摘要： The aim of the present invention consists of reducing the switching time from one reception channel to another. In fact, this reduction will be particularly discernable since the number of different rights stored in a security module of a multimedia unit or decoder is high. When a user selects a service among those proposed by an electronic programs guide, an access control module explores a stored service information table in order to extract an access condition associated to the service. This access condition allows determining an index in a rights table stored in the access control module of a right that fulfills the access condition. The access control module transmits to the security module the index thus determined alone or accompanied by a control message. This index allows the security module to find quickly the right that it compares afterwards with the access condition included in the control message after decryption of the latter.

摘要： The objective of the present invention is to propose an accounting method of the consumption of transmitted services per time unit to a decoder in a system implementing a content encrypted by control words, the latter being modified according to a period named crypto-period.This method consists in verifying if the time-current (TC) is comprised in a time variable (Rdate) representative of the authorisation time of use of the service and, if this is the case, decrypting and returning the control words to the decoder, and if it is not the case, debiting an amount (CT) corresponding to a time of use (AT) and recharging the time variable (Rdate) with a corresponding time.
摘要翻译：本发明的目的是提出一种在实施由控制字加密的内容的系统中，解码器将每个时间单位的发送服务的消费计费方法，后者根据称为密码周期的周期进行修改。该方法包括验证时间电流（TC）是否包含在表示服务使用授权时间的时间变量（Rdate）中，如果是这种情况，则将控制字解密并返回到解码器，如果不是这种情况，则对应于使用时间（AT）的金额（CT）和相应时间的时间变量（Rdate）充值。

摘要： The aim of this invention is to assure the portability of an electronic certificate and the security of the private key which are part of the certificate X509. In fact, it is important that this certificate is not used for purposes uncontrolled by the holder, such as identity usurpation, the authorization of non-desired transactions or the reproduction of transactions (replay). This aim is reached by a storage and transporting method for an electronic certificate, said certificate having an authority section for the issuing authority, a holder section for the holder of the certificate and a signature section determined by the issuing authority, characterized in that all or part of the holder section is contained in a removable security module and that at least the authority section is contained in a host computer.
摘要翻译：本发明的目的是确保作为证书X509的一部分的电子证书的可移植性和私钥的安全性。事实上，重要的是，该证书不被用于持有人不受控制的目的，例如身份篡夺，不需要的交易的授权或交易的再现（重播）。该目的通过电子证书的存储和运输方法达成，所述证书具有发证机关的授权部分，持证人持有人的证书持有人部分和由发行机构确定的签名部分，其特征在于，全部或持有者部分的一部分包含在可拆卸安全模块中，并且至少该授权部分包含在主机中。

摘要： A method is disclosed for access control to conditional access data in a multimedia unit comprising at least one security module. This process includes:reception by the multimedia unit of a control message ECM containing at least one control word cw; transmission of this message ECM to said security module, this control message being associated to a message decryption right; determination of a validity date of the ECM control message decryption rights associated to said security module; determination of the present date; comparison of the present date with the expiration date of the decryption rights and determination of whether the present date is prior to the expiration date. In the affirmative case, decryption of the control message ECM and sending of the control word cw to the multimedia unit occurs In the negative case, reading of a value contained in a counter of the security module and comparison of this value occurs, to determine whether this value is comprised within a range authorizing decryption. Further, in the affirmative case, modification of the value of the counter according to a pre-established rule, and decryption of the control message ECM and sending of the control word cw to the multimedia unit also occurs. Finally, in the negative case, access to the conditional access data is blocked.

摘要： The invention concerns a method for controlling access to encrypted data by control words (CW), said control words being received by a security module in control messages (ECM) and returned to a unit operating on (STB) the encrypted data. The method includes the following steps: receiving a first control message (ECM) comprising at least one control word (CW) and a time stamp (TS), receiving a second control message (ECM2) consecutive to the first control message (ECM1), said second message comprising at least one control word (CW) and a time stamp (TS), determining a duration corresponding to the difference between the time stamps (TS) of the two consecutive control messages (ECM1, ECM2), if said duration is less than a predefined duration (CP), incrementing an error counter (CE), and if said duration is not less than said predefined duration, decrementing said error counter (CE), returning the control word (CW) to the operating unit (STB) after a waiting time depending on the value of the error counter (CE).

Each unit has a security module (SC) comprising at least one global encryption key used in relation with an encryption module. This method is characterized in that it consists of dividing the totality of the security modules allowing access to encrypted data originating from a determined provider into at least two groups (GR1, GR2), a first group of security modules having a first configuration of the security elements and a second group of security modules having a second configuration of the security elements, the first configuration being different from the second configuration.

摘要： Example embodiments are directed to a duration computing method in a security module inserted into an apparatus including an internal clock. The apparatus may receive a digital data stream encrypted via control words contained in a control message ECM. The method may include receiving data coming from the internal clock of the apparatus including a current temporal information, storing the data representing the current temporal information in the security module, receiving the control message ECM to decrypt at least one control word, reading previous data representing a previous temporal information at a moment of processing the previous control message ECM, and processing the control message ECM when the current temporal information is temporally ahead of the previous temporal information.
