Secure Seed-Based Sturdy OTP via Convenient Carry-on Device

摘要

The Internet users for the purpose of easy memorizing select a weak password and reuse it along many Web sites vulnerable to password stealing and reuse due to rapid growth of cloud computing. Sturdy one-time password (S-OTP) provides with easy remembrance and prevention of password reuse using personal Android mobile phone without the necessity of sending an SMS and can be integrated into any original user authentication system without contradicting the overall security. Also, in the worst cases, if the mobile phones are stolen, it is made unfeasible by means of two-dimensional SHA3 and MD5 forward hashing with unique and secure hard-coded seed information from mobile device.
