Abstract
Provided are a security apparatus and an operation method thereof. The security apparatus comprises a core circuit which performs a security function by using an authentication key such as a secret key provided by a physically unclonable function (PUF). The security apparatus may receive event information indicating that the security apparatus is in a security-vulnerable state such as a case where the security apparatus is stolen or lost. In such case, a power management circuit can apply at least one electrical shock of overvoltage and overcurrent to the security apparatus to cause physical damage to the security apparatus, so that the core circuit does not perform the security function normally.
