zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Introduction
4. Increasing the minimum password strength with regard to the mail accounts of the users, results in a
decrease in the risk of a hacker guessing the passwords correctly. The Password Strength
Configuration interface ofWHM needs to be used for defining the minimum password strength for the
mail accounts of the users. It is recommended that the default minimum password strength be set to at
least 50.
WHM >> Home >> Security Center >> Password Strength Configuration

Configuration of the Password’s Strength
5. Enabling the service of Greylisting helps protect a server against spam or unwanted email.When this
service has been enabled, any email from a sender that is unrecognized by the server, is temporarily
rejected by the mail server. In the event that the email is legit, there are attempts to resend it by the
originating server, after a delay. Once enough time has passed, the email is accepted by the server.
In order to enable this feature, you need to navigate to the Greylisting interface of WHM and then
click Off to toggle the status of the feature.
WHM >> Home >> Email >> Greylisting

Enable Greylisting
6. Protection against brute force attacks for a server is ensured by cPHulk. Enabling cPHulk helps to
reduce the chances of brute force attack being used by a hacker for gaining access to the mail accounts
of a server.
You need to navigate to the CPHulk Brute Force Protection interface ofWHM, for enabling this
feature.Then you need to click Off in order to toggle the status of the feature.

8. Spammers cannot interact directly with the remote mail servers when SMTP Restrictions feature is
enabled. Moreover, they cannot work around the settings for mail security either.You need to navigate
to the SMTP Restrictions interface in WHM and click Enable in order to enable this feature.
WHM >> Home >> Security Center >> SMTP Restrictions
The outgoing email connection attempts to the MTA (Mail Transfer Agent), the root user and to the
mailman system user are restricted by this feature. Moreover, this feature makes sure that both scripts
and users use the sendmail binary of Exim.

10. Certain settings that are present in the Mail section of the Tweak Settings interface inWHM, aid in
preventing email abuse.These settings are mentioned in the following slides.
10
Tweak Settings
11. This setting serves the purpose of specifying the maximum number of emails which can be sent by each
domain in every hour. Its default setting is Unlimited.The following points need to be mentioned in this
context:
Email send limits are enforced by the system only on remote email deliveries.
This setting will not appear if the Exim Mail Server service in the Service Manager interface ofWHM is
disabled.WHM >> Home >> Service Configuration >> Service Manager
This setting will not function if the Eximstats driver in the Service Manager interface ofWHM is
disabled.WHM >> Home >> Service Configuration >> Service Manager
This setting doesn’t override the below-mentioned settings:
Maximum Hourly Email by Domain Relayed
Maximum percentage of failed or deferred messages a domain may send per hour
It is recommended that such a value be specified that is not Unlimited in order to prevent email abuse.
11
Max Hourly Emails Per Domain
12. If the option for Max Hourly Emails Per Domain is set to 500, then each of the hosted domains can
send 500 email messages in every hour.You can use the setting, the percentage of email messages
(above the account’s hourly maximum) to queue and retry for delivery, for specifying a soft limit.
12
Max Hourly Emails Per Domain (Continued)
13. When you want to specify values for an individual package or an individual account, you need to use
the Edit a Package interface of WHM or the Modify an Account interface ofWHM.
WHM >> Home >> Packages >> Edit a Package
Or
WHM >> Home >> Account Functions >> Modify an Account
You need to carry out the below-mentioned steps for manually editing the cpuser file, in order to
enable this setting from the command line.
Open the file, /var/cpanel/users/username from the command line. In it, the term “username”
represents the desired account username.
Add the MAX_EMAIL_PER_HOUR key in this file and specify the selected username’s value.
Run the script, /usr/local/cpanel/scripts/updateuserdomains

Account-Specific Max Hourly Emails Per
Domain Settings
14. This setting makes sure that the nobody user is denied the ability to send mail to a remote address.
The default setting is set to On. It is recommended that you select the On option to prevent email
abuse. It is the PHP and CGI scripts, which usually run as the nobody user. You need to enable the
suEXEC or mod_php modules in the Apache configuration in order to use a PHP or CGI script to
send mail.
14
Prevent “nobody” from Sending Mail
15. It is specified by this setting if the outgoing messages for later delivery should be queued, once a
domain reaches its limit with regard to outgoing messages per hour. This setting’s minimum value is
100 and its maximum value is 10,000.
The following key points need to be mentioned in this context:
This option needs to be set to 100 in order to force the failure of all outgoing messages, once the
domain reaches its limit.
This setting will not appear if the Exim Mail Server service in the Service Manager interface ofWHM is
disabled.WHM >> Home >> Service Configuration >> Service Manager
This setting will not function if the Eximstats driver in the Service Manager interface ofWHM is
disabled.WHM >> Home >> Service Configuration >> Service Manager

The Percentage of Email Messages (above the Account's Hourly
Maximum) to Queue and Retry for Delivery
16. Through this setting the maximum percentage of failed or deferred messages, which might be sent by your
domain in every hour, can be specified.The default for this setting is set to Unlimited. Outgoing mails from a
domain are temporarily blocked by your server, when both of the below-mentioned conditions are true.
The number of failed or deferred messages sent by the domain equals that specified in the setting,
Number of failed or deferred messages a domain may send before protections can be triggered.
In the total number of sent messages, the percentage of failed or deferred messages is equal to or
greater than the percentage that has been specified.
All outgoing and local mail, for the previous hour, are examined by the system for determining if these
conditions are met.When only one of the above-mentioned conditions is true, outgoing mail isn’t blocked
by the system.
