Abstract

A system and method for authentication including verifying a password is disclosed. In one embodiment, the authentication system includes a first storage unit to store an authentication sequence and a read-only memory unit to store an authentication algorithm. A microcontroller is coupled to the first storage unit, the read-only memory unit, and is configured to be coupled to and uncoupled from a host. The microcontroller is configured to execute the authentication algorithm to verify a password with the authentication sequence, and to send an access request to a web server via the host if the authentication algorithm has verified the password with the authentication sequence.

Claims

1. A system comprising:

a first storage unit configured to store an authentication sequence;

a read-only memory unit configured to store an authentication algorithm; and

a microcontroller coupled to the first storage unit and the read-only memory unit, and configured to be coupled to and uncoupled from a host and configured to execute the authentication algorithm to verify a password with the authentication sequence;

the microcontroller further configured to send an access request to a web server via the host if the authentication algorithm has verified the password with the authentication sequence.

2. The system of claim 1, further comprising a universal serial bus (USB) connector for coupling the microcontroller to the host.

3. The system of claim 1, further comprising a second storage unit coupled to the microcontroller.

4. The system of claim 3, wherein the microcontroller enables the host to access data stored in the second storage unit upon verification of the password with the authentication sequence.

5. The system of claim 3, wherein the microcontroller is further configured to receive data from the web server via the host and to store the data from the web server in the second storage unit.

6. The system of claim 3, further comprising an encoder coupled to the microcontroller, the encoder configured to encrypt data received from the web server.

7. The system of claim 3, further comprising an encoder coupled to the microcontroller, the encoder configured to decrypt data received from the web server.
