And the gyroscope with accelerometers can be navigated without satellites and networks, a classic gyroscope application. Accelerometers can be used in applications with fixed gravity reference coordinate systems, linear or oblique motions, but rotational motion is limited to a certain range. When dealing with both linear and rotational motions, it is necessary to combine the acceleration with the gyroscope me

Finally, the original data is reduced to a value smaller than the CRC polynomial. This value is the 8-bit checksum. Figure 2 shows how to calculate the checksum.

The random degree of the password stream is not high, so there is a certain security risk. A completely random cipher stream, that is, one-time pad, is very secure, but it is extremely demanding to use it: 1. the cipher stream must be completely random; 2. The encrypted stream must be the same as the data to be encrypted. 3. The stream cannot be reused. Therefore, using a one-time passw

RSA is an asymmetric encryption algorithm. RSA is widely used in public key encryption standards and electronic commerce. RSA was proposed in 1977 by Ronald Rivest, Adi Shamir, and Leonard Adleman. Both of them were working at the Massachusetts Institute of Technology. RSA is a combination of the first letters of the three of them .. Net, we can use the encryption service
Recently, in the online QQ group, it is often said that "do not buy things of a" XX "company in the future, how much will be donated in the earthquake, and do not look at XX stars in the future, how much does a large earthquake donate ".
Many of these companies are foreign companies. It seems that the enemy of the Chinese people who donate less money is the enemy of the Chinese people. What a terrible idea! For example, if a person is homeless in the street and you used to pay him a dollar, he
In document [1], Shamir proposes an identity-based encryption (IBE) and signature scheme. Assume that a trusted key generation center (kgg) exists. The user selects the name (or network address, street address, street address, and telephone number) as the public key, the corresponding private key is calculated by kgg and allocated to each user on the network.
IBE is a bit similar to the ideal email system: if you know a person's name and address, you can send him a letter that can only be rea

It is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and is also popular. The algorithm is named by the inventor Ron Rivest, Adi Shamir, and Leonard Adleman. However, the security of RSA has never been proved theoretically. It has experienced various attacks and has not been completely cracked yet.
