Given Seed, keyfragment and cipher text, how to get actual text using LFSR? [duplicate]

$$\text{seed = 1100010001101001}$$

$$\text{key fragment = 110001010000101011001011111101100}$$

$$\text{cipher text = 0xa50b839547f7fe7cf882}$$

What is the actual text and how to evaluate it? I would like to know the exact procedure to do it.

• I went through that duplicate but I want more detailed explanation. Detailed explanation in the sense, workout that example and upload a pic or something...I got the polynomial to be x^16+ x^12+x^3+x+1. But i dont know what to do next – Hari Hara Kumar Rajanala Jan 24 '19 at 19:36
• What kind of detailed explanation do you need? This is exactly the same question. The Berlekamp-Massey result is same. Only the seed and key fragment are different. – kelalaka Jan 24 '19 at 22:12
• I've closed this, please indicate what you are missing in the answer given for the other question (besides the values being different) or ask a new / different question. – Maarten Bodewes Jan 25 '19 at 7:03
