M.Tech.(CrS)

1. About the ISI M.Tech. (CrS) Program

The M.Tech. in Cryptology and Security (CrS) at the Indian Statistical Institute (ISI) is a prestigious two-year postgraduate program designed to build expertise in theoretical and applied cryptography, cybersecurity, coding theory, and information security.Applicants typically:

• Hold a Bachelor’s/Master’s degree in Mathematics, Statistics, Computer Science, or Engineering.

• Must qualify through ISI’s highly competitive entrance examination followed by an interview.

• Aim for careers in cybersecurity research, cryptography labs, data security for corporates, and PhD programs in top institutes worldwide.

2. What Our Coaching Program Offers

Interactive Live Classes

• Conducted in online (Zoom/Skype) and offline (Kolkata & New Delhi centres) formats.

• Comprehensive coverage of:

  • Abstract Algebra & Number Theory (Groups, Rings, Fields, Modular Arithmetic)

  • Linear Algebra & Probability (for cryptographic modeling)

  • Coding Theory (Error detection, Error correction, Linear codes)

  • Classical & Modern Cryptography (RSA, AES, Elliptic Curve, Public-Key Systems)

  • Network Security & Secure Communication Protocols

  • Algorithm Design, Complexity, and Basic Programming (C/Python) for cryptography

  • Interview preparation and research proposal guidance for ISI’s final round

• Every session is recorded, so students can revisit lectures anytime.

Exam-Focused & Application-Oriented Training
