First, the principle:CTR Mode is a stream cipher that generates a key stream by encrypting successive accumulated counters, and in CTR mode, each packet corresponds to a successive cumulative counter, and the key stream is generated by encrypting the counter. The final cipher packet is obtained by XOR the bit sequence encrypted by the counter and the plaintext packet.Second, schematic diagram:Three, the advantages of CRT mode:1, the hardware efficienc

one block added T o the message. For 8byte ciphers-like DES, we-then has a block of length 8b filled completely with 8s.AES CBC plus decryption principleCBC plus decryption principle as shown, image source WikipediaCBC encryption principle: PlainText with vector xor, and then encrypted with key, as the result of the next block initialization vector. Decryption principle: Use the key to decrypt the ciphertext first, decrypt and then the original vector will be different or clear.CBC needs to pad

IndexAd click-through rate estimation is a very important component of the programmatic AD trading framework, and the CTR is estimated to have two levels of indicators:1. Sort the indicator. The sort indicator is the most basic indicator, it determines whether we have the ability to find the most suitable ads to show to the most appropriate users. This is the basis for monetization, and technically, we measure it with the AUC.2. Numerical indicators.

Recently we are in the development of a project, one of the requirements is the statistical site click-through rate, for clicking on the timeliness of the front-end framework we are using Nodejs+redis this way, data organization through Zset and keywords to split, each manuscript corresponding to a Zset record, through score Increase to count each manuscript click-through, later in the through net MQ synchronization to the relational database, Redis is the keyvalue database to the relational row

The DEEPFM proposed for cross (high-order) feature learning is a end-to-end model that does not require the artificial construction of features on the wide side like Widedeep.Network structure:Structure of sparse features: Class-type feature one-hot, continuous-type feature numerical representation, or segmented discrete one-hotAfter FM and nn output prediction y respectively, the two results are sigmoidFM section:Paper pointed out that in the case of sparse data, FM can still effectively learn
