"sicp?2.1 Data Abstract Introduction" look uncomfortable, spit trough a bit.The basic idea of data abstraction was to structure the programs that was to use compounddata objects so that they The operate on ' abstract data. ' Interface operates on an abstraction.At the same time, a "concrete" data representation is defined independentof the programs, the data. The interface between these and parts of Oursystem would be a set of procedures, calledselectors and construct ORS, that's implement theab

RC4 as an example, two evp_cipher structures of RC4 are defined, but the key length is different, one is a 128-bit (16-byte Key), the other is a 40-bit (5-byte Key), and the algorithms are the same: # ifndef openssl_no_rc4 # include # Include "cryptlib. H" # Include # Include # Include # Define evp_rc4_key_size 16 // This structure is unique to each encryption algorithm, and each algorithm has its own // T

with during transmission. The standard does not describe how the key was built. In practice, most facilities share a single key between all mobile stations and access points. More complex key management techniques can help prevent the attacks we describe; However, as far as we know, there is no commercial product to support this technology.The following two sections describe the problems in the protocol and the technical details of the attack. This assumes that the reader has some background kn

Study Notes for the tool (2.1.1 ~ 2.1.3)Zhou yinhui These sections are relatively simple. They mainly introduce some ideas such as "abstraction" and "encapsulation". The author has spent a lot of pen and ink to inject the "abstraction" idea into the reader's mind, however, if you have learned some Object-Oriented Programming before, these sections can be quickly passed (except for 2.1.3, some of the content in this section will be well written, and I will talk about it later) 1. Practice

With the continuous development of wireless networks, multi-Stream Aggregation (MSA, Multiple Stream Aggregation) can improve the edge throughput by 500% through deep fusion of Multi-standard, multi-carrier and multi-layer networks, realizing the concept of borderless networks enables users to enjoy high-speed and stable data access services wherever they are on the network. It will become a key technology for network evolution in the future. The popularity of smart terminals and the rapid devel

MCI commands), the device can complete various functions, you do not have to worry about the internal implementation of the device. For example, for play, the video and CD machines have different responses (one is playing a video and the other is playing audio), but for users, they only need to press the same button.Usage of MCI The application controls the media device by sending commands to the MCI. The MCI command interface can be divided into command strings and command messages, which have

The Chinese zodiac represents 12 animals that represent the birth of people, that is, rats, cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs, and pigs. If the person born in the Year of Yin belongs to the tiger, the person born in the Year of Mao belongs to the rabbit. The Chinese zodiac, also known as the "genus", is a unique way to indicate the birth time of Chinese people, it is equivalent to the western zodiac signs (pisces, Aries, Taurus, Gemini, cancer, Leo, f

Common HTTPS attack methods0x00 background Study common https attack methods Beast crime breach, and puts forward some suggestions for secure deployment of https Based on https features. HTTPS attacks are mostly used in man-in-the-middle attacks. They are mainly used to perform side-channel-attack Based on the compression algorithm used by HTTPS and the CBC encryption mode. The prerequisites for these attacks are harsh, and the victim host must submit many requests to collect sufficient informa

technologies, but they are not added to the new kernel. In these cases, You have to patch your kernel (the premise is that there is a patch ). Now, I assume you have downloaded the corresponding patch. Here we will replace patch.bz2. Put it in the/usr/src directory, and then use the following command to make it take effect: Bzip2-DC/usr/src/patch.bz2 | patch-P1-dry-run Bzip2-DC/usr/src/patch.bz2 | patch-p1 Note! At this time, you should always be in the/usr/src/Linux directory. The fi

The first command is only experimental, and does not change your source code. If no error message is generated, you can use the second command to generate a true patching action for the source code. If the First Command has an error, please do not continue to execute it to see where the error is. Similarly, you can provide pre-patches to your kernel. For exam
