The intent of this document is to outline issues relating to the utilization of digital signatures on engineering related documents with the Oregon Department of Transportation. For the purpose of this document, the term engineering will include all branches of engineering performed within the agency, including surveying, geology, and any other branch that requires the placement of a seal and signature on a final product.
When I first mentioned to a colleague of mine that I was writing a book on JavaTM security, he immediately
starting asking me questions about firewalls and Internet DMZs. Another colleague overheard us and started
asking about electronic commerce, which piqued the interest of a third colleague who wanted to hear all about
virtual private networks. All this was interesting, but what I really wanted to talk about was how a Java applet
could be allowed to read a file.
Chữ ký điện tử ( electronic signature) là thông tin đi kèm theo dữ liệu nhằm mục đích xác định người chủ sở hữu của dữ liệu đó. Tính chất chức năng:
Chứng minh được tính tin cậy của thông tin.
Có khả năng kiểm tra được người ký và thời gian ký.
Có khả năng xác thực các nội dung tại thời điểm ký, nghĩa là có thể cho phép kiểm định được thông tin đúng là do một người gửi chứ không phải là người thứ 3 mạo danh và thông tin không bị sửa đổi.
All organizations, whether for profit, not for profit, or government, face issues of information technology management. While the concerns involved may differ from organization to organization, the principles of good information technology management remain the same.
Using a compilation of articles on various topics relating to technology management, Handbook of Technology Management in Public Administration addresses the management, implementation, and integration of technology across a wide variety of disciplines.
A common approach to estimating node positions is direct mea-
surement or triangulation against landmarks in the immediate one-
hop vicinity. Active Badge  relies on the closest infrared re-
ceiver to locate specialized beacons carried by tracked assets. RADAR 
relies on a centralized database of signal ﬁngerprints from land-
marks obtained at all locations and orientations to localize a node.
Lorincz andWelsh  propose a similar RF ﬁngerprint-based node
localization technique that relies on strength signatures and a dis-

(BQ) In this age of universal electronic connectivity, viruses and hackers, electronic eavesdropping, and electronic fraud, security is paramount. This text provides a practical survey of both the principles and practice of cryptography and network security. The book is divided into 2 parts, part 2 from chapter 16 to chapter 23.
The retail trade has developed a system (without consulting the banking sector) which makes
payments by bank card possible without any authorisation. This system is known as the electronic
direct debit system (ELV). The customer’s signature on the receipt or an additional document
authorises the dealer to collect the cost of the purchase by direct debit. However, the risks of a direct
debit being returned on account of an objection or lack of cover, or possibly because the card has
been blocked, are borne solely by the retail outlet.
