This paper presented the design of an RSA encryption and tokenization-based system for combating fraud on online credit card transactions.
RSA encryption is generally slightly faster than ECC, while ECC decryption may be several times faster than RSA, although both are generally efficient enough not to provide a practical system bottleneck [15, 16].
ECC can achieve strong encryption using keys of shorter bit length than would be needed for comparable security using RSA encryption. Research will focus on the implementation of a "naive" elliptic curve cryptosystem, which can be incrementally improved through algorithm optimization.
Therefore, RSA encryption method was replaced, in this research, by ECC.
The virus reportedly encrypts files with various extensions including, but not limited to: .doc, .txt, .pdf, .xls, .jpg, .png, .cpp, .h and more using an RSA encryption algorithm with a 1024-bit key.
The users' data transmissions and activities are encoded with 2048-bit RSA encryption and secured with password-protection, and files can be opened, updated and saved without leaving a trace on the device used.
