Security of APL applications packages

Content Provider ACM Digital Library
Author Penfield, Paul
Abstract By the term “applications package” is meant a set of interacting APL functions and variables that a user calls, along with certain “background” functions and data that are only called indirectly. If there is a proprietary interest in the package, then it is necessary to devise techniques to assure the security of the package. An interpreted language like APL might be thought to pose severe security problems, since (unlike a compiled language such as FORTRAN) the source code is always somewhere nearby. However, with proper design, reasonable security (consistent with the value of the goods protected) can be achieved. This paper deals with security for packages installed both on private computers, and on commercial time-sharing systems, with the emphasis on the latter.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
