The CRSI has been founded for:
- Supporting and promoting research activities in cryptology and data security in India.
- To arrange lectures, discussions, workshops, seminars conferences etc. for motivating and guiding the young Indian researchers in the field of cryptology and data security.
- Organizing the annual events INDOCRYPT- the International Conference on Cryptology and security, the National Workshop on Cryptology and National Level Instructional Workshop on Cryptology
Institute of Mathematical Sciences, Chennai
Founded by Alladi Ramakrishnan in 1962, the IMSc, Chennai is a national Institute for fundamental research in frontier disciplines of the mathematical and physical sciences, theoretical computer science, mathematics and theoretical physics. Research at IMSc is supported by the Department of Atomic Energy, Government of India and the Government of Tamil Nadu. Located in south Chennai in the Adyar- Taramani area, the institute is based in the verdant surroundings of the Central Institutes of Technology (CIT) campus.
About Amrita Vishwa Vidyapeetham
With headquarters at Coimbatore and campuses at Amritapuri, Kochi, Bangalore and Mysore, Amrita Vishwa Vidyapeetham is emerging as one of the fastest growing institutions of higher learning in India. The institution is managed by the Mata Amritanandamayi Math. Satguru Sri Mata Amritanandamayi Devi, Amma, one of the foremost humanitarian leaders in the world today, is the Chancellor of Amrita Vishwa Vidyapeetham.
Amrita started in 1994 as a School of Engineering in an obscure village named Ettimadai, at the foothills of Bouluvanpatty ranges of the Western Ghats in Coimbatore District of Tamil Nadu. Today, Amrita has a student population of over 14,000 and faculty strength of 1500. There are over 220 faculty members with a Ph.D qualification. Research is a very significant activity in the institution.
