System and method for temporary password management

1. A computer-implemented method of passwords management, the method comprising:

obtaining, by a password management entity, a request to login a local device into an authentication authority;

generating, by the password management entity, a temporary password;

generating, by the password management entity, based on the temporary password, a set of at least K+1 pairs of input and output values of a polynomial of degree K, wherein TP 1 includes a portion of pairs of input and output values of the polynomial, and wherein TP 2 includes the other pairs of input and output values of the polynomial, and wherein the temporary password can be determined based on the TP 1 and the TP 2 ;

sending, by the password management entity, the temporary password to the authentication authority;

sending, by the password management entity, the TP 1 and the TP 2 to a user device;

using, by the user device, the TP 1 and the TP 2 to identify the polynomial;

after identifying the polynomial from the at least K+1 pairs, applying, by the user device, a function to at least one coefficient of the polynomial to generate the temporary password; and

providing the temporary password from the user device to the local device;

obtaining, at the authentication authority, the temporary password from the local device;

comparing, by the authentication authority, the temporary password obtained from the local device with the temporary password obtained from the password management entity; and

authorizing the login if a match is found.

2. The method of claim 1 , further comprising:

sending, by the password management entity, the value TP 1 to the user device over a first secured communication channel; and

sending, by the password management entity, the value TP 2 to the user device over a second secured communication channel.

3. The method of claim 2 , further comprising:

sending the temporary password from the user device to the local device using an out-of-band channel.

4. The method of claim 1 , further comprising:

sending, by password management entity, the value TP 1 to authentication authority over a first secured communication channel;

sending, by password management entity, the value TP 2 to the authentication authority over a second secured communication channel; and

combining the values TP 1 and TP 2 by the authentication authority to arrive at the temporary password.

5. The method of claim 1 , wherein K=1 and:

the TP 1 includes a first pair of input and output values of the polynomial, and the TP 2 includes a second pair of input and output values of the polynomial.

6. The method of claim 1 , further comprising:

deleting the temporary password from the authentication authority after comparing.

7. The method of claim 1 , further comprising:

storing the temporary password on the local device.

8. A computer-implemented method of passwords management, the method comprising:

obtaining, by a password management entity, a request to login a local device into an authentication authority;

generating, by the password management entity, a temporary password;

generating, by the password management entity, based on the temporary password, a set of at least K+1 pairs of input and output values of a polynomial of degree K, wherein TP 1 includes a portion of pairs of input and output values of the polynomial, and wherein TP 2 includes the other pairs of input and output values of the polynomial, and wherein the temporary password can be determined based on the TP 1 and the TP 2 ;

sending, by the password management entity, the temporary password to the authentication authority;

sending, by the password management entity, the TP 1 to the user device over a first secured communication channel;

sending, by the password management entity, the TP 2 to the local device over a second secured communication channel;

sending the TP 1 from the user device to the local device using out-of-band channel; and

using, by the local device, the TP 1 and the TP 2 to identify the polynomial;

after identifying the polynomial from the at least K+1 pairs, applying, by the local device, a function to at least one coefficient of the polynomial to generate the temporary password;

obtaining, at the authentication authority the temporary password from the local device;

comparing, by the authentication authority, the temporary password obtained from the local device with the temporary password obtained from the password management entity; and

authorizing the login if a match is found.

9. A system for temporary passwords management, the system comprising:

a memory;

a user device;

a processor configured to:

obtain a request to login a local device into an authentication authority;

generate a temporary password;

generate, based on the temporary password, a set of at least K+1 pairs of input and output values of a polynomial of degree K, wherein TP 1 includes a portion of pairs of input and output values of the polynomial, and wherein TP 2 includes the other pairs of input and output values of the polynomial, and wherein the temporary password can be determined based on the TP 1 and the TP 2 ;

send the temporary password to the authentication authority;

send the TP 1 to the user device over a first secured communication channel;

send the TP 2 to the user device over a second secured communication channel;

wherein the user device is configured to:

use the TP 1 and the TP 2 to identify the polynomial; and

after identifying the polynomial from the at least K+1 pairs, generate the temporary password based on a function applied to at least one coefficient of the polynomial;

provide the temporary password from the user device to the local device;

wherein the processor is further configured to:

obtain the temporary password from the local device;

compare the temporary password obtained from the local device with the temporary password obtained from the password management entity; and

authorize the login if a match is found.

10. The system of claim 9 , further comprising the user device:

wherein the user device is configured to:

combine the TP 1 and the TP 2 to arrive at the temporary password; and

send the temporary password to the local device using an out-of-band channel.

11. The system of claim 9 , further comprising the user device, wherein K=1 and:

the TP 1 includes a first pair of input and output values of the polynomial and

the TP 2 includes a second pair of input and output values of the polynomial.

12. The system of claim 9 , further comprising the authentication authority:

wherein the processor is further configured to:

send the value TP 1 to the authentication authority over a first secured communication channel;

send the value TP 2 to the authentication authority over a second secured communication channel; and

wherein the authentication authority is configured to:
