Publication number: 20220210137Abstract: A system and a method for securely transmitting electronic information, which encrypt an electronic information before the electronic information is transmitted between information nodes and decrypt the encrypted electronic information after the encrypted electronic information is received. Therefore, it is difficult to crack the encrypted electronic information even if the encrypted electronic information is stolen during a transmission process, whereby the electronic information is securely transmitted. At the same time, by means of signing and verification, the unit that receives the electronic information can determine whether the received electronic information is from the correct unit, and it can also ensure that only the correct receiving unit can use the electronic information, whereby the integrity of data verification is achieved. Therefore, the invention provides a process of confidentiality and integrity and has more applicability than the prior art.Type: ApplicationFiled: December 24, 2020Publication date: June 30, 2022Inventor: YU-CHENG LAI
