Abstract

Providing an electronic message includes constructing a first digital signature of the message and a personal secret known only to a sender of the message, constructing a second digital signature of the first digital signature and the message, and sending to a receiver the message, the first digital signature, and the second digital signature. The personal secret may be initially generated by the sender. The personal secret may be a pseudo-random number. The receiver may archive the message, the first signature, and the second signature. In response to a challenge, the message and the first and second signatures sent with the message may be compared using first and second signatures reconstructed by the sender. In response to at least one of the message and the first signature not matching, the message may be repudiated. Otherwise, the message may be validated. The sender may be a cell phone.
