Abstract
The invention provides a cryptographic method which includes receiving at a first entity a second public key M. At least one of a first session key Kand a first secret Smay be generated based on the second public key M. A first random nonce Nmay be generated which may be encrypted with at least one of the first session key Kand the first secret Sto obtain an encrypted random nonce. The encrypted random nonce may be transmitted from the first entity. In response to transmitting the encrypted random nonce, the first computer may receive a data signal containing a modification of the first random nonce N. If the modification of the first random nonce Nwas correctly performed, then at least one of (i) opening a communication link at the first computer, and (ii) generating a first initialization vector Iis performed.
