Export Grade Cryptography

What is export grade cryptography ?



Since World War II, many countries including the U.S., U.K. and others, have regulated the export of cryptography in the interest of national security till 1992.

Those countries used to believe that they had developed more advanced cryptographic solution than others and they wished to monitor the communication of other countries and hence restricted the advanced cryptographic solution to other nations, by their companies.
Restriction had been eased down in 1992 and in 2000 but some are still there.


Only those cryptography solutions which can be breaked by security agencies, were allowed to export and were known as Export Grade Cryptography. Ciphers itself are not of Export Grade as they properly follows algorithms. It is the use of cryptographic keys that are deliberately weekend so that security agencies can crack them as and when needed.

The export-grade encryption had 512 bits, the maximum allowed under U.S. restrictions designed to limit trade in military technologies in the 1990s.

Availability of 5 GHz WLAN Channels in India under unlicensed band

Availability of 5 GHz WLAN Channels in India under unlicensed band  In India, Wireless Planning and Coordination Wing of Department of Telecom, under Ministry of Communication takes care of licensing of radio frequencies.  In the latest National Frequency allocation plan 2018 (https://dot.gov.in/sites/default/files/NFAP%202018.pdf), Government of India (GoI), exempted the licensing requirements of the following radio frequency ranges for wireless usage and a gazette notification has also published for this (https://dot.gov.in/sites/default/files/License%20Exemption%20in%205%20GHz%20G_S_R_1048%28E%29%20dated%2022nd%20October%2C%202018_0.pdf)  -- 1.  5150-5250 2. 5250-5350 3. 5470-5725 4. 5725-5875 References

Identity PSK ( iPSK)

With the evolution of IoT (Internet of Things), devices that connect wirelessly have increased many folds. From webcams, Smartwatches, fitness bands, firestick, Alexa, Google Home, and many more.., everything is going wireless for connectivity and so does the security threat. The main concern with IoT devices is the unavailability of the full wireless protocol stack (and in the majority of devices, support of 802.1x is not available). So, previously we only have the WPA-PSK option for connecting the IoT devices.  In WPA*-PSK (WPA or WPA2) WLAN, a Pre-Shared Key (PSK) is configured and distributed to all the clients that connect to the WLAN. This leads to PSK leakage, and it can be accessible to unauthorized users (due to the nature of common PSK across all the devices).  Therefore, there was a need to provision unique PSK or Multiple PSK per SSID. Identity-PSKs are unique pre-shared keys created for clients/groups on the same WLAN. Features of iPSK:-   1.Unique PSK for individual Cli

Summary report of APNIC 55 (APRICOT 2023) Meeting held in Manila, Philippines

APNIC Logo The APNIC 55 meeting was held in Manila, Philippines from 20th Feb to 02nd March 2023. The meeting was hosted by PhNOG, The Philippine Network Operators Group (PhNOG) and supported by DOST- Advanced Science and Technology Institute. Every year, APNIC conferences are held twice, the first of each year is held in conjunction with APRICOT and the second one is a standalone conference. The last such meeting held in India was in 2012, APNIC 33 (which was in conjunction with APRICOT 2012).  APNIC 55 meeting was unique in multiple senses –  i. Firstly, because of the possibility of potential hijack [1] [2][3] of the APNIC Executive Council by Cloud Innovation Ltd. / Larus foundation / NRS, the same organizations which have dragged AFRINIC (RIR for African Continent) into the Mauritius supreme court and at one point nearly halted the AFRINIC operations by getting its bank accounts frozen (over 25 lawsuits have been filed against AFRINIC by Cloud Innovation Ltd.).
