Tianjin subway station to Lujiazui Center

1. At present, only Metro Line 1 is open to traffic. The subway of Tianjin east station has not been repaired yet, but the public transportation in Tianjin is still well developed. There is a big bus stop in the east station, so it is suggested to take walking and public transportation as the main way to go to the above places... First, walk 300 meters to the right out of Tianjin station is the Italian style area, and walk 300 to 400 meters along Jiefang Bridge is the golden street and Binjiang Road, Ancient culture street can take 635 or 836 to Chengxiang east road or Gulou. It seems that there is no direct bus to Dabei temple. Even if you want to transfer, you have to take a part of the way. I suggest you take a taxi

3. As we all know, SHA-1 is not a secure cryptographic hash function. Researchers now believe that it is inevitable to find a pair of conflicting hash values (that is, two different input hashes result in the same hash value), which may appear in the next month. This poses a potential threat to the network, because nowadays many websites still use sha-1-based digital signature certificate. Fortunately, just finding a pair of conflicting hash values is not enough to forge digital certificates and break the network trust model
this article describes how to forge digital certificate by hash collision, and how certificate authority makes it more difficult for attackers to forge digital certificate by using random certificate serial number
digital signature is the cornerstone of trust
the Internet depends on trust. Whether you log in online banking or browse reddit, HTTPS always protects you by encrypting communication data and verifying website digital certificate. Most browsers will hang a lock on the address bar intuitively when they visit the website using HTTPS
when the target website has a digital certificate containing the owner's identity information and the host name, HTTPS can confirm the authenticity of the current website to the browser. A certificate is a small file with a digital signature issued by a trusted third party certification authority. For browsers, digital signatures are a source of trust. If your browser believes that the digital signature on the certificate is correct, it will trust the certificate. This system for identity authentication is called public key infrastructure (PKI)
if the digital signature cannot be trusted in the system, all systems relying on the digital signature will crash. For example, someone can forge a cloudflare.com certificate issued by a trusted Ca, and he can fake cloudflare.com to deceive visitors
digital signature is a string of numbers calculated based on message and public key. Each digital signature needs a public-private key pair and a hash function. The hash function is used to replace the message with a unique digest, the private key is used to sign, and the public key is used to verify the signature
for example, to create an RSA signature, you need to calculate the hash value of the message, and then use the private key to encrypt the calculated hash value. Anyone can verify whether the signature belongs to you and the authenticity of the message. We only need to obtain the public key, then decrypt it, and compare the decryption value with the hash value of the source message. If the two values match, we think that the digital signature is correct.

4. Collision is not happy to encounter things, do not think, so all attention to have the wrong to recover

6. The track laying of line 9 from Zhongshan Gate station to Dagu West Road station has been completed, and the catenary was electrified in December last year. The track laying of the left line from Dagu West Road station to Qijing Road Station (Dawangzhuang station) has also been completed
it is expected that shiyijing road to Donghai Road will be put into trial operation this summer
however, the biggest bottleneck of line 9 is Tianjin station, which is a node. Not only line 9 passes through, but also lines 2 and 3
the construction progress of Nankai and Xiqing sections of line 2 is much slower than that of Hedong, and the shield construction has not yet started
the construction progress of Hebei and Beichen sections of line 3 is much slower than that of Nankai, and Xiaodian parking lot has not started yet
therefore, the progress of line 9 is not his own problem. There are also problems of line 2 and line 3. The construction site of the square behind Tianjin railway station is busy every day, which is also to complete the project as soon as possible. But it is certain that line 9 should be put into operation together with lines 2 and 3
line 9 will be put into trial operation this year from Zhongshan Gate station to shiyijing Road station
the whole line should be open to traffic together with line 2 and line 3 in the first half of 2012.

7. Metro Line 2, about 50 minutes / 16.2 km
Tianjin Binhai International Airport
walk 1.3km to Binhai International Airport Station

take Metro Line 2 (Caozhuang direction) 9 and get off at Tianjin station

8. Tianjin metro station (Metro Jinbin light rail, Metro Line 2, Metro Line 3)

can enter at the north square of Tianjin station or the exit of underground station, at the northwest corner.

9. Get off at Lujiazui Station of Metro Line 2, exit at Exit 1, cross the road with pedestrian overpass, turn right, walk along Lujiazui ring road to the northeast, turn left at Dongyuan intersection, and walk west along Dongyuan road to Binjiang Avenue.
