Abstract
A method for purchasing items over a non-secure communication channel uses a secure communication device. The secure communication device includes a host processor, a secure memory that includes a laser-scribed encryption key, and a non-secure memory for storing encrypted data. A user's sensitive data is encrypted within the secure memory using the laser-scribed encryption key and stored as encrypted data in the non-secure memory. An encrypted credit card number and an encrypted secret key is retrieved from the non-secure memory, the encrypted credit card and secret key are decrypted with the laser-scribed encryption key, the credit card number is encrypted with a session key, and the encrypted credit card number is transferred over the network to a destination such as an internet vendor.
