, tạo điều kiện giao multicast IP và truyền hình độ nét cao (HDTV) lập trình và cho phép videostreaming, thành lập lưu trữ video. CAVNER tính năng một cấu trúc mở để hỗ trợ các hoạt động mạng lưới multivendor. CAVNER cũng tạo điều kiện truyền tải video không nén dữ liệu thông qua mạng DWDM (bước sóng dày đặc-Division Multiplexing). | National Center for Supercomputing Agency NCSA The National Center for Supercomputing Agency NCSA employs a combination of solutions including digital certificates and public key private key and personal pass phrases for safeguarding NCSA computing resources. NCSA participants are also required to access a CA Certificate Authority and obtain a certificate of authentication prior to connecting to secure NCSA networks. In addition NCSA employs Secure Shell SSH authentication at major network sites. Endorsed by the IETF Secure Shell Working Group SSH v2 Secure Shell Version 2 allows the creation of RSA asymmetric key pairs for enabling strong encryption. Typically SSH supports remote log-ons and encrypted Web sessions. Digital Signature Marketplace Communication Intelligence Corporation CIC The Communication Intelligence Corporation CIC develops secure electronic signature solutions for E-commerce transactions. These solutions employ biometric measurements based on timing speed and style that characterize an individual signature. Moreover the CIC supplies software technologies for enabling dynamic signature verification multilingual handwriting recognition systems and natural messaging solutions. The CIC also supports sign-on products for Pocket PCs to authenticate user identification prior to enabling access to the system. PUBLIC KEY INFRASTRUCTURE PKI PKI Features and Functions A de facto standard for implementing a secured infrastructure a Public Key Infrastructure PKI implementation enables public and private entities to conduct E-commerce and E-business transactions via the Web in an environment of total trust. A PKI solution supports the utilization of a pair of public and private keys a corresponding digital certificate and authentication services. PKI deployments also enable key distribution generation and recovery operations and ensure nonrepudiation of agreements and data confidentiality. Moreover PKI installations .
