What is the meaning of digital certificate in digital currency
Digital certificate is a series of numbers that mark the identity information of all parties in Internet communication. It provides a way to verify the identity of communication entities on the Internet. Digital certificate is not a digital ID card, but a seal or seal (or a signature added on the digital ID card) on the digital ID card
it is issued by Ca organization, also known as certificate authority center. People can use it to identify each other on the Internet
digital certificate is an authoritative electronic document, which can be issued by an authoritative and impartial third party organization, i.e. Ca (for example, CA companies in various parts of China), or by an enterprise level CA system

functions of digital certificate:
1. Confidentiality of information
business information in transaction has confidentiality requirements. If the account number and user name of the credit card are known, it may be stolen. If competitors know the order and payment information, they may lose business opportunities. Therefore, in the information dissemination of e-commerce, there are universal encryption requirements
2. The certainty of the trader's identity
the two sides of the online transaction are likely to be strangers, thousands of miles apart. In order to make the transaction successful, first of all, we must be able to confirm the identity of the other party. For businesses, we should consider that customers can not be fraudsters, and customers will worry that online stores are not black shops of fraud. Therefore, convenient and reliable confirmation of the identity of the other party is the premise of the transaction
Non repudiation e to the changing business environment, once the transaction is completed, it cannot be rejected. Otherwise, it will inevitably damage the interests of one party. For example, when ordering gold, the price of gold is lower, but after receiving the order, the price of gold rises. If the receipt can deny the actual time of receiving the order, or even the fact of receiving the order, the orderer will suffer losses. Therefore, every link in the process of electronic transaction communication must be undeniable4. Non modifiability
transaction documents are not modified, such as the above gold orders. When the supplier received the order, he found that the price of gold rose sharply. If we can change the content of the document and change the order number from 1 ton to 1 gram, we will greatly benefit, so the ordering unit may suffer losses. Therefore, in order to ensure the seriousness and fairness of transactions, electronic transaction documents should also be irrecible

what is digital certificate
digital certificate is a series of data that marks the identity information of all parties in Internet communication. It provides a way to verify your identity on the Internet, and its function is similar to the driver's license or ID card in daily life. It is issued by an authoritative organization - Ca organization, also known as certificate authority y center. People can use it to identify each other on the Internet
why should we use digital certificate
the e-commerce system technology based on Internet makes it extremely convenient for online shopping customers to obtain the information of businesses and enterprises, but it also increases the risk of abuse of some sensitive or valuable data. Both the buyer and the seller must be truthful and reliable in all financial transactions concted on the Internet, and must make the customers, merchants and enterprises have absolute confidence. Therefore, the Internet e-commerce system must have reliable security technology, that is to say, the four elements of network security must be guaranteed, That is, the confidentiality of information transmission, the integrity of data exchange, the non repudiation of sending information, and the certainty of the identity of traders
1. Confidentiality of information
all business information in the transaction should be kept confidential. If the account number and user name of the credit card are known, they may be embezzled. If the ordering and payment information is known by competitors, they may lose business opportunities. Therefore, in the information dissemination of e-commerce, there are generally encryption requirements
2. The certainty of the identity of the trader
the two sides of the online transaction are likely to be strangers, thousands of miles apart. In order to make the transaction successful, we should first confirm the identity of the other party. For businesses, we should consider that the client can not be a liar, and customers will worry that the online store is not a black shop playing with fraud. Therefore, it is the premise to confirm the identity of the other party conveniently and reliably. For banks, credit card companies and sales stores that provide services for customers or users, in order to carry out service activities safely, confidentially and reliably, identity authentication should be carried out. For the relevant sales stores, they do not know the number of the credit card used by the customers. The store can only give the confirmation of the credit card to the bank. Banks and credit card companies can use a variety of confidentiality and identification methods to confirm whether the customer's identity is legal. At the same time, they should also prevent the occurrence of non payment and confirm the order and order receipt information< 3. Non repudiation
e to the ever-changing business situation, once a transaction is concluded, it cannot be denied. Otherwise, the interests of one party will be damaged. For example, when ordering gold, the price of gold is lower, but after receiving the order, the price of gold rises. If the receiving party can deny the actual time of receiving the order, or even the fact of receiving the order, the ordering party will suffer losses. Therefore, every link in the process of electronic transaction communication must be undeniable
4. Immutability
transaction files cannot be modified, such as ordering gold in the above example. After receiving the order, the supplier finds that the price of gold has increased significantly. If he can change the content of the document and change the order quantity from 1 ton to 1 gram, he will benefit greatly, and the ordering unit may suffer losses. Therefore, electronic transaction documents should also be non modifiable to ensure the seriousness and fairness of transactions
while lamenting the great potential of e-commerce, people have to think calmly about how to ensure the fairness and security of the transaction and the authenticity of the identities of both parties when they conct transactions and operations on the computer Internet where people do not meet each other. There is a mature security solution in the world, that is to establish a security certificate architecture. Digital security certificate provides a way to verify identity on the Internet. The security certificate system mainly adopts the public key system, and other technologies include symmetric key encryption, digital signature, digital envelope and so on
we can use digital certificate to establish a set of strict identity authentication system by using symmetric and asymmetric cryptosystems and other cryptographic technologies, so as to ensure that the information is not stolen by others except the sender and receiver; Information will not be tampered in the process of transmission; The sender can confirm the identity of the receiver through the digital certificate; The sender cannot deny his own information

digital certificate is the certificate issued by Ca Organization (that is, the CA certificate mentioned in the question), which contains the public key, the name of the owner of the public key, the digital signature of Ca, the period of validity, the name of the authorization center, the serial number of the certificate and other information. We can easily understand that digital certificate is the ID card of an indivial or enterprise on the network
in the process of using digital certificate, the application of encryption technology can achieve:
< UL >identity authentication: the two sides who transmit information in the network can not meet each other, and the use of digital certificate can confirm the identity of both sides, rather than others pretending
confidentiality: by using digital certificate to encrypt information, only the receiver can read the encrypted information, so as to ensure that the information will not be stolen by others
integrity: digital certificate can be used to verify whether the information transmitted has been tampered or lost in the process of transmission
non repudiation: digital signature using digital certificate can accurately mark the signer's identity and verify the signature content, so the signer has non repudiation to the signature and signature content, and its effect is the same as handwritten signature
Digital certificate is a series of numbers that mark the identity information of all parties in Internet communication. It provides a way to verify the identity of communication entities on the Internet. Digital certificate is not a digital ID card, but a seal or seal (or a signature added on the digital ID card) on the digital ID card
there are many numbers and English in the digital certificate, which bind the public key and the real identity of its holder. When using digital certificate for identity authentication, it will randomly generate 128 bit identity code. Each digital certificate can generate corresponding but not the same number every time, so as to ensure the confidentiality of data transmission, which is equivalent to generating a complex password

, in order to avoid potential security problems such as certificate loss caused by improper usage in the traditional digital certificate scheme, Alipay creatively launched a al certificate solution: Alipay members will receive two certificates at the same time when applying for digital certificates, one for Alipay account verification. The other one is used to verify the computers currently used by members
the second certificate cannot be backed up. Members must apply for a new one for each computer. In this way, even if a member's digital certificate is illegally stolen by others, his account will not be lost
payment shield is a physical security tool similar to USB flash disk. Its built-in micro smart card processor can block all kinds of risks and keep your account in a safe environment. At present (June 2015), the way to ensure the security of e-mail is digital certificate
in order to ensure the security and confidentiality of electronic transactions and payments on the Internet and prevent fraud in the process of transactions and payments, the Internet e-commerce system technology enables online shopping customers to easily obtain the information of businesses and enterprises, We must establish a trust mechanism on the Internet. This requires that buyers and sellers who participate in e-commerce must have a legal identity and be able to be verified effectively on the Internet. Digital certificate is an authoritative electronic document. It provides a way to verify your identity on the Internet, which is similar to the driver's license or ID card in daily life. It is issued by an authoritative organization, CA certificate authority. People can use it to identify each other in Internet communication. Of course, in the process of digital certificate authentication, certificate authority (CA) as an authoritative, fair and reliable third party, its role is crucial
digital certificates must also be unique and reliable. In order to achieve this goal, many technologies are needed. Generally, digital certificate adopts public key system, that is, a pair of matching keys are used to encrypt and decrypt. Each user sets a specific private key (private key) which is only owned by himself, and uses it to decrypt and sign; At the same time, a public key (public key) is set and disclosed by the user, which is shared by a group of users for encryption and signature verification. When sending a confidential file, the sender uses the public key of the receiver to encrypt the data, while the receiver uses its private key to decrypt the data, so that the information can arrive at the destination safely. The encryption process is an irreversible process by digital means, that is, only private key can be used to decrypt. Public key technology solves the management problem of key distribution. Users can publish their public key and keep their private key
the process of digital certificate issuing is generally as follows: users first generate their own key pair, and then transfer the public key and part of personal identity information to the certification authority. After verifying the identity, the authentication center will perform some necessary steps to make sure that the request is actually sent by the user. Then, the authentication center will issue the user a digital certificate, which contains the user's personal information and his public key information, and also contains the signature information of the authentication center. Users can use their own digital certificate for various activities. The digital certificate is issued by an independent certificate authority. Digital certificates are different, and each certificate can provide different levels of credibility. You can obtain your own digital certificate from the certification authority
at present, the types of digital certificates mainly include: personal digital certificate, company digital certificate, company employee digital certificate, server certificate, VPN certificate, WAP certificate, code signature certificate and form signature certificate

digital signature is a typical application of asymmetric encryption algorithm. The application process of digital signature is that the sender of data source uses its own private key to encrypt the data checksums or other variables related to the data content to complete the legal "signature" of the data. The receiver of data uses the public key of the other party to interpret the received "digital signature", and uses the interpretation results to test the integrity of the data, To confirm the validity of the signature. Is digital signature technology in network system? B
