Defence Intelligence Agency
This agency was established on 5 March, 2002 with the appointment of Lt. General Kamal Davar as the first Director General (DG). The DG reports to the Chief Of Defence Staffs (CDS). It is supposed to be the nodal agency for all defence related intelligence, thus distinguishing it from the R&AW. Much of the agency's budget and operations are classified.

DIA has control of Indian Army's prized technical intelligence assets – the Directorate of Signals Intelligence and the Defence Image Processing and Analysis Centre (DIPAC). While the Signals Directorate is responsible for acquiring and decrypting enemy communications, the DIPAC controls India's satellite-based image acquisition capabilities. The DIA also controls the Defence Information Warfare Agency (DIWA) which handles all elements of the information warfare repertoire, including psychological operations, cyber-war, electronic intercepts and the monitoring of sound waves.

Joint Cipher Bureau
The Joint Cipher Bureau works closely with the IB and R&AW. It is responsible for cryptanalysis and encryption of sensitive data. The inter-services Joint Cipher Bureau has primary responsibility for cryptology and SIGINT, providing coordination and direction to the other military service organizations with similar mission. Most current equipment providing tactical intelligence is of Russian origin, including specialized direction finding and monitoring equipment.

The Joint Cipher Bureau is also responsible for issues relating to public and private key management. Cryptographic products are export-controlled licensed items, and licenses to India are not generally available for products of key length of more than 56 bits. The domestic Indian computer industry primarily produces PCs, and PC-compatible cryptographic products have been developed and are being used commercially. More robust cryptologic systems are not commercially produced in India, and progress in this field has been slow due to the general unavailability of technology and know-how. Customised cryptographic products have been designed and produced by organizations in the defense sector are engaged in the implementation of cryptographic techniques, protocols and the products.
