摘要： Embodiments describe a system and/or method for multiple party digital signatures. According to a first aspect a method comprises establishing a first validity range for a first key, establishing a first validity range for at least a second key, and determining if the validity range of the first key overlaps the first validity range of the at least a second key. A certificate is signed with the first validity range of the first key and the first validity range of the at least a second key if the validity ranges overlap. According to another embodiment, signage of the certificate is refused if the first validity range of the first key does not overlap with the first validity range of the at least a second key.

摘要： Methods and systems enable receiving on mobile devices credits, tokens or coupons from mobile TV broadcast service providers. Credits may be delivered via direct unicast messages such as SMS or e-mail, or via broadcast provisioning messages. Subscription response messages may be used to deliver credits to mobile devises which transmit a request for service. Broadcast service providers may push credits to mobile devices by transmitting a solicited pull message or a credit grant push message. Credits may be sent to mobile devices within a credit response message or a long term decryption key message. Credits may be used a purchase transaction, with the broadcast service provider controlling redemption of credits by sending an a long term decryption key message via a unicast network or a short term decryption key message via the broadcast network to cause mobile devices to decrement their stored credits.

摘要： Disclosed is a method for mutual authentication between a station, having a digital rights agent, and a secure removable media device. The digital rights agent initiates mutual authentication by sending a message to the secure removable media device. The secure removable media device encrypts a first random number using a public key associated with the digital rights agent. The digital rights agent decrypts the encrypted first random number, and encrypts a second random number and a first hash based on at least the first random number. The secure removable media device decrypts the encrypted second random number and the first hash, verifies the first hash to authenticate the digital rights agent, and generates a second hash based on at least the second random number. The digital rights agent verifies the second hash to authenticate the secure removable media device.
