The system proceeds to block 570 where the ACS receives the AWK encrypted PINBLOCK from the HSM2 and communicates the AWK encrypted PINBLOCK to an issuer for authentication. The ACS may send, for example, the AWK encrypted PINBLOCK to an IPGS. Ic-prog software 1.05d. The IPGS may communicate the AWK encrypted PINBLOCK to the issuer for authentication.

In one embodiment, the invention provides for processing token transactions, including receiving an encrypted password for a debit card transaction, wherein the password was secured using encrypted debit-card information, decrypting the password using encrypted debit-card information for the debit card, recreating the password using actual debit-card information for the debit card, and forwarding the recreated password for subsequent transaction processing. The invention is suitable for implementation with other types of tokens in addition to debit-card tokens as well. The invention can be implemented in a scenario where the password includes a PIN block that is created by combining a clear or encrypted PIN for the token with token information.
