Method and System of One-Time Password Authentication Scheme Provide Enhanced Randomness

摘要

seed (Seed), and use that value in the order of one-time passwords exposure value may be used for one-time passwords that random one-time password technology is used on the value of the one-time password to be used the next time to avoid being exposed, an attacker by using a random value every time passwords for authentication is not possible to infer the following values, and random passwords themselves to the server I value and generate one-time passwords using a synchronized timestamp value without transmitting Establish a configuration to increase the low frequency and randomness of communication. By registering and using one-time password authentication methods and systems that enhance the randomness, as described above, the non-synchronized methods and synchronized manner to generate a one-time password via the time value without transfer of the combination approach to quality and value, blend it, communication times it is possible to obtain a reduction, can be generated by using the hash table to prevent optionally infers the value of the one-time password to be used the next time. ;
