Encryption keyboard is a special design of the keyboard, mainly used in the need for high security occasions, such as ATM, self-service terminals and other financial equipment. It encrypts data during the input process to ensure that sensitive information entered by users (such as passwords, PIN codes, etc.) is not illegally stolen or leaked. Ordinary encryption keyboard It only supports a variety of encryption algorithms, such as DES, AES, RSA, etc., but the high-security password keyboard, in addition to supporting algorithms, it also has many security protection mechanisms to prevent the leakage of sensitive information. Here is an introduction to encrypted keyboards:
Definition and features of the encryption keyboard:
- Definition:The encryption keyboard is a keyboard with the encryption function. It can automatically encrypt the password when the user enters the password, preventing the password information from being intercepted in plain text.
- Features：
- Automatic encryption：Sensitive information such as the password entered by the user is automatically encrypted inside the keyboard to ensure the security of information transmission.
- Physical security：It is usually made of strong metal and a series of specially designed technical means to cope with harsh environments and prevent physical attacks.
- Meet the standard：is certified by authoritative organizations such as the (Payment Card Industry )Security Council (PCI) and complies with the payment card industry security standards.
Working principle
The working principle of the encrypted keyboard mainly involves the following aspects:
- Encryption algorithm:International standard encryption algorithms such as DES/TRIDES and RSA are used to encrypt the entered password.
- Secure storage：Encrypted data is usually stored in a secure chip or memory to prevent the data from being accessed illegally or tampered with.
- Data transmission: Encrypted data is transmitted to the server or terminal through a secure channel, ensuring the security of data transmission.
Application field
Encrypted keyboards are widely used in situations requiring a high degree of security, mainly including:
- Financial equipment: such as ATM machines, CDM machines, ADM machines, automatic deposit machines, self-service cargo collection machines, self-service payment machines, self-service ticket machines, etc.
- Self-service terminal: such as telephone enquiry machine, self-service information machine, public telephone, etc.
Environmental adaptability
Encryption keyboards usually have good environmental adaptability to adapt to a variety of harsh working environments. For example, the operating temperature range of the encrypted metal keyboard can reach -25 ° C to +65 ° C, the relative humidity range is 30% to 90%RH (no condensation), and the storage temperature range can reach -40 ° C to +85 ° C.
security of authentication
The security of the encrypted keyboard has been certified by the authority. PCI certification is one of the highest standards of security certification in the payment card industry. It carries out strict and meticulous testing from six aspects: physical security, logical security, online security, offline security, equipment security management during production, and equipment security management before initial key injection. PCI Security Council certified encrypted keypad to ensure payment card device security and prevent user information leakage.
To sum up, the encryption keyboard is a special keyboard that encrypts data automatically during the input process, and is widely used in financial equipment and self-service terminals that require high security. By using advanced encryption algorithms and secure storage technology, it ensures that sensitive information entered by users is not illegally stolen or leaked.
