Please contact CardLogix directly for more details. Triple-DES is a method of using DES to provide additional security. Triple-DES can be done with two or with three keys. This algorithm uses two keys, called the private key . These keys are mathematically linked.
Asymmetric algorithms are typically stronger than a short key length symmetric algorithm.
But because of their complexity they are used in signing a message or a certificate. They not ordinarily used for data transmission encryption. As the card issuer, you must define all of the parameters for card and data security. The safest systems employ both methodologies. Because of this, straight memory cards can be used very cost-effectively for many systems.
