Hi everyone, I am Arpit Gupta, an Electronics and Communication undergraduate at the Indian Institute of Technology, Roorkee. I have been in touch with GNU Radio for about a year now. I successfully participated in *GSoC'19* with *GNU Radio*, building a *Block Header Parsing Tool*. More details regarding my project can be found here <https://headerparser.wordpress.com/>. The *complete code* can be found here <https://github.com/gnuradio/gnuradio/pull/2750>. I'm very interested to contribute again in GNU Radio this year. I have gone through the GSoC ideas list and the project I'm interested in working on the most is *GRC: View Only Mode (Secure).* The project has a very strong security implication on the GRC (GNU Radio Companion) as it would stop or ask for user permission before executing arbitrary python code. For example, *Python Module Block* allows you to run arbitrary python code*. *The idea here is to add *persistent cache* to the *eval* operations that would enable users to *view a flowgraph* without being executed. Persistent cache means information is stored in "permanent" memory, so data is not lost after a system restart or system crash as it would be if it is stored in cache memory. I would definitely like to work a lot more on this project, so it will be very helpful if I can get further guidance. I will be highly obliged.
Thanks. Regards, Arpit Gupta Indian Institute of Technology, Roorkee
