Mining strategy of Ares virus
I worked on a project in the Bay over there for a year, and many tourists were cheated
in fact, the free beach you mentioned should be the parking lot. It's a short way to get in from the parking lot (next to Holiday Inn). There are many vendors on the side. It's OK to go in without buying anything. It's a free beach (it's also the underwater world diving base. The charge is relatively high. It's the same in Sanya, so it's OK not to play)
another location is the central square. It really costs about 40 yuan. In fact, it's a joint ticket for two scenic spots: the Shell Museum on the ground floor of the central square and the Butterfly Valley in the bay. Only by buying this ticket can you enter the same free beach from the central square. Hehe, it's a bit of a forced purchase. So if you don't want to spend money, you can enter the free beach from the parking lot on the other side of the underwater world, which is connected with the beach in the central square, one kilometer away
there are many ways to get to the beach. The distance from the central square to the underwater world is more than one kilometer from the green belt of the coastal park. There are several openings that are easy to walk directly down to the beach. If there is a hotel, you can walk directly through the hotel lobby to get to the beach. (ha ha, as long as you don't dress like a migrant worker, the waiter over there is very polite to show you the way.)
Yalong Bay Beach basically has a beach chair for every walk, but it is only for hotel guests free of charge, if not for hotel guests, there is a charge. Many people choose Yalong Bay as a pure leisure resort. They sleep in the hotel, eat, watch the sea, play on the beach and go swimming. Of course, they can also choose to participate in several scenic spots. This is also according to their hobbies. There is no best way to go on holiday, only suitable for their own way to go on holiday, suitable for their own is the best.
Onion routing network uses asymmetric encryption. The sender obtains a public key from the directory node, encrypts the message to be sent and sends it to the first node in the chain, which is also called the entry node; Then create a connection and share a key with it. After the connection is created, the sender can send the encrypted message to the second node on the chain through this connection. Only the second node can decrypt the message
when the second node receives this message, it will create the same connection as the previous node, that is, the entry node, to extend the sender's encrypted connection to it, but the second node does not know the identity of the previous node in the chain
Then, according to the same principle, the sender sends the message that only the third node can decrypt to the third node through the encrypted connection between the entry node and the second node, and the third node also creates a connection with the second node; By repeating the same steps, the sender can generate a longer and longer connection, but there are still performance limitationswhen all the connections on the chain are created, the sender can send data through it and keep anonymity. When the destination sends back the data, the nodes in the chain will send back the data through the same connection, and encrypt the data layer by layer, but the encryption order is completely opposite to that of the sender; When the original sender receives the data returned from the destination, there is only the innermost layer of encryption left. At this time, the message returned from the destination can be obtained by decrypting it

the weakness of onion routing
although messages are encrypted layer by layer in onion routing network, at the exit node, the node will decrypt the last layer and send the original message to the receiver; Therefore, if the exit node is attacked or controlled, the original message will be intercepted
Swedish researcher Dan & Chen 8231; Eagstad (Swedish: Dan egersta) has used this method to obtain more than 100 e-mail passwords sent to foreign embassies
The principle of exit node vulnerability is similar to that of unencrypted wireless network, the latter means that users may be intercepted by others when they transmit unencrypted data on the wireless network; These two problems can be solved through end-to-end encrypted connection, such as SSL, HTTPS and so on
