Abstract
A process may be utilized for securing unlock password generation and distribution. A first set of exclusive responsibilities, assigned to a trusted authority, includes random generation and encryption of an unlock password to compose a randomly generated encrypted unlock password. Further, a second set of exclusive responsibilities, assigned to a security agent, includes sending information associated with the unlock password and a digital signature of information associated with the unlock password to a communication device configured for a network in order to mate the unlock password to the communication device, and sending the randomly generated and encrypted unlock password along with mating data to a password processing center. In addition, a third set of exclusive responsibilities, assigned to a password processing center, includes decrypting the randomly generated and encrypted unlock password.
