This paper presents an improved matrix barcode to verify authenticity of products. In this scheme, the server use Java to generate reliable and secure keypairs, use public key to encrypt product information, then use the cipher text to generated Qrcode barcode, customers use handset to decode Qrcode barcode, get cipher text and transfer to manufacturer, and then verified through GPRS networks. The...
This paper presents an improved sign-in scheme base on public key cryptosystem. In the program, the client uses JavaScript to implement the RSA's encryption and decryption algorithms, using Java implement key pairs generation and management, encrypt and decrypt the ciphertext in server side, combine the above technologies to implement the scheme, and illustrate the key codes, as a result, it not only...
