GPG novice here so please bear with me.
From what I understand, when you generate a keypair with GPG it will automatically create a subkey pair (sub, ssb).
If I wanted to give these to another party where they could encrypt messages with t… Continue reading GPG Questions About Exporting Subkeys to File
Is there a standard format for storing/exchanging encrypted data along with the key needed to decrypt it (data is encrypted with a single use symmetric key and the symmetric key itself is encrypted with asymmetric key for the receiver)?
We… Continue reading Format for data & symmetric key exchange/storage
Say there is a secret encryption key that a third party has to handle. The third party is supposed to destroy the secret key when they are done, and tell everyone else it was destroyed and therefore safe to use. However, if the third party… Continue reading Can a large corporation make a believable promise
I have two servers with a pair of RSA public and private keys.
We do not use a CA for the internal communication yet and therefore we need to exchange keys without CA.
I need to establish a trust between two servers: I need to copy a pub… Continue reading How can we exchange public keys between two servers in a secure way?
I have been reading into PAKE protocols, specifically starting with SRP RFC2945
The gist of the requirement on the server is that the server saves triplet (username, verifier (v), salt (s)) in the credentials table.
Where verifier v = g^… Continue reading How do SRP (and PAKE generally) protect against verifier leak
The company runs a chat room service, where users can securely send messages to one another. All users are authenticated by the service in advance, and will install software from the service onto their computer. However, none of them want … Continue reading how can the company facilitate secure chats between users without going through the trouble of private/public key pairs?
I have the following problem:
I have two platforms, one of them has a TPM. I need to transfer data between these two platforms, so I first determine an attestation, in order to confirm that the destiny platform is the original and not a c… Continue reading TPM Attestation and key exchange
I need to build a project for uni where I need to transfer data securely from a client to a server. I can’t use PKI structures and can’t save pre-shared secrets (Imagine travelling to china and some bad guys check your pc). The only secret… Continue reading How to securely exchange a symmetric key over a unsecure netwrok
In sensor nodes, there arises a need to store the master secret key safely. Which is the most perfect location to store the key when the sensor nodes (such as implanted body sensor node) are highly resource-constrained ones?
Continue reading Storage of secret key in resource-constrained sensor nodes
In Trivium cipher, 80-bit key and 80-bit IV (initialization vector) are used initially to set up the initial state. I would like to know, (i) role of IV in stream cipher? (ii) can we make IV a secret parameter? and (iii) how IV values are … Continue reading What is the significance of IV in stream ciphers like Trivium? [migrated]
