    • Secure activation of stored value cards at a point of distribution uses a portable activation secure application module (ASAM) within the card dispensing machine to activate each card. Each card has a standard user mode and a security user mode. In the standard user mode the card is activated and ready for use. In the security user mode the card is not active and cannot be used to make a purchase. An issuer supplies an issuer activation key to a card supplier who produces a security code which is stored on a stored value card. Cards are supplied to the issuer in security user mode, and stored in a dispensing machine. The issuer activation key is also relayed to the dispensing machine and stored on the ASAM. Upon purchase by a customer, the issuer activation key is used within the machine by the ASAM to reproduce the security code and to activate a card. An activation control counter (ACC) is stored within the ASAM and is decremented for every attempt at activation of a card. ASAMs are maintained in the field using a dial-up connection to a central computer with a control secure application module (CSAM), or using a field secure application module (FSAM) that is created at a central location using the CSAM. Each FSAM is able to update a limited number of ASAMs. A hierarchy of keys is used by the CSAM, the FSAMs and ASAMs to ensure security.
    • 在分配点安全地启用储值卡使用卡分配机内的便携式激活安全应用模块(ASAM)激活每张卡。 每个卡都有标准用户模式和安全用户模式。 在标准用户模式下,卡被激活并准备使用。 在安全用户模式下,该卡不活动,不能用于购买。 发行人向出具存储在储值卡上的证券代码的卡供应商提供发行人激活密钥。 卡以安全用户模式提供给发行者,并存储在分发机器中。 发卡人激活密钥也被中继到分发机并存储在ASAM中。 在由客户购买时,ASAM在机器内使用发行者激活密钥来再现安全码并激活卡。 激活控制计数器(ACC)存储在ASAM中,并且在激活卡时每次尝试都减少。 使用与控制安全应用模块(CSAM)的中央计算机的拨号连接或使用使用CSAM在中央位置创建的现场安全应用模块(FSAM),在现场维护ASAM。 每个FSAM都能够更新有限数量的ASAM。 CSAM,FSAM和ASAM使用密钥层次来确保安全性。
