Description

technical field [0001] The invention relates to the field of information technology, in particular to an information terminal and an information security device thereof. Background technique [0002] With the rapid development of the network economy today, information security is becoming more and more important, and more and more applications require encryption and decryption. [0003] When encrypting a message, using an encryption key (Encryption Key) is like using a key to lock a lock. When decrypting this message, the corresponding decryption key (Decryption Key) must be used. [0004] There are currently two main encryption algorithms: symmetric algorithms (Symmetric Algorithms) and public-key algorithms (Public-key algorithms, also called asymmetric algorithms Asymmetric Algorithms). Systems using symmetric algorithms are sometimes classified as Conventional. Symmetric algorithms are the most common type of encryption algorithm. They are called "symmetric" because ...
