Data Encryption is the process by encrypting the digital information system to the original, according to encryption algorithm transforms into a completely different and was plaintext digital information process. Suppose E is the encryption algorithm, D is the decryption algorithm, the mathematical expression of encryption and decryption of data is: P = D) data encryption technology can be divided into data encryption and data storage encryption. Data transmission encryption key is encrypted in the data stream, commonly used link encryption, encryption and end to end encryption nodes in three ways. Encrypted data transmission link is only in the physical layer data link layer before the encryption, regardless of the source and destination, it is used to protect data communications between nodes, the receiver is on the path of the station sending node, the information in within each node must be decrypted and re-encryption, in turn, until you reach the destination.
Open source movement that co-founder Bruce Perens, Linux software involved in this lawsuit. He said: "Obviously, this is the last 10 years we have been facing the situation of software patents. We do have their own defensive patents, may be useful at some point." Microsoft spokesman Michael Marinello played only re-emphasize this TomTom used only for proceedings Linux kernel, open source software "is not the focus of this action." This is the third time Microsoft patent infringement lawsuits, but Peren said: "This case can be very beneficial to us because in the end that the patent may not count." One of them, involving Windows95 version of the Microsoft FAT file system, called " A Common Namespace for Long and Short Filenames ", has been the U.S. Patent and Trademark Office determined invalid, but Microsoft has re-apply some of the patents. "Intellectual Property and Open Source", said Van Lindberg, author of Microsoft it is difficult to convince a judge other people involved in the patent is valid. He pointed out that another patent related to planting the car computer software, as early as 1999, Microsoft applied for the patent before, Linux system to be used in the car. Other patents may be invoked federal court ruling in 2008: to be regarded as abstractions of general business theory, the so-called "theory" franchise, to be limited.
