What are the main differences between a covert timing channel and a covert storage channel?

I am trying to find the differences between a covert timing channel and a covert storage channel in terms of detectability, performance, features, and any other advantages and disadvantages.

Is there any resource that directly compares the advantages and disadvantages of the two attacks?

How can we protect encrypted files and directories from being fingerprinted when stored on online storage services?

Assuming that online storage providers are considered untrusted, if files and directories are encrypted, how can these be protected against fingerprinting?

The files are encrypted using rclone’s implementation of Poly1305 and XSalsa20 before being backed up to the cloud provider.

According to rclone’s documentation, the available metadata is file length, file modification date and directory structure.

  • What can be identified?
  • What can be inferred?
  • What attack vectors are there against the encrypted files and directories if the online storage provider is compromised assuming the passphrase is at least 24 characters long and is a combination of alphanumeric and special characters (uppercase and lowercase) as well as salted with similar entropy?

The encrypted data is considered to be sensitive.

How can I protect those files from being fingerprinted and the contents inferred such as ownership, source and the like?

Is Bitlocker secure enough for portable storage devices?

I have recently lost a U drive, which contained some important information. Fortunately, it was protected by Bitlocker. I felt the compulse to ask exactly how secure it is. Most answers on this site related to Bitlocker seem to be about built-in storage on a computer. This answer says there was a possible cold boot hack. Is it more secure to protect a U drive with Bitlocker, since you cannot use that kind of hack on a U drive? Also, that answer is 6 years old. There must have been some new developments. With the current technology that Bitlocker uses, do I need to worry that the information on my U drive could be decrypted?

Space-efficent storage of a trie as array of integers

I’m trying to efficiently store a list of strings in an array with the following constraints:

  • All strings consist of 8-bit characters (0..255).
  • The final trie is static, i.e. once it is built, no strings have to be inserted or removed.
  • Looking up a string of length $ m$ must be done in $ O(m)$ with a constant factor as low as possible.
  • The only available memory structure to store the data is an array of integers. In particular, there are no pointers or dynamic memory allocation.
  • Once an array is allocated, it cannot be resized and its memory cannot be released anymore.
  • Memory is rare, so the final data structure should be as compact as possible and no unnecessarily long arrays should be allocated.
  • Computation time is not important for the building phase, but for memory usage the consraints above apply.

Preface

My current approach is a trie that is stored in the array with the following structure:

$ $ \fbox{$ \vphantom{^M_M} \;i_0 \;\ldots\;i_{255}\;$ }\, \fbox{$ \vphantom{^M_M} \;i^*_0 \;\ldots\;i^*_{255}\;$ }\, \fbox{$ \vphantom{^M_M} \;w\;$ }\, \fbox{$ \vphantom{^M_M} \;\mathit{last}\;$ }\, \fbox{$ \vphantom{^M_M} \;B_0\;$ }\,\fbox{$ \vphantom{^M_M} \;B_1\;$ }\,\ldots $ $

where $ i_k$ is a mapping from each unique input character $ k$ to an integer $ 1 \leq i_k(c) \leq w$ with $ i^*$ being the corresponding reverse mapping of $ i$ . Each node in the trie is stored as a block $ B$ of size $ w+1$ . The mapping $ i$ is used to reduce the size of each block, because not the whole character range has to be stored but only the number of characters actually used. This comes at the expense of having one more indirection when looking up words. (The field $ \mathit{last}$ here is used as a pointer to the field after the last block in the array, used to find the next allocation point.)

Each block looks like this:

$ $ \fbox{$ \vphantom{^M_M} \;b\;$ }\, \fbox{$ \vphantom{^M_M} \;c_1 \;\ldots\;c_w\;$ } $ $

$ b$ is either 1 if the word represented by that block is in the trie, and 0 otherwise. $ c_i$ represent all unique input characters (after the $ i$ mapping). If the value of $ c_i$ is equal to 0, there is no entry for this character. Otherwise $ c_i$ is the index into the array at which the block to the following letter starts.

To build the trie, the first step is calculate the bijection $ i$ /$ i^*$ and $ w$ . Then new blocks are added with each prefix that isn’t already present in the trie.

Problem

While this approach works so far, my main problem is memory usage. The current approach is extremly memory expensive when only few words share longer prefixes (which is usally the case). Some tests show that the typical number of non-empty fields is only about 2-3% of the whole array. Another problem is that the final number of needed array fields is only available after the trie has already been built, i.e. I have to be conservative when allocating the memory to not get out of memory while adding new blocks.

My idea now was to use a compressed trie/radix trie instead with two types of blocks: 1) the ones above that represent nodes with several children, and 2) compressed blocks (similar to C char arrays) that represent suffixes in the trie. For example, when the words apple juice and apple tree should be stored in the tree, there would be seven normal blocks for the common prefix apple and a compressed block for each juice and tree. (Perhaps that would also allow to merge common suffixes for words with different prefixes.)

The problem with this is that is may lead to gaps in the array while building the trie. Consider the situation in the above example, in which only apply juice is stored as a compressed block in the trie. Now apple tree is inserted, which would lead to a removal of the apple juice block and addition of juice and tree blocks instead, which will not fit into the left hole in general.

Under the given constraints, can anyone see an algorithm to store strings most efficiently in the array while keeping the linear lookup time?

Why does Samsung access my contacts and storage if I use their store?

If I want to access the Galaxy Store on a Samsung Galaxy phone I have to agree to a set of terms (Legal information). These terms are excerpted below:

All content made available to you by the Samsung Galaxy Store is subject to the terms and conditions set forth below…

In order to provide you with and further improve relevant services, the Samsung Galaxy Store accesses Phone, Contacts, and Storage. It also collections your device information (e.g. IMEI and model name) and service usage history…

I understand why it would collect “device information”, as any software downloaded and installed on your device would operate best if the software is tailored for a specific device/OS version etc. I assume these are the same reasons why a web page is given the operating system and browser you are using to access that page.

However can anyone give a good reason why Samsung would access my contacts? I’m not exactly comfortable with this, especially as I don’t see any reason for it for the purposes of making an ordinary app work. Also, when it says that it accesses my storage, does that mean that Samsung has access to my media stored on my phone? By that I mean documents, videos, photos etc?

Also I’m not sure if this question should be asked at another SE site maybe instead of here?

Credential Storage for Partner/Vendor Accounts

We work with many other companies to do data exchange. As an example, we might work with COMPANY A to send them sensitive data over SFTP. This would be done by them giving us an SFTP Host/Account/Password. We configure our side for the connection and have a process to push those on an interval.

My question is not about how we store that in our application, but rather, if/how those credentials should be stored in case of need for future reference. We typically put those in a password manager like KeePass, which is in our own network in the office behind locked doors on computer that require passwords, access/permissions and another password for KeePass.

Is it considered ok to store such usernames and passwords in this manner if it’s been provided by another company, but for us to connect to them? Or is there some reason we should enter the info into our app and never see it again without asking them to verify it themselves?

Storage of SSL private key in load balancer VS HSM

I have a setup whereby the SSL certificates are terminated at the load balancer (i.e. Load balancer to web server is in plaintext). In order to do the SSL termination, the private key is stored on the load balancer itself. I do have a HSM in a data center.

I was told by security guys that best practice is to store the private key in a HSM.

I have read Should SSL be terminated at a load balancer? and I understand that there is nothing wrong in terminating SSL encryption at the load balancer.

However, should the private keys be stored in the load balancer itself (from a security perspective)? Are there any technical challenges in storing the SSL private keys in a central HSM instead?
