I am learning about stream ciphers, which apparently are unpopular. I just want to have a better idea of some basic algorithms that are in use or were in use till recently.
I checked:
the OTP: Apparently great but unpractical
Linear Congr… Continue reading Common applications and simple implementations of stream ciphers [migrated]
I have done some search here but I can’t understand how phones and antennas share the keys used for encryption and decryption.
As far as I understand, mobile phones today use LTE i.e 4G (sometimes they downgrade 3G, 2G etc because of cover… Continue reading Cell tower to cell phone encrypted communication
I am writing a small app.
It creates a session once the user authenticates. I am aware of this definition of fixation attack from owasp.
Attacker uses the app
In this App, once they log out the sessionID is destroyed. If they are still log… Continue reading A few questions about fixation attack
I am creating a small login system. It looks like the standard username/pwd and user can either log or register.
If they pass (authenticate), I create a session cookie that will be sent with the header every time, so that the user is not l… Continue reading Session cookie security
I read that phones encrypt communication (GSM as implemented in 2G,3G..) – particularly voice as SMS are unencrypted – using a stream cipher.
Symmetric Stream ciphers use the flip-flop machinery to start (a true random generator imho), and… Continue reading How is the stream cipher key shared on GSM?
As you will know most search engines pass the search information url-encoded, i.e a get request with the parameters on it.
But given all the fuzz about security and surveillance, why aren’t SEs encrypting the data just by sending it in a P… Continue reading Why aren’t search engines encrypting search queries? [duplicate]
