacks it is able to withstand, and because DES was the federal standard, many tried to test its limits. (It should also be noted that a number of cryptographers and computer scientists told the NSA that DES was not nearly strong enough and would be easily hacked.) Rogue hackers, usually out to steal as much information as possible, tried to break DES. A number of "white hat" hackers also tested the system and reported on their successes. Still others attacked DES because they believed it had outlived its effectiveness and was becoming increasingly vulnerable. The sum total of these efforts to use all of the possible keys to break DES over time made for a brute force attack. In 1996, the supposedly uncrackable DES was broken. In this captivating and intriguing book, Matt Curtin charts DES’s rise and fall and chronicles the efforts of those who were determined to master it.
