    • The claimed subject matter relates to an architecture or arrangement that can limit access to sensitive information by means of encryption. In particular, data obtained from a payment instrument at, e.g., a Point-Of-Sale (POS) location can be encrypted at an early stage such that a POS (or another) application does not have access to the data in an unencrypted form and/or does not have access to a means for decrypting the data. For example, a Public Key Infrastructure (PKI) arrangement can be employed such that a back-end payment processor can define encryption algorithms, associate itself with a public key, and maintain a private key for decryption. The public key can be delivered to the POS location and employed for data encryption, and, moreover, the PKI can be regulated by the more trusted parties.
    • 所要求保护的主题涉及可以通过加密来限制对敏感信息的访问的架构或布置。 特别地,可以在诸如销售点(POS)位置处的支付工具获得的数据在早期阶段被加密,使得POS(或另一)应用程序不以未加密的形式访问数据 和/或不能访问用于解密数据的手段。 例如,可以使用公共密钥基础设施(PKI)布置,使得后端支付处理器可以定义加密算法,将其自身与公钥相关联并且维护用于解密的私钥。 公钥可以发送到POS位置并用于数据加密,此外,PKI可以由更多的信任方来管理。
