    • Methods, apparati, and computer-readable media for securely loading a software module over a communications network from a software provider (SP) (101) onto a tamper resistant module (TRM) (103). A method embodiment of the present invention comprises: the SP (101) encrypting, using at least one transport key, at least one portion of the software module, each portion having an indication of location of the portion; the SP (101) encrypting each transport key and each indication using an asymmetric TRM public key, thereby forming a key transformation unit (KTU) (207), the TRM public key (150) having a corresponding TRM private key (190), the TRM public key (150) and corresponding TRM private key (190) being certified by a first certification authority (CA-1) (109); the SP (101) digitally signing the encrypted portion(s) with at least one asymmetric SP private key, each said SP private key having a corresponding SP public key, to produce a signed software module, each SP public key being certified by a second certification authority (CA-2) (119), CA2 (119) being different than CA-1 (109); and the SP (101) transmitting the portion(s), the KTU (207), and the signed software module to the TRM (103) over the communications network; and the TRM (103) recovering the transport key(s) and the indication(s) by decrypting the KTU (207) using the TRM private key (190); the TRM identifying the portion(s) using the recovered indication(s), verifying the certified SP public key using the public key of CA-2, authenticating the portion(s) using the certified SP public key; and decrypting the portion(s) using the recovered transport key(s).
    • 用于通过通信网络将软件模块从软件提供商(SP)(101)安全地加载到防篡改模块(TRM)(103)上的方法,装置和计算机可读介质。 本发明的方法实施例包括:SP(101)使用至少一个传输密钥加密软件模块的至少一部分,每个部分具有该部分的位置的指示; SP(101)使用非对称TRM公开密钥加密每个传输密钥和每个指示,由此形成密钥变换单元(KTU)(207),具有对应的TRM私钥(190)的TRM公钥(150), TRM公钥(150)和由第一认证机构(CA-1)(109)认证的相应TRM私钥(190); 所述SP(101)用至少一个非对称SP专用密钥对所述加密部分进行数字签名,每个所述SP专用密钥具有对应的SP公开密钥,以产生签名的软件模块,每个SP公钥由第二 认证机构(CA-2)(119),CA 2(119)不同于CA-1(109); 和通过通信网络向TRM(103)发送所述部分的SP(101),所述KTU(207)和所述签名的软件模块; 和TRM(103)通过使用TRM私钥(190)解密KTU(207)来恢复传输密钥和指示; 使用恢复的指示识别部分的TRM,使用CA-2的公钥验证经认证的SP公开密钥,使用认证的SP公钥对部分进行认证; 以及使用恢复的传输密钥来解密所述部分。

    • A realtime electronic communications system utilizes an instant-messaging server. A first computer includes a first instant-messaging client. The first client is adapted for logging the first computer in to the server, and communicating to the server connecting information of the first computer. A second computer includes a second instant-messaging client. The second client is adapted for logging the second computer in to the server, and communicating to the server connecting information of the second computer. An external device is operatively connected to the second computer. Respective connecting information of the first and second computers is utilized for effecting realtime peer-to-peer communication between the first and second computers, whereby the first computer interfaces with the external device in realtime.
    • 实时电子通信系统利用即时通讯服务器。 第一台计算机包括第一个即时通讯客户端。 第一客户机适于将第一计算机记录到服务器中,并且与连接第一计算机的信息的服务器进行通信。 第二台计算机包括第二个即时通讯客户端。 第二客户机适于将第二计算机记录到服务器中,并且与服务器通信连接第二计算机的信息。 外部设备可操作地连接到第二计算机。 利用第一和第二计算机的相关连接信息来实现第一和第二计算机之间的实时对等通信,由此第一计算机实时地与外部设备进行接口。
